Interstate custody cases often feel less like one family-law case and more like a race between deadlines, geography, paperwork, and court authority. When parents live in different states—or when a child has recently moved—one of the first questions is not “Who is right?” It is which court gets to decide at all.
That question matters because interstate custody disputes are largely governed by the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), a uniform law designed to reduce conflicting custody orders, discourage forum shopping, and promote cooperation between courts in different states. Federal law also plays a role through the Parental Kidnapping Prevention Act (PKPA), which requires states to give full faith and credit to qualifying custody determinations from sister states. The Uniform Law Commission explains the UCCJEA here, and Cornell’s Legal Information Institute summarizes the federal statute here.
If a parent files in the wrong state, leaves out key facts, confuses an emergency order with long-term jurisdiction, or ignores an existing out-of-state order, the case can slow down fast. Hearings get postponed. Judges ask for more information. Competing filings appear. In some families, the delay becomes the whole story.
This post walks through seven jurisdiction mistakes that commonly stall interstate custody cases, why they matter, and what families often consider when the situation becomes urgent. If you want a broader overview of multi-state and cross-border custody rules, this plain-English breakdown of interstate and international custody issues can help frame the bigger picture.

The UCCJEA was built to avoid exactly the kind of chaos interstate parents fear: two states issuing conflicting orders, repeated relitigation, and children being moved across state lines in the middle of a dispute. Congress made similar findings in the PKPA, noting that inconsistent state practices had contributed to child seizures, concealment, conflicting orders, and expensive, time-consuming interstate litigation. The federal statute’s findings are summarized in 28 U.S.C. § 1738A.
In practical terms, a judge in State A may pause a case until the court determines:
That is why even a small filing mistake can produce weeks or months of delay.
The most common jurisdiction mistake is assuming that the child’s current location automatically controls.
Under the UCCJEA, the starting point in many initial custody cases is the child’s “home state,” generally the state where the child lived with a parent for at least six consecutive months immediately before the case began. A recent move usually does not erase the prior state’s authority overnight. The Uniform Law Commission’s UCCJEA materials and Cornell’s child custody overview both reflect that interstate custody jurisdiction usually turns on this home-state framework.
This is where many parents get tripped up. A child may now be enrolled in school in Texas, seeing a doctor in Texas, and sleeping in Texas every night—but if the family left Colorado only a few weeks ago, a Texas court may not be the right court for a long-term custody decision.
