In This TopicIdaho Child Custody Jurisdiction (UCCJEA)Topic 2 of 6: Continuing Jurisdiction

After a court makes a custody order, families move, children grow, and circumstances change. Idaho’s Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) decides which state’s court may later change, or “modify,” that order. The court that made the order usually keeps control of it, which the Idaho Code calls “exclusive, continuing jurisdiction” (Idaho Code § 32-11-202(a)).

This page explains when an Idaho court keeps that control, when it ends, and when an Idaho court may change a custody order made in another state. It matters to any parent or caregiver who wants to change an existing custody or visitation order after someone has moved.

What Counts as a “Modification”

A “modification” is a child custody determination that changes, replaces, supersedes, or is otherwise made after a previous determination concerning the same child, whether or not it is made by the court that made the previous determination (Idaho Code § 32-11-102(k)). A “child custody determination” includes permanent, temporary, initial, and modification orders about legal custody, physical custody, or visitation, but not orders about child support or other money obligations (§ 32-11-102(c)).

An Idaho custody determination made with jurisdiction is conclusive as to all decided issues of law and fact for the persons it binds, except to the extent it is modified (Idaho Code § 32-11-106). So the question of which court may modify an order is important.

When an Idaho Court Keeps Exclusive, Continuing Jurisdiction

An Idaho court that made a child custody determination consistent with Idaho Code § 32-11-201 (initial jurisdiction) or § 32-11-203 (jurisdiction to modify) has exclusive, continuing jurisdiction over the determination (Idaho Code § 32-11-202(a)). The only exception is temporary emergency jurisdiction under Idaho Code § 32-11-204 (§ 32-11-202(a)). That jurisdiction lasts until one of two things happens (§ 32-11-202(a)(1)-(2)):

1. Connection with Idaho is lost. An Idaho court determines that neither the child, nor the child and one (1) parent, nor the child and a person acting as a parent have a significant connection with Idaho, and that substantial evidence is no longer available in Idaho concerning the child’s care, protection, training, and personal relationships (§ 32-11-202(a)(1)).
2. Everyone has left Idaho. An Idaho court or a court of another state determines that the child, the child’s parents, and any person acting as a parent do not presently reside in Idaho (§ 32-11-202(a)(2)).

Note the difference between the two. Under the first, only an Idaho court makes the determination (§ 32-11-202(a)(1)). Under the second, either an Idaho court or a court of another state may make it (§ 32-11-202(a)(2)).

A “person acting as a parent” is someone other than a parent who has, or recently had, physical custody of the child and who has been awarded legal custody by a court or claims a right to legal custody under Idaho law (Idaho Code § 32-11-102(m)). See Home State Jurisdiction for the full definition.

After Exclusive, Continuing Jurisdiction Ends

An Idaho court that made a custody determination but no longer has exclusive, continuing jurisdiction may modify that determination only if it has jurisdiction to make an initial determination under Idaho Code § 32-11-201 (Idaho Code § 32-11-202(b)). This means the Idaho court must again meet one of the grounds for initial jurisdiction described on the Home State Jurisdiction page (§ 32-11-202(b)).

Changing Another State’s Custody Order in Idaho

Except for temporary emergency jurisdiction, an Idaho court may not modify a child custody determination made by a court of another state unless two conditions are both met (Idaho Code § 32-11-203).

First, the Idaho court must have jurisdiction to make an initial determination under Idaho Code § 32-11-201(a)(1) (home state) or § 32-11-201(a)(2) (significant connection) (§ 32-11-203). The other two initial grounds, in § 32-11-201(a)(3) and (a)(4), are not listed in § 32-11-203.

Second, one of the following must also be true (§ 32-11-203(a)-(b)):

• The court of the other state determines that it no longer has exclusive, continuing jurisdiction under Idaho Code § 32-11-202, or that an Idaho court would be a more convenient forum under Idaho Code § 32-11-207 (§ 32-11-203(a)); or
• An Idaho court or a court of the other state determines that the child, the child’s parents, and any person acting as a parent do not presently reside in the other state (§ 32-11-203(b)).

The inconvenient forum rules in Idaho Code § 32-11-207 are covered on the Declining Jurisdiction page.

Quick Comparison

Situation	What the Idaho Code says	Idaho Code
Idaho made the order and still has exclusive, continuing jurisdiction	The Idaho court keeps exclusive, continuing jurisdiction over the determination	§ 32-11-202(a)
Idaho made the order but lost exclusive, continuing jurisdiction	The Idaho court may modify only if it has jurisdiction to make an initial determination under § 32-11-201	§ 32-11-202(b)
Another state made the order	Idaho may modify only if it has initial jurisdiction under § 32-11-201(a)(1) or (2) and one of the conditions in § 32-11-203(a) or (b) is met	§ 32-11-203
Another state’s order is registered in Idaho	Idaho must recognize and enforce it, but may not modify it except in accordance with part 2 of the act	§ 32-11-306(b)
Emergency involving a child present in Idaho	Temporary emergency jurisdiction is an exception to these rules	§§ 32-11-202(a), 32-11-203, 32-11-204

Registration Does Not Allow Modification

A custody order from another state can be registered in Idaho. An Idaho court must recognize and enforce a registered determination of another state’s court, but may not modify it except in accordance with part 2 of the act, which contains the jurisdiction rules described above (Idaho Code § 32-11-306(b)). Registration is explained on the Registering and Enforcing Orders page.

An Idaho court that does not have jurisdiction to modify a custody determination may still issue a temporary order enforcing another state’s visitation schedule, or the visitation provisions of another state’s order that does not provide a specific visitation schedule (Idaho Code § 32-11-304(a)). If it makes an order of the second kind, it must specify a period it considers adequate for the petitioner to obtain an order from a court having jurisdiction under part 2 of the act. 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

In a case to modify a custody determination, the Idaho court must determine whether a proceeding to enforce the determination has been commenced in another state (Idaho Code § 32-11-206(c)). If one has, the Idaho court may (§ 32-11-206(c)(1)-(3)):

• Stay the modification case until the other state’s court enters an order enforcing, staying, denying, or dismissing the enforcement case;
• Enjoin the parties from continuing with the enforcement case; or
• Proceed with the modification under conditions it considers appropriate.

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

Other Rules That Apply to Modification Cases

• Limited immunity: a party to a custody case, including a modification case, is not subject to personal jurisdiction in Idaho for another case or purpose solely because the party participated in the case or was physically present to participate (Idaho Code § 32-11-109(a)).
• Declining jurisdiction: an Idaho court with jurisdiction may decline to exercise it at any time if it determines that it is an inconvenient forum and that a court of another state is a more appropriate forum (Idaho Code § 32-11-207(a)).
• Court communication: an Idaho court may communicate with a court in another state about a proceeding under the act (Idaho Code § 32-11-110(a)). If the parties are not able to take part in the communication, they must be given the opportunity to present facts and legal arguments before a decision on jurisdiction is made (§ 32-11-110(b)).
• Sworn information: each party must provide the information about the child’s residences and other cases required by Idaho Code § 32-11-209(a), and has a continuing duty to tell the court about any case that could affect the current one (§ 32-11-209(d)).

How I Can Help

I help parents and caregivers figure out whether an Idaho court can change an existing custody or visitation order, whether the order was made in Idaho or in another state. I look at where the child and each parent now live, what the original court has decided, and whether any other cases are pending, and explain how the Idaho Code applies.
