Consumer Legal Issue
I have primary physical custody of my two children and we have lived in Florida for 6 years. Their biological mother lives in Pennsylvania and the children visit her about 30 days per year. When we all lived in PA years ago, we each claimed one child on our taxes, but there is no current court order or signed agreement addressing tax dependency. There is a relocation order, but it does not specifically address tax claims and says the custody order would “remain in effect,” even though the living arrangement changed when we moved. The biological mother still wants to claim one child as a dependent, and I want to know.
No we only have an old court order from when we lived in the same state.
Attorney Answer
Unless you sign IRS Form 8332 (or an equivalent signed declaration), the biological mother cannot lawfully claim either child — and no court order can take the place of that signature. Federal tax law's custodial-parent default follows where the children actually sleep, and that favors you.
This is a matter of federal law, not Florida law. Under the Internal Revenue Code, the custodial parent — the parent with whom a child resides the greater number of nights during the year — has the right to claim that child as a dependent for tax benefits such as the child tax credit, unless that parent signs Form 8332 releasing the claim to the other parent. A court order is not a substitute for that signature: under Treas. Reg. § 1.152-4(e)(1)(ii), which implements I.R.C. § 152(e), "[a] court order or decree or a separation agreement may not serve as a written declaration" for any declaration executed after July 2, 2008. So even a Pennsylvania order squarely awarding her one child's dependency claim would not let her put that child on a return without your signed Form 8332. (The dependency exemption deduction itself is currently zero under federal law, though the related credits still follow this rule.) One nuance worth flagging: the relocation order's statement that the "custody order remains in effect" is ambiguous about whether it also carries forward the original agreement you and the mother had to split dependency claims when you both lived in the same state. A family court could still hold you to that old tax-sharing term independent of what the IRS's physical-custody default says — but its remedy would be to order you to sign a Form 8332 (and enforce that order against you), not to let her claim a child without one.
What you can do:
1. Confirm with the issuing family court or an attorney whether the original tax-sharing term survived the relocation order.
2. Do not sign a new Form 8332 unless a court order or clear written agreement requires it.
3. Keep records of the children's actual nights of residence with you in case the IRS needs to verify custodial status.
4. If both parents claim the same child, expect a rejected e-file, follow-up IRS correspondence to both of you, and possible penalties for whichever claim is found improper.
Relevant Case Law
Ceilia Abramovic v. Dan Abramovic, 188 So. 3d 61 (2016) — District Court of Appeal of Florida
The custodial parent presumptively is entitled to the [tax] exemptions but may release them to the noncustodial parent.
It states the rule the answer rests on: the parent the children live with holds the dependency claim unless that parent releases it.

Frequently Asked Questions
Who has the right to claim a child as a tax dependent after parents live in different states?
Under federal tax law, the parent with whom the child resides the greater number of nights during the year is generally treated as the custodial parent for dependency purposes, absent a signed release.
Does a state custody order automatically control which parent claims a child on federal taxes?
Not necessarily, federal tax rules generally follow physical residency by default, and a parent must sign a specific IRS release form to shift that right to the other parent, regardless of what a custody order says.
What happens if both parents claim the same child on their taxes?
Generally this results in a rejected electronic filing, follow-up correspondence from the IRS to both parents, and possible penalties for whichever claim is ultimately found improper.
