Introduction
45 CFR
303.8(b) states:
“(1) The State must
have procedures under which, within 36 months after establishment of
the order or the most recent review of the order (or such shorter cycle as
the State may determine), if there is an assignment under part
A, or upon the request of either parent, the State shall, with
respect to a support order being enforced under title IV-D of the Act,
taking into account the best interests of the child involved:
(i) Review
and, if appropriate, adjust the order in accordance with the State's
guidelines established pursuant to section 467(a) of the Act if the
amount of the child support award under the order differs from the amount that
would be awarded in accordance with the guidelines;
(ii) Apply a cost-of-living adjustment to the
order in accordance with a formula developed by the State; or
(iii) Use automated methods (including automated
comparisons with wage or State income tax data) to identify orders
eligible for review, conduct the review, identify orders eligible for
adjustment, and apply the appropriate adjustment to the orders eligible for
adjustment under any threshold that may be established by the State.
(2) The State may elect in
its State plan to initiate review of an order, after learning that a
noncustodial parent will be incarcerated for more than 180 calendar days,
without the need for a specific request and, upon notice to both parents,
review and, if appropriate, adjust the order, in accordance with paragraph
(b)(1)(i) of this section.”
Federal
regulations require the Office of Recovery Services/Child Support Services
(ORS/CSS) to review a support award that meets certain criteria for potential
adjustment. Reviews of child support orders fall into one of three categories.
·
3 year review, mandatory review if child(ren) are receiving IV-A cash
assistance: If it has been 3 years or more since the order was issued or
modified, the order amount for the payor
only needs to change by 10% to qualify for a potential modification. Cases that
qualify for the mandatory review will be identified by the 3 Yr Review Query
Management Facility (QMF) report.
NOTE:
ORS/CSS is only required to conduct the 3 year
mandatory review for cases that are receiving IV-A cash assistance in Utah. It
is the responsibility of the intergovernmental state to request a review if the
child(ren) are receiving financial assistance in their state.
·
3 year review, substantial change in circumstances not required: If it has been
3 years or more since the order was issued or modified on a Non-IV-A
case, the order amount for the payor
only needs to change 10% to qualify for a potential modification.
·
Less than 3 year review, substantial change in circumstances
required: If
it has been less than 3 years since the order was issued or modified, then the
requesting party must prove that there has been a substantial change in
circumstances in order to modify the order. In
addition, the order amount for the payor
must change by 15% in order to qualify for a potential
modification.
NOTE:
Generally, the payor in the above instances is the noncustodial parent (NCP). For
specified relative cases, the payor may be either or both parent(s).
Continuing,
Exclusive Jurisdiction to Modify
Prior to
conducting a review and adjustment, determine the controlling order (DCO), if
the case has multiple orders. As part of the DCO process, determine if Utah has
jurisdiction to modify the order in accordance with Utah Code 81-8-202 which
states:
“Personal
jurisdiction acquired by a tribunal of this state in a proceeding under this
chapter or other law of this state relating to a support order continues as
long as a tribunal of this state has continuing, exclusive jurisdiction to
modify the tribunal’s order or continuing jurisdiction to enforce the
tribunal’s order as described in Sections 81-8-205, 81-8-206, and 81-8-211.”
Utah Code
81-8-206 states:
“(1) A tribunal of this state that has issued a child support
order consistent with the law of this state may serve as an initiating tribunal
to request a tribunal of another state to enforce:
(a) the order if the order is the controlling order and has not
been modified by a tribunal of another state that assumed jurisdiction in
accordance with the Uniform Interstate Family Support Act; or
(b) a money judgment for arrears of support and interest on the
order accrued before a determination that an order of a tribunal or another
state is the controlling order.
(2) A tribunal of this state having continuing jurisdiction over a
support order may act as a responding tribunal to enforce the order.”
Utah Code 81-8-211 states:
“(1) A tribunal of this state issuing a spousal support
order consistent with the law of this state has continuing, exclusive
jurisdiction to modify the spousal support order throughout the existence of
the support obligation.
(2) A tribunal of this state may not modify a spousal support
order issued by a tribunal of another state or foreign country having
continuing, exclusive jurisdiction over that order under the law of that state
or foreign country.
(3) A tribunal of this state that has continuing, exclusive
jurisdiction over a spousal support order may serve as:
(a) an initiating tribunal to request a tribunal of another state
to enforce the spousal support order issued in this state; or
(b) a responding tribunal to enforce or modify the tribunal’s own
spousal support order.”
If Utah does
not have jurisdiction to modify the order, determine if the state issuing the
order has continuing, exclusive jurisdiction (CEJ) in accordance with Utah Code
81-8-205 which states:
“(1) A tribunal of this
state that has issued a child support order consistent with the law of this
state has and shall exercise continuing, exclusive jurisdiction to modify its
child support order if the order is the controlling order. . . .”
A state that
issues the controlling order has CEJ to modify the order as
long as the state is the residence of the NCP, the CP, or the child for
whose benefit the order was issued. Utah Code 81-8-205(1) further clarifies
that the parties’ residence must be considered at the time the modification is
requested when determining CEJ, as follows:
“(a) at the time of the
filing of a request for modification, this state is the residence of the
obligor, the individual obligee, or the child for whose benefit the support
order is issued. . . .”
If the state
no longer has CEJ, Utah Code 81-8-205 authorizes a tribunal to modify a
controlling order, even if the state is no longer the residence of the parties,
if the parties consent in a record or in open court
that the state may continue to exercise jurisdiction to modify the order:
“(2) A tribunal of this state that has issued a child support
order consistent with the law of this state may not exercise continuing,
exclusive jurisdiction to modify the order if:
(a) all of the parties who are
individuals file consent in a record with the tribunal of this state that a
tribunal of another state that has jurisdiction over at least one of the
parties who is an individual or that is located in the
state of residence of the child may modify the order and assume continuing,
exclusive jurisdiction. . . .”
Some common
examples of when this may occur are:
1.
The parties want the same state to have jurisdiction over both
spousal and child support; or,
2.
The parties have moved just across the state line and continue to
have a strong affiliation with the issuing state; e.g., the parties are still
employed in the issuing state.
If the
parties fail to consent in a record or open court that the state may continue
to exercise jurisdiction to modify the order, the order must then be registered
in the state having jurisdiction over the parties prior to modification of the
order in accordance with Utah Code 81-8-609, which states:
“(1) A party or
child support services agency seeking to modify, or to modify and enforce, a
child support order issued in another state shall register that order in this
state in the same manner provided in Sections 81-8-601 through 81-8-608 if the
order has not been registered.
(2) A petition for modification may be filed at the same time
as a request for registration, or later.
(3) The pleading shall specify the grounds for modification.”
Refer to
subsection Procedures – Who Conducts the Review below.
Written
Consent to Transfer CEJ
A state
without CEJ may still review an order and, if appropriate, modify the order in
accordance with Utah Code 81-8-205(1), which states:
“(b) even if this
state is not the residence of the obligor, the individual obligee,
or the child for whose benefit the support order is issued, the parties consent in a record or in open court that the
tribunal of this state may continue to exercise jurisdiction to modify the
tribunal’s order.”
If all of the parties have left the state that issued the
controlling order, the individual parties (CP and NCP) may file a notarized
written consent form with the state/tribunal that issued the order, as long as the new tribunal has personal jurisdiction over
at least one of the parties. The notarized written consent form must:
1.
State that the parties want another state/tribunal (must identify
the state/tribunal) to modify the child support order and assume CEJ;
2.
Be signed by both parties; and,
3.
A copy must be sent to the new state/tribunal.
EXAMPLE:
Facts:
a.
Child support order issued by California, Los Angeles County.
b.
CP resides in Utah and:
i.
Applies for IV-D services with ORS/CSS;
ii.
Requests a modification; and,
iii.
Wants Utah to conduct a modification review.
c.
NCP resides in Colorado and:
i.
Has work connections in Utah;
ii.
Past experiences with ORS/CSS; and,
iii.
Wants Utah to conduct a modification review.
Because Utah does not have CEJ, the order cannot be registered for
modification without a written consent form from the parties.
The CP and NCP sign and file a written consent form requesting
that the state of Utah, ORS/CSS review the child support order and modify, if
appropriate. The form is filed with the state of California,
Los Angeles County and a copy is given to the state of Utah.
Because the NCP consents to the jurisdiction of the state of Utah
and Utah already has personal jurisdiction over the CP, the order may now be
registered for purposes of modification. If the order is modified, Utah then
assumes CEJ of the order.
Procedures –
Who Conducts the Review
When you
receive a request for a review and adjustment or are conducting a 3-year
mandatory review, you must take the steps listed below.
1.
Make sure the order to be modified is the controlling order.
2.
Determine if the controlling order state still has CEJ.
a.
CEJ – If the
controlling order state has CEJ, the review must be sought in that state. If the controlling order is not a
Utah order, refer the case to the appropriate tribunal for a modification
review. Refer to CS 222 Intergovernmental Referral Methods for additional
information.
b.
No CEJ – If the controlling order state does
not have CEJ because the parties have left the state, then no state has CEJ.
i.
If the parties all reside in Utah, refer to subsection
Modification of an Out-of-State Order When all Parties Reside in Utah below.
ii.
If the parties (NCP/CP) reside in different states, the order must
be registered in the non-requesting party’s state, or the state not requesting the review in accordance with Utah Code
81-8-611 which states:
“(1) If Section 81-8-613 does not apply, upon petition a tribunal
of this state may modify a child support order issued in another state which is
registered in this state if, after notice and hearing, the tribunal finds that:
(a) the following requirements are met:
(i) neither the child, nor the obligee
who is an individual, nor the obligor resides in the issuing state;
(ii) a petitioner who is a nonresident of this state seeks
modification; and
(iii) the respondent is subject to the personal jurisdiction of
the tribunal of this state. . . ”
Registering the order in the non-requesting state prohibits the
party requesting the modification from having an unfair advantage by seeking
the modification in his/her own state. After the order is registered, the
non-requesting state is able to review and modify the
order, if appropriate. If the registering state does not modify the order it does not gain CEJ, and the order is still
recognized as the controlling order for prospective enforcement.

EXAMPLE 1: CP applies for IV-D services in the state of Utah and
requests a modification. Take the actions listed
below.
a.
Determine the
appropriate state to review and, if appropriate,
modify the order – Because there is only one order (California order), it
is the controlling order. However, California has lost CEJ because both the
parties (NCP and CP) and the child have moved from the
state. The NCP and CP do not want California to continue to exercise its
jurisdiction to modify; therefore, California cannot modify its order. The
order must be registered for modification in another state. Since the CP
requested the modification, the order must be registered for modification in
the non-requesting state (Colorado) that has jurisdiction over the NCP. This
ensures that the tribunal conducting the modification has jurisdiction over the
parties (NCP and CP). Colorado has personal jurisdiction over the NCP and the
CP voluntarily submits to the jurisdiction of Colorado by requesting the
modification.
b.
Initiate
registration of the order for modification.
i.
Prepare an intergovernmental transmittal requesting that Colorado
register the order for modification. The transmittal packet includes the
following intergovernmental forms:
A.
Child Support Enforcement Transmittal #1 – Initial Request;
B.
Uniform Support Petition;
C.
General Testimony – the general testimony must first be sent to
the applicant for completion; and,
D.
Registration Statement.
ii.
Include two
copies of the California order (one certified) and an updated arrears
calculation.
iii.
Send a copy
of the intergovernmental packet to the Central Imaging Unit.
EXAMPLE 2: CP applies for IV-A services in Utah. The CP and her
child are approved for IV-A benefits and the IV-A case
is opened in ORSIS. In May 2007, the case is listed on the 3 Yr Review QMF
report. Take the actions listed below:
1.
Determine
if the case qualifies for the mandatory three-year review – Because the CP
and child are receiving IV-A cash assistance in Utah, the child in the order
will not emancipate within one year, and the order was issued more than three
years ago; the case does qualify for the three-year mandatory review.
2.
Determine
the appropriate state to review and, if appropriate, modify the order –
Because there is only one order (California order), it is the controlling
order. However, California has lost CEJ because both the parties (NCP and CP)
and the child have moved from the state. The NCP and
CP do not want California to continue to exercise its jurisdiction to modify;
therefore, California cannot modify its order. The order must be registered for
modification in another state. Since Utah is the requestor, the order must be
registered for modification in the non-requesting state (Colorado) that has
jurisdiction over the payor. This ensures that the tribunal conducting the
modification has jurisdiction over the parties (NCP and CP). Colorado has
personal jurisdiction over the NCP, and the CP submits to the Colorado’s
jurisdiction upon completion of the intergovernmental referrals.
3.
Initiate
registration of the order for modification.
1.
Prepare an intergovernmental transmittal
requesting that Colorado register the order for modification. The transmittal
packet includes the following intergovernmental forms:
1.
Child Support Enforcement Transmittal #1 –
Initial Request;
2.
Uniform Support Petition;
3.
General Testimony – The general testimony must
first be sent to the applicant for completion. Include the appropriate return
envelope for your office (yellow envelope or office self-addressed) to avoid
having the certified copy imaged. The return envelope
with the completed QIGT will be returned directly to the assigned agent without
first being imaged;
4.
Letter of Transmittal Requesting Registration;
5.
Child Support Agency Confidential Information
form; and,
6.
Personal Information Form for UIFSA.
2. Include two copies of the California order (one certified) and an updated arrears calculation.
A. Send a copy of the portions of the intergovernmental packet identified in the Forward Files Indices to the CIU to be imaged.
iii.
Send the original intergovernmental packet to
the Colorado CRU.
Example 3: CP applies for IV-D services in the state
of Utah and requests enforcement. An intergovernmental referral is sent to
Colorado requesting enforcement of the California order. Colorado takes the
actions listed below:
1.
Decide
whether administrative enforcement is appropriate – Upon receipt of the
intergovernmental documents, Colorado must first decide if administrative
enforcement is appropriate prior to registration of the order for enforcement. Because
the NCP is self-employed and has already ignored a previous income-withholding
request initiated by the state of Utah, Colorado determines that it is unlikely
that he will honor an administrative income withholding order from them.
2.
Register
the out-of-state order – Colorado registers the California order. As part
of the registration, the NCP is notified. Upon receipt of the notification, the
NCP sends a request for a modification of the order.
3.
Determine
the appropriate state to review and, if appropriate, modify the order –
Because there is only one order (California order), it is the controlling
order. However California has lost CEJ because both
the parties (NCP and CP) and the child have moved from the state. The NCP and
CP do not want California to continue to exercise its jurisdiction to modify;
therefore, California cannot modify its order. The order must be registered for
modification in another state. Since the NCP requested the modification, the
order must be registered for modification in the non-requesting state (Utah)
having jurisdiction over the CP. This ensures that the tribunal conducting the
modification has jurisdiction over the parties (NCP and CP). Utah has personal
jurisdiction over the CP and the NCP voluntarily submits to the jurisdiction of
Utah by requesting the modification.
4.
Initiate
registration of the order for modification – Colorado must:
i. Prepare an intergovernmental transmittal requesting that Utah register the order for modification. The transmittal packet must include the following federal forms:
A.
Child Support Enforcement Transmittal #1 –
Initial Request;
B.
Uniform Support Petition;
C.
General Testimony;
D.
Letter of Transmittal Requesting Registration;
E.
Child Support Agency Confidential Information
form; and,
F.
Personal Information Form for UIFSA.
ii.
Include the following:
A. Two copies of the California order (one certified); and,
B. An updated arrears calculation.
ii. Mail the intergovernmental packet to the Utah CRU.
5. Utah is responsible to review and, if appropriate, adjust the support order.
6. Colorado continues to enforce the order.
Procedures –
Conducting the Review
If Utah is
responsible for conducting the review and adjustment, if appropriate, follow
the procedures below:
1.
Follow
Utah’s normal review and adjustment procedures.
2.
If needed, request the assistance of another state in obtaining
information to assist with the review and adjustment, in accordance with Utah
Code 81-8-210, which states:
“(1) A tribunal of this state exercising
personal jurisdiction over a nonresident in a proceeding under this chapter,
under other law of this state relating to a support order, or recognizing a
foreign support order may:
(a)
receive evidence from outside this state in accordance with Section 81-8-316;
(b)
communicate with a tribunal outside this state in accordance with Section
81-8-317, and
(c)
obtain discovery through a tribunal outside this state in accordance with
Section 81-8-318.
(2) In
all other respects, Part 3, Civil Provisions of General Application, Part 4,
Establishment of Support Order or Determination of Parentage, Part 5,
Enforcement of Support Order Without Registration, and Part 6, Registration,
Enforcement, and Modification of Support Order, do not apply and the tribunal
shall apply the procedural and substantive law of this state.”
a.
Utah Code 81-8-317 states:
“(1) A tribunal of this state may communicate
with a tribunal outside this state in a record, or by telephone, electronic
mail, or other means, to obtain information concerning the laws, the legal
effect of a judgment, decree, or order of that tribunal, and the status of a
proceeding.
(2) A
tribunal of this state may furnish similar information by similar means to a
tribunal outside this state.”
b.
Utah Code 81-8-318 states:
“A tribunal of this state may:
(1) request a tribunal outside this state to assist in obtaining
discovery; and
(2) upon request, compel a person over whom it has jurisdiction to
respond to a discovery order issued by a tribunal outside this state.”
The CEJ tribunal cannot require the non-resident party’s physical
presence in a modification proceeding and must accept evidence via a telephone,
telecopier, and similar means that do not provide an original record.
To obtain the needed information from the other state, send the
“Child Support Enforcement Transmittal #3, Assistance/Discovery.”
3.
If the order
is not a Utah order, only modify the child support and/or medical support
provisions in accordance with Utah Code
81-8-611(3). If the order is from another state and all the parties
reside in Utah, you must complete the “Child Support Enforcement Intrastate
Transmittal – Modification/Registration” as part of the AGO referral packet.
Modification
of an Out-of-State Order When all Parties Reside in Utah
If the
controlling order was issued by another state and all the parties (NCP, CP and
child[ren]) reside in Utah, the order may be registered in the Utah courts for
purposes of modification, if appropriate, in accordance with Utah Code 81-8-613
which states:
“(1) If all of the parties who are individuals reside in this
state and the child does not reside in the issuing state, a tribunal of this
state has jurisdiction to enforce and to modify the issuing state's child
support order in a proceeding to register that order.”
Once the
order is registered in Utah, in accordance with Utah Code 81-8-611, it is
subject to the same requirements, procedures and defenses that apply to a modification of an order issued by this state, as follows:
“(2) Modification of a
registered child support order is subject to the same requirements, procedures,
and defenses that apply to the modification of an order issued by a tribunal of
this state and the order may be enforced and satisfied in the same manner.”
Utah Code
81-8-611 states:
“(3) (a) A tribunal of this
state may not modify any aspect of a child support order that may not be
modified under the law of the issuing state, including the duration of the
obligation of support.
(b) If two or more tribunals have issued child support orders
for the same obligor and same child, the order that controls and shall be so
recognized under Section 81-8-207 establishes the aspects
of the support order which are nonmodifiable.”
Specifically,
“duration of the obligation of support” may not be modified under an issuing
state’s law. Utah Code 81-8-611 states that in a proceeding to modify a child
support order, the law of the state that issued the initial controlling order
governs the duration of support, as follows:
“(4) (a) In a proceeding to
modify a child support order, the law of the state that is determined to have
issued the initial controlling order governs the duration of the obligation of
support.
(b) The obligor's fulfillment of the duty of support
established by that order precludes imposition of a further obligation of
support by a tribunal of this state."
NOTE: The
“initial controlling order” is not the first order issued. It is the order determined to be the controlling order.
The initial controlling order established and locks in duration. The
controlling order can be modified many times, but duration remains the same.
EXAMPLE:
w
1990 – NCP and CP get divorced in State A.
§
Duration of the support is age 18.
w
1992 – NCP moves to State B.
§
State B issues a Uniform Reciprocal Enforcement of Support Act
(URESA) order;
§
Duration of support is age 21.
w
2001 – State B’s order is determined to be the initial controlling
order.
§
Duration of support is “locked in” at age 21.
Once the NCP
has fulfilled the support duty under the controlling order, a tribunal cannot
impose a further support obligation; e.g., establishing a new support order.
After the
registration order is modified, the state of Utah:
1.
Assumes CEJ over the order in accordance with Utah Code 81-8-611, which states:
“(5) On issuance of an
order by a tribunal of this state modifying a child support order issued in
another state, the tribunal of this state becomes the tribunal of continuing,
exclusive jurisdiction.”
2.
Sends the required certified copy of the order in accordance with Utah
Code 81-8-614,
which states:
“(1) Within 30 days
after issuance of a modified child support order, the party obtaining the
modification shall file a certified copy of the order with the issuing tribunal
that had continuing, exclusive jurisdiction over the earlier order, and in each
tribunal in which the party knows the earlier order has been registered.
(2) A party who obtains the order and fails to file a
certified copy is subject to appropriate sanctions by a tribunal in which the
issue of failure to file arises.
(3) The failure to file does not affect the validity or
enforceability of the modified order of the new tribunal having continuing, exclusive jurisdiction.”
3.
Enforce the order as if the order had been issued by the State of
Utah in accordance with Utah Code 81-8-610, which states:
“A tribunal of this
state may enforce a child support order of another state registered for
purposes of modification, in the same manner as if the order had been issued by
a tribunal of this state, but the registered support order may be modified only
if the requirements of Section 81-8-611 or 81-8-613 have been met.”
NOTE:
If another state assumes CEJ over a Utah order for purposes of modification and
you receive a copy of the modified order, you must honor the order. Do not
attempt to re-modify the Utah order unless Utah can assume CEJ in accordance
with Utah Code 81-8-205. Make all appropriate changes to ORSIS based on the new modified
order and ensure that a copy of the order has been imaged into Content Manager
for the case along with the original order. For more clarification on
recognition of an order modified in another state, refer to subsection
Recognition and Enforcement of an Order Modified in Another State below.
Recognition
and Enforcement of an Order Modified in Another State
Utah Code
81-8-612 states that if an order is issued by a state and subsequently modified
by another state in accordance with UIFSA that order must be recognized and may
be enforced, as follows:
“If a child support order issued by a tribunal of this state is
modified by a tribunal of another state that assumed jurisdiction in accordance
with the Uniform Interstate Family Support Act, a tribunal of this state:
(1) may enforce the tribunal’s order that was modified only as to
arrears and interest accruing before the modification;
(2) may provide appropriate relief for violations of the tribunal’s
order which occurred before the effective date of the modification; and
(3) shall recognize the modifying order of the other state, upon
registration, for the purpose of enforcement.”
Jurisdiction
to Modify a Foreign Support Order
A U.S.
tribunal may modify a foreign support order when a tribunal of the foreign
country or political subdivision would have jurisdiction to modify its order
under UIFSA, but under the law or procedures of that foreign country, the
tribunal will not or may not exercise that jurisdiction to modify. For example,
some foreign countries have a requirement that the parties be physically
present in order to sustain a modification of child
support but are lacking the authority to compel a party residing outside of the
borders of the country to appear. In this situation, a U.S. tribunal may assume
modification jurisdiction and bind all individuals subject to its personal
jurisdiction in accordance with Utah Code 81-8-615 which states:
“(1) Except as otherwise provided in Section 81-8-711, if a
foreign country lacks or refuses to exercise jurisdiction to modify its child
support order pursuant to its laws, a tribunal of this state may assume
jurisdiction to modify the child support order and bind all individuals subject
to the personal jurisdiction of the tribunal whether or not the consent to
modification of a child support order otherwise required of the individual in
accordance with Section 81-8-611 has been given or whether the individual
seeking modification is a resident of this state or of the foreign country.
(2) An order issued by a tribunal of this state modifying a
foreign child support order in accordance with this section is the controlling order.”
Consent to
modify that is otherwise required under Utah Code 81-8-611 is not necessary nor
does it matter whether the individual seeking modification is a resident of the
U.S. or of the foreign country or political subdivision. Once an order is
issued under this section, it is the controlling order.
Utah Code
81-8-616 provides:
“(1) A party or child support services agency seeking to modify,
or to modify and enforce, a foreign child support order not under the
convention may register that order in this state under Sections 81-8-601
through 81-8-608 if the order has not been registered.
(2) A petition for modification may be filed at the same time as a
request for registration, or at another time.
(3) The petition shall specify the grounds for modification.”
