In This TopicIdaho Child Custody Jurisdiction (UCCJEA)Topic 5 of 6: Registering & Enforcing Orders

When a custody or visitation order comes from another state, Idaho’s Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), Title 32, Chapter 11 of the Idaho Code, gives two main tools: registering the order in Idaho and asking an Idaho court to enforce it. An Idaho court shall recognize and enforce another state’s child custody determination if that court exercised jurisdiction in substantial conformity with chapter 11, or the determination was made under factual circumstances meeting chapter 11’s jurisdictional standards, and the determination has not been modified in accordance with chapter 11 (Idaho Code § 32-11-303(a)).

A “child custody determination” is a judgment, decree, or other court order providing for legal custody, physical custody, or visitation, and it does not include an order relating to child support or other monetary obligation (Idaho Code § 32-11-102(c)). This page covers registration, expedited enforcement, warrants, fees, and appeals, and it matters both to people holding an out-of-state order and to people responding to one.

The Duty to Enforce and Other Remedies

An Idaho court may use any remedy available under other Idaho law to enforce a child custody determination made by a court of another state (Idaho Code § 32-11-303(b)). The remedies in part 3 of chapter 11 are cumulative and do not affect the availability of other remedies (§ 32-11-303(b)).

An Idaho court shall accord full faith and credit to an order issued by another state, consistent with chapter 11, that enforces a child custody determination by a court of another state (Idaho Code § 32-11-313). The exception is when that order has been vacated, stayed, or modified by a court having jurisdiction to do so under part 2 of chapter 11 (§ 32-11-313).

Registering an Out-of-State Order

A child custody determination issued by a court of another state may be registered in Idaho, with or without a simultaneous request for enforcement (Idaho Code § 32-11-305(a)). The person seeking registration sends the following to the office of the clerk of any district court in Idaho (§ 32-11-305(a)(1)-(3)):

• A letter or other document requesting registration;
• Two copies of the determination, including one certified copy, and a statement under penalty of perjury that, to the best of the person’s knowledge and belief, the order has not been modified; and
• Except as otherwise provided in § 32-11-209, the name and address of the person seeking registration and of any parent or person acting as a parent who has been awarded custody or visitation in the determination.

When it receives these documents, the registering court shall cause the determination to be filed as a foreign judgment, together with one copy of any accompanying documents and information, regardless of their form (Idaho Code § 32-11-305(b)(1)). The court shall also serve notice on the persons named in the request and give them an opportunity to contest the registration (§ 32-11-305(b)(2)).

The notice must state that a registered determination is enforceable as of the date of registration in the same manner as an Idaho order, that a hearing to contest its validity must be requested within 20 days after service of notice, and that failure to contest will result in confirmation and preclude further contest of any matter that could have been asserted (Idaho Code § 32-11-305(c)).

Contesting Registration

A person who wants to contest the validity of a registered order must request a hearing within 20 days after service of the notice (Idaho Code § 32-11-305(d)). At the hearing, the court shall confirm the registered order unless the person contesting registration establishes one of the following (§ 32-11-305(d)(1)-(3)):

• The issuing court did not have jurisdiction under part 2 of chapter 11;
• The determination has been vacated, stayed, or modified by a court having jurisdiction to do so under part 2 of chapter 11; or
• The person contesting was entitled to notice, but notice was not given in accordance with the standards of § 32-11-108 in the proceedings before the issuing court.

If no timely request for a hearing is made, the registration is confirmed as a matter of law, and the person requesting registration and all persons served must be notified of the confirmation (Idaho Code § 32-11-305(e)). Confirmation, whether by operation of law or after notice and hearing, precludes further contest of the order on any matter that could have been asserted at the time of registration (§ 32-11-305(f)).

Effect of a Registered Order

An Idaho court may grant any relief normally available under Idaho law to enforce a registered child custody determination made by a court of another state (Idaho Code § 32-11-306(a)). The court shall recognize and enforce, but may not modify, a registered determination except in accordance with part 2 of chapter 11 (§ 32-11-306(b)). For when Idaho may change another state’s order, see continuing jurisdiction and modification.

Expedited Enforcement

A petition to enforce under part 3 of chapter 11 must be verified (Idaho Code § 32-11-308(a)). Certified copies of all orders sought to be enforced, and of any order confirming registration, must be attached, and a copy of a certified copy may be attached instead of the original (§ 32-11-308(a)). The “petitioner” is the person seeking enforcement, and the “respondent” is the person against whom an enforcement proceeding has been commenced (Idaho Code § 32-11-102(n), (p)).

What the Petition Must State

• Whether the issuing court identified the jurisdictional basis it relied on and, if so, what it was (Idaho Code § 32-11-308(b)(1));
• Whether the determination has been vacated, stayed, or modified by a court whose decision must be enforced under chapter 11, and any other proceeding commenced that could affect the current one, such as domestic violence, protective order, termination of parental rights, or adoption proceedings, with the court, case number, and nature of each (§ 32-11-308(b)(2)-(3));
• The present physical address of the child and the respondent, if known (§ 32-11-308(b)(4));
• Any relief sought beyond immediate physical custody of the child and attorney’s fees, including law enforcement assistance (§ 32-11-308(b)(5)); and
• If the determination was registered and confirmed under § 32-11-305, the date and place of registration (§ 32-11-308(b)(6)).

Order to Appear and Fast Hearing

When the petition is filed, the court shall issue an order directing the respondent to appear in person, with or without the child, at a hearing, and may enter any order necessary to ensure the safety of the parties and the child (Idaho Code § 32-11-308(c)). The hearing must be held on the next judicial day after service of the order unless that date is impossible, in which case it must be held on the first judicial day possible (§ 32-11-308(c)). The court may extend the hearing date at the petitioner’s request (§ 32-11-308(c)).

Except as provided for warrants in § 32-11-311, the petition and order must be served, by any method authorized by Idaho law, on the respondent and any person who has physical custody of the child (Idaho Code § 32-11-309).

The order must state the time and place of the hearing and advise the respondent of what the court will order unless the respondent appears and establishes one of the defenses below (Idaho Code § 32-11-308(d)).

Defenses at the Hearing

Unless the court issues a temporary emergency order under § 32-11-204, if it finds the petitioner is entitled to immediate physical custody of the child, the court shall order that the petitioner may take immediate physical custody unless the respondent establishes a defense (Idaho Code § 32-11-310(a)). The available defenses depend on whether the order was registered and confirmed (§ 32-11-310(a)(1)-(2)):

Order not registered and confirmed	Order registered and confirmed under § 32-11-305
The respondent may show that: (A) the issuing court did not have jurisdiction under part 2; (B) the determination has been vacated, stayed, or modified by a court of a state having jurisdiction to do so under part 2; or (C) the respondent was entitled to notice, but notice was not given in accordance with § 32-11-108 in the issuing court (§ 32-11-310(a)(1)).	The respondent may show only that the determination has been vacated, stayed, or modified by a court of a state having jurisdiction to do so under part 2 (§ 32-11-310(a)(2)).

The court shall award the fees, costs, and expenses authorized under § 32-11-312, and may grant additional relief, including a request for the assistance of law enforcement officials, and set a further hearing on additional relief (Idaho Code § 32-11-310(b)).

If a party called to testify refuses to answer on the ground that the testimony may be self-incriminating, the court may draw an adverse inference from the refusal (Idaho Code § 32-11-310(c)). A privilege against disclosure of communications between spouses, and a defense of immunity based on the relationship of husband and wife or parent and child, may not be invoked in a part 3 proceeding (§ 32-11-310(d)).

Warrant to Take Physical Custody of a Child

Upon the filing of a petition to enforce, the petitioner may file a verified application for a warrant to take physical custody of the child if the child is immediately likely to suffer serious physical harm or be removed from Idaho (Idaho Code § 32-11-311(a)). The application must include the statements required for the petition by § 32-11-308(b) (§ 32-11-311(b)). A “warrant” is a court order authorizing law enforcement officers to take physical custody of a child (Idaho Code § 32-11-102(s)).

If the court, based on the testimony of the petitioner or another witness, finds that the child is imminently likely to suffer serious physical harm or be removed from Idaho, it may issue the warrant (Idaho Code § 32-11-311(b)). The petition must then be heard on the next judicial day after the warrant is executed unless that date is impossible, in which case on the first judicial day possible (§ 32-11-311(b)).

The warrant must recite the facts supporting the conclusion of imminent serious physical harm or removal, direct law enforcement officers to take physical custody of the child immediately, and provide for the child’s placement pending final relief (Idaho Code § 32-11-311(c)). The respondent must be served with the petition, warrant, and order immediately after the child is taken into physical custody (§ 32-11-311(d)).

The warrant is enforceable throughout Idaho (Idaho Code § 32-11-311(e)). If the court finds that a less intrusive remedy is not effective, it may authorize officers to enter private property to take the child, and if exigent circumstances require, it may authorize a forcible entry at any hour (§ 32-11-311(e)). The court may impose conditions on the child’s placement to ensure the appearance of the child and the child’s custodian (§ 32-11-311(f)).

Temporary Orders Enforcing Visitation

An Idaho court that does not have jurisdiction to modify a custody determination may still issue a temporary order enforcing a visitation schedule made by a court of another state (Idaho Code § 32-11-304(a)(1)). It may also enforce the visitation provisions of another state’s determination that does not provide for a specific visitation schedule (§ 32-11-304(a)(2)).

In the second situation, the order shall specify a period the court considers adequate for the petitioner to obtain an order from a court having jurisdiction under part 2 of chapter 11 (Idaho Code § 32-11-304(b)). The order remains in effect until an order is obtained from the other court or the period expires (§ 32-11-304(b)).

When Enforcement and Modification Cases Overlap

If an enforcement proceeding is commenced in Idaho and the court determines that a proceeding to modify the determination is pending in a court of another state having jurisdiction to modify under part 2, the Idaho court shall immediately communicate with that court (Idaho Code § 32-11-307). The enforcement proceeding continues unless the Idaho court, after consulting with the modifying court, stays or dismisses it (§ 32-11-307).

In the reverse situation, an Idaho court hearing a modification case shall determine whether an enforcement proceeding has been commenced in another state (Idaho Code § 32-11-206(c)). If one has, the court may stay the modification pending the other court’s order, enjoin the parties from continuing with the enforcement proceeding, or proceed with the modification under conditions it considers appropriate (§ 32-11-206(c)(1)-(3)). See declining jurisdiction for other rules on cases in two states.

Fees, Costs, and Expenses

The court shall award the prevailing party, including a state, necessary and reasonable expenses incurred by or on behalf of the party (Idaho Code § 32-11-312(a)). These include costs, communication expenses, attorney’s fees, investigative fees, expenses for witnesses, travel expenses, and child care during the course of the proceedings (§ 32-11-312(a)).

No award is made if the party from whom fees or expenses are sought establishes that the award would be clearly inappropriate (Idaho Code § 32-11-312(a)). The court may not assess fees, costs, or expenses against a state unless authorized by law other than chapter 11 (§ 32-11-312(b)).

Help From the County Prosecuting Attorney

In a case arising under chapter 11 or involving the Hague Convention on the Civil Aspects of International Child Abduction, the county prosecuting attorney may take any lawful action, including a proceeding under chapter 11 or any other available civil proceeding, to locate a child, obtain the return of a child, or enforce a custody determination (Idaho Code § 32-11-315(a)). This applies if there is (§ 32-11-315(a)(1)-(4)):

• An existing child custody determination;
• A request to do so from a court in a pending child custody proceeding;
• A reasonable belief that a criminal statute has been violated; or
• A reasonable belief that the child has been wrongfully removed or retained in violation of the Hague Convention on the Civil Aspects of International Child Abduction.

The prosecuting attorney acts on behalf of the court and may not represent any party (Idaho Code § 32-11-315(b)). At the prosecuting attorney’s request, a law enforcement officer may take any lawful action reasonably necessary to locate a child or a party and assist the prosecuting attorney (Idaho Code § 32-11-316). If the respondent is not the prevailing party, the court may assess against the respondent all direct expenses and costs incurred by the prosecuting attorney and law enforcement officers under these sections (Idaho Code § 32-11-317).

Appeals

An appeal may be taken from a final order in a proceeding under chapter 11, and the court shall make every effort to expedite the appeal (Idaho Code § 32-11-314). Unless the court enters a temporary emergency order under § 32-11-204, the enforcing court may not stay an order enforcing a child custody determination while the appeal is pending (§ 32-11-314).

Orders from foreign countries and Hague Convention return orders are addressed in separate sections of chapter 11 (Idaho Code §§ 32-11-105, 32-11-302); see international and tribal cases. For how Idaho courts decide custody in the first place, see Idaho child custody.

How I Can Help

If you have a custody or visitation order from another state, or someone is seeking to register or enforce one against you in Idaho, I can review the order and the Idaho Code requirements with you, help prepare registration documents or an enforcement petition, and help you assess whether any of the statutory defenses may apply. Because the Idaho Code sets a 20-day window to request a hearing contesting registration, timing matters. Request a consultation to discuss your situation.
