How Parental Responsibility Works When Parents Live in Different States

Parents move. Sometimes they moved before the case ever started. Sometimes one parent has been in Florida the entire time while the other has been in New York, Texas, or California since the child was born. When parents live in different states, every parental responsibility case carries an additional question on top of the merits: jurisdiction. Which state’s court has the authority to even decide?

Get this wrong and the merits never matter. Filing in the wrong state, in the wrong order, or failing to respond properly to the other parent’s filing in the right state can cost months of progress and frequently the case itself. Below is how Florida handles interstate parenting cases, the framework it operates under, and the practical decisions that determine where you should file — and where you should not.

The Governing Law: The UCCJEA

Forty-nine states (every state but Massachusetts, which has its own analogous statute) have adopted the Uniform Child Custody Jurisdiction and Enforcement Act — the UCCJEA. Florida codified it in Chapter 61, Part II of the Florida Statutes (§§ 61.501–61.542). The UCCJEA’s job is to ensure only one state at a time has jurisdiction over a child custody matter, and that orders from one state are recognized and enforced by the others.

The UCCJEA replaced an older patchwork — the UCCJA, the Parental Kidnapping Prevention Act (which is still federal law and still relevant) — and produced a hierarchy of jurisdictional bases that Florida courts apply in a defined order. Filing in the wrong order, or failing to plead the basis correctly, is one of the most common reasons interstate cases get dismissed.

The Concept That Drives Everything: Home State

The single most important UCCJEA concept is home state. Under § 61.503(7), a child’s home state is the state in which the child has lived with a parent (or person acting as a parent) for at least six consecutive months immediately before the commencement of the custody proceeding. For a child under six months old, the home state is the state where the child has lived since birth.

Three things to internalize:

• Temporary absences do not break home state. A vacation, a summer visit with the other parent, a hospital stay — none of these reset the six-month clock. Florida looks at where the child resides, not where the child happens to be on any given day.
• Home state runs to the date of filing. A parent who moves to Florida on January 1 cannot establish Florida home state until July 1, regardless of how settled life feels by April.
• Home state is the dominant test. The other UCCJEA bases for jurisdiction only kick in when no state qualifies as home state.

The Jurisdictional Hierarchy

Under § 61.514, a Florida court can take initial child custody jurisdiction in a case involving multiple states only on one of four bases, applied in this order:

1. Florida is the child’s home state on the date the proceeding commences, or Florida was the child’s home state within six months before the proceeding commenced and the child is now absent from Florida but a parent (or person acting as parent) still lives in Florida.
2. No state qualifies as home state under (1) — or every home state has declined jurisdiction in favor of Florida — and the child and at least one parent (or person acting as parent) have a significant connection with Florida beyond mere physical presence, and substantial evidence concerning the child’s care, protection, training, and personal relationships is available in Florida.
3. All other states with potential jurisdiction have declined in favor of Florida on the grounds that Florida is the more appropriate forum.
4. No other state has jurisdiction under any of the above.

Home state under (1) is the dominant test. If the child has lived in Texas for the last twelve consecutive months, Florida is not the home state — even if the Florida parent files first, even if Florida is the more convenient forum, and even if both parents agree to litigate here.

Initial Cases: Where Should You File?

If Your Child Has Lived in Florida for at Least Six Consecutive Months

Florida is almost certainly the proper forum. File here. Make sure your petition pleads the jurisdictional basis explicitly — under § 61.522, parties initiating custody proceedings must submit a UCCJEA Affidavit (Florida Supreme Court Approved Family Law Form 12.902(d)) disclosing the child’s residences for the prior five years and any other custody proceedings in any state.

If Your Child Recently Moved to Florida

If the child has been here less than six months, the prior state is likely still the home state — or, under § 61.514(1)(a)2, Florida may have a basis if Florida was the child’s home state within the last six months and a parent still lives here. Outside that narrow exception, filing in Florida prematurely is risky. The case can be dismissed for lack of jurisdiction, and while you wait, the other parent may file in the actual home state and capture the case.

If Your Child Has Lived in Multiple States in the Last Six Months

Map the timeline carefully and conservatively. The home state is whichever state had the child for the most recent six consecutive months. If the timeline is genuinely fragmented — a child split between two homes in two states for several months each — no state may currently qualify as home state, in which case § 61.514(1)(b) (significant-connection jurisdiction) becomes the analysis.

If You Are Fleeing Domestic Violence

The UCCJEA includes emergency jurisdiction provisions under § 61.517. A Florida court can enter temporary protective orders even when Florida is not the home state if (a) the child is present in Florida and (b) protection is necessary because the child, or a sibling or parent of the child, is subjected to or threatened with mistreatment or abuse. These orders are temporary — the home state still has primary jurisdiction over the underlying parenting determination — but they can buy time and safety while the longer-term case is brought in the home state.

Emergency jurisdiction is heavily fact-dependent and frequently litigated. The Florida court entering the temporary order is required to communicate with any home-state court already exercising jurisdiction under § 61.517  and the temporary order has a defined lifespan tied to action in the home state.

Continuing Jurisdiction: Once Florida Has the Case

Once a Florida court enters an initial parenting order, it generally retains exclusive, continuing jurisdiction under § 61.515. That means even if the child later moves to another state, the Florida court keeps jurisdiction over modifications — until either:

• A Florida court determines that neither the child, the child and a parent, nor the child and a person acting as a parent has a significant connection with Florida and that substantial evidence concerning the child is no longer available in Florida; or
• A Florida or out-of-state court determines that the child, both parents, and any person acting as a parent no longer reside in Florida.

This is why parents who move out of Florida sometimes find themselves still litigating in Miami or Fort Lauderdale long after the move. Continuing jurisdiction does not automatically transfer when the family physically leaves — somebody has to ask the court to relinquish it, and the analysis under § 61.515 has to be made.

A related provision, § 61.520, allows a Florida court to decline jurisdiction on grounds of inconvenient forum even when it has jurisdiction, after considering factors like the location of the child, the parents, the witnesses, and the relevant evidence. This is the channel through which interstate cases sometimes get appropriately transferred when the family’s life has fully relocated to another state.

Modification Cases: Which State Decides?

Under § 61.516, a Florida court generally cannot modify another state’s parenting order unless either:

• Florida is now the child’s home state (or has another proper basis under § 61.514) and the original-state court has determined it no longer has exclusive, continuing jurisdiction or that Florida would be a more convenient forum, or
• A court determines that the child, both parents, and any person acting as a parent do not presently reside in the original state.

This is a frequent source of confusion. A parent who moves to Florida with the child, lives here for a year, and files to modify the original out-of-state order in Florida courts may still find Florida lacks jurisdiction if the original-state court has not relinquished it. The proper move in many of these cases is to first ask the original court to decline jurisdiction in favor of Florida — not to file in Florida directly.

Enforcement: The Other Half of the UCCJEA

Even when Florida cannot modify another state’s order, Florida will enforce one. Under §§ 61.526–61.528, a parenting order from another state can be registered in Florida and treated as if it were a Florida order. Once registered, Florida courts can enforce it through contempt, expedited enforcement under § 61.529, pickup orders under § 61.530, and (in extreme cases) law enforcement assistance to recover a child.

For Florida parents whose ex has moved out of state with a Florida order in place, this matters in reverse: Florida orders are registrable and enforceable in the new state through that state’s UCCJEA enforcement provisions.

A Practical Decision Tree

Use this as a starting point — every interstate case has nuances that require professional judgment, but the framework is consistent.

Has the child lived in Florida for the last six consecutive months?

• Yes → Florida is likely the home state. File in Florida.
• No → Continue.

Was Florida the child’s home state within the last six months, and does a parent still live here?

• Yes → Florida likely has home-state jurisdiction under § 61.514(1)(a)2. Florida is generally the proper forum.
• No → Continue.

Where has the child lived for the most recent six consecutive months?

• Identifiable home state → That state has jurisdiction. File there, not in Florida.
• No identifiable home state → Significant-connection jurisdiction under § 61.514(1)(b) may apply. Counsel needed.

Is there an existing parenting order in another state?

• Yes, and you want to modify it → § 61.516 analysis. Often the proper move is in the original state.
• Yes, and you want to enforce it in Florida → Register under § 61.526. Florida will enforce.

Is there a domestic violence emergency?

• Yes, and the child is in Florida → § 61.517 emergency jurisdiction may apply for temporary orders. The underlying case still belongs in the home state.

Common Interstate Mistakes

Filing in the Wrong State

Filing in Florida when the home state is elsewhere often hands the other parent an advantage. They can move to dismiss your case, file in the proper state, and put you in a defensive posture from day one. Worse, you may have spent legal fees on a case that never had jurisdiction.

Moving the Child Without Authorization

If a parenting order is already in place, taking the child across state lines without the other parent’s consent or court permission can constitute a violation of the order, the Florida relocation statute (§ 61.13001), the federal Parental Kidnapping Prevention Act, or — in international cases — the Hague Convention.

Assuming “My State” Means “My Court”

Living in Florida does not mean Florida courts have jurisdiction over your child. Jurisdiction follows the child, not the parent.

Ignoring the Other State’s Order

If another state has a valid parenting order, Florida will enforce it. Treating a move to Florida as a fresh start almost always backfires.

Failing to Submit the UCCJEA Affidavit

The UCCJEA Affidavit (Form 12.902(d)) is required in every Florida case where custody is at issue and disclosure of the child’s residences and other custody proceedings is mandatory. Failing to file it correctly invites motion practice, dismissal, or worse — sanctions.

A Note on International Cases

International custody disputes are governed primarily by the Hague Convention on the Civil Aspects of International Child Abduction, not the UCCJEA. The Hague analysis is significantly different — focused on wrongful removal or retention from a child’s habitual residence — and the remedies are different too. In a community as internationally connected as Miami-Dade, international parenting cases come up often, and the wrong analytical framework produces the wrong strategy. Hague cases require attorneys with specific experience in international child abduction proceedings.

Frequently Asked Questions

What is the UCCJEA in Florida?

The UCCJEA is the Uniform Child Custody Jurisdiction and Enforcement Act, codified in Florida at §§ 61.501–61.542. It governs which state’s courts have authority over a child custody matter and how custody orders from one state are recognized and enforced by another.

My ex moved to Florida with our child. Can they file here right away?

Generally not. They typically must wait until Florida becomes the child’s home state — six consecutive months of residence here. Filing earlier risks dismissal. There is a narrow exception under § 61.514(1)(a)2 if Florida was the home state within the prior six months and a parent still lives here.

If I have a Florida order and my ex moves to another state, do I have to follow them there to modify it?

Often no. Florida usually retains exclusive, continuing jurisdiction under § 61.515 even after a move. Whether the case can be transferred to the new state depends on a separate analysis under § 61.520 (inconvenient forum) and the connections that remain in Florida.

Can two states issue custody orders for the same child?

Under the UCCJEA, no — not validly. The first proper court has jurisdiction, and the second is required to defer or decline under §§ 61.519. In practice, jurisdictional disputes do happen, and they get resolved through court-to-court communication under § 61.510.

What is “home state” under the UCCJEA?

Under § 61.503(7), a child’s home state is the state where the child has lived with a parent or person acting as a parent for at least six consecutive months immediately before the custody proceeding starts. For a child under six months old, the home state is where the child has lived since birth. Temporary absences do not break home state.

What is emergency jurisdiction in Florida?

Under § 61.517, a Florida court can enter a temporary order even when Florida is not the home state, if the child is present in Florida and protection is needed because the child, a sibling, or a parent has been or is threatened with mistreatment or abuse. The order is temporary and the underlying case still belongs in the home state.

Do I need a Florida lawyer if my case is in another state?

If your case is filed in another state, you need counsel admitted in that state. If you are in Florida and need to enforce or register an out-of-state order, defend against an out-of-state filing, or contest the other parent’s choice of forum, a Florida family law attorney is generally necessary.
