The statute of limitations for family law claims is not a single deadline but a patchwork of windows that depend on what you are asking a court to do. Spousal maintenance must usually be raised before the divorce decree is signed. Annulments run anywhere from 90 days to several years, or no deadline at all, depending on the ground. Reopening a property division typically gives you one to two years. Child support arrears, by federal rule, never expire as modifiable debt. The common thread: once your window closes, the money, property, or marital status question is settled for good.
Spousal Maintenance Must Be Raised Before the Decree
In most states, you must ask for spousal maintenance (also called alimony or spousal support) while your divorce case is still open. If the judge signs a final decree that does not include a maintenance award, the opportunity is almost always gone. Courts treat the final judgment as a full settlement of financial obligations between the spouses, and reopening it to add a support claim you never raised is extraordinarily difficult.
The procedural window here is not a calendar deadline like “two years from filing.” It is the lifespan of the case itself. Once the case closes, the window shuts. Some states let you request temporary support while the divorce is pending through a pendente lite motion, and that interim award can be made retroactive to the date you filed the request, which rewards filing early.
Modifications to an existing maintenance order follow a separate set of rules. If the decree already includes a support award, either spouse can usually petition to increase, reduce, or terminate payments based on a significant change in circumstances such as job loss or a health crisis. But this only works when a maintenance provision already exists. Starting a brand-new maintenance claim after the case is closed, when the decree is silent on support, is a fundamentally different request, and most courts will not entertain it.
Annulment Deadlines Depend on the Ground
Annulment deadlines turn almost entirely on the legal ground you are using to challenge the marriage, and the critical distinction is between void and voidable marriages.
A void marriage, such as one involving bigamy or a close blood relationship, was never legally valid. No statute of limitations applies. You can challenge it at any time, even decades later, because the law treats the marriage as though it never existed.
Voidable marriages have a legal defect — fraud, duress, incapacity, or inability to consummate — but remain valid unless a court declares otherwise. Filing windows for voidable marriages are tight, and continuing to live together after you discover the problem or after coercion ends will usually count as ratification.
Short-Window Grounds: Incapacity, Non-Consummation, Duress
Claims based on mental incapacity or physical inability to consummate the marriage carry some of the shortest deadlines. Depending on the state, you may need to file within 90 days to one year from the date the marriage began or the date you discovered the condition. Courts enforce these tight windows because they assume that someone who continues in a domestic partnership despite knowing about the issue has effectively accepted it.
Duress claims follow a similar pattern. A person forced or threatened into a marriage typically must file within one to two years after the threat is removed. Staying in the household after the coercion ends, even briefly, risks being treated as voluntary acceptance.
Fraud Starts the Clock at Discovery
Fraud gives you more time because the clock does not start until you discover the deception. Most states allow between one and three years from the date you learned of the fraud. Once you uncover the misrepresentation, however, the window begins immediately, and continuing the relationship after discovery weakens your case.
The practical difference is stark. If your spouse was already married when they married you, you are not racing any deadline. If your spouse concealed a criminal history or lied about wanting children, you have a narrow window to act after you find out.
Reopening Marital Property Division
Once a court finalizes the division of marital assets and debts, that allocation is treated as permanent. Reopening it requires showing something went seriously wrong, typically fraud, a material mistake, or newly discovered evidence, and filing within a very narrow window. Most states give you between one and two years from the date of the decree to file a motion to set aside or modify the property division. After that period expires, the original distribution stands even if it was unfair.
The burden of proof is high. You need more than a feeling that you got a bad deal. Courts generally require clear evidence that your spouse actively concealed assets, that a significant piece of property was valued incorrectly due to fraud, or that an important asset was accidentally left out of the proceedings entirely.
Hidden Assets Can Extend the Deadline
When a spouse deliberately conceals property during the divorce, courts treat it seriously. Penalties for hiding assets can include awarding the full value of the concealed property to the other spouse, monetary sanctions, or contempt of court. The discovery of hidden assets can also extend the usual filing deadline, since most states start the clock from the date you discovered (or reasonably should have discovered) the concealment rather than the date of the decree.
Omitted Assets Carry a Longer Window
Omitted assets are different from hidden ones. Sometimes a bank account, investment portfolio, or piece of property is simply forgotten and never addressed in the divorce judgment. Many states allow a separate claim to divide omitted assets, and the timeline tends to be more generous, often three to five years after discovery. If the asset was known to both parties during the divorce and simply ignored, however, courts may refuse to reopen the issue.
QDROs: No Hard Deadline, But Real Risk in Delay
Splitting a retirement account after divorce requires a Qualified Domestic Relations Order, or QDRO, a court order that directs the retirement plan administrator to pay a portion of the participant’s benefits to the other spouse (called the alternate payee). Federal law governs this process, and while there is technically no hard deadline, delay creates serious financial risk.
Under ERISA, a QDRO does not fail simply because it was issued after the divorce, after the participant’s death, or after benefit payments have already started.1U.S. Department of Labor. QDROs – An Overview FAQs The catch is the 18-month segregation rule.
When a plan administrator receives a domestic relations order, the administrator must set aside amounts that would be payable to the alternate payee while the order’s status is being determined. If the order is confirmed as a valid QDRO within 18 months, those segregated funds go to the alternate payee. If the 18 months expire without resolution, the administrator pays those funds to the participant, and any QDRO approved later only applies going forward.2Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form of Benefit A delayed QDRO can cost you months or years of benefit payments you will never recover.
The other risk is simpler. The participant might withdraw or roll over the retirement funds before a QDRO is in place. If the account is drained before the administrator receives your order, there may be nothing left to divide.
Child Support Arrears Never Expire as Modifiable Debt
Child support operates under a different set of rules because of federal law. Under the Bradley Amendment, every child support payment becomes a judgment automatically on the date it comes due. That judgment carries the full legal weight of any other court judgment and is entitled to enforcement across state lines.3Office of the Law Revision Counsel. 42 U.S. Code 666 – Requirement of Statutorily Prescribed Procedures To Improve Effectiveness of Child Support Enforcement
The same federal law prohibits retroactive modification of child support debt. Once a payment is due and unpaid, no state court can erase or reduce it. The only exception applies when a modification petition is already pending, and even then the modification can only apply from the date the other parent was formally notified of the petition.3Office of the Law Revision Counsel. 42 U.S. Code 666 – Requirement of Statutorily Prescribed Procedures To Improve Effectiveness of Child Support Enforcement If you lose your job and stop paying, the unpaid amounts keep stacking up as enforceable judgments until you go to court and get a modification order.
When enforcement crosses state lines, the Uniform Interstate Family Support Act adds another layer. If the paying parent has moved, the statute of limitations for collecting arrears is whichever state’s deadline is longer, the state that issued the original order or the state where the order is registered for enforcement.4Administration for Children & Families. Action Transmittal: Interstate Child Support Policy The system picks the more generous enforcement window for the parent owed support.
Section 1041 and the One-Year, Six-Year Tax Windows
Transferring property between former spouses after a divorce normally triggers capital gains tax, but federal law provides a window where these transfers are tax-free. Under Section 1041 of the Internal Revenue Code, a property transfer to a former spouse is treated as a gift with no taxable gain or loss if the transfer happens within one year after the marriage ends.5Office of the Law Revision Counsel. 26 U.S. Code 1041 – Transfers of Property Between Spouses or Incident to Divorce
Transfers that take longer than one year can still qualify if they are “related to the cessation of the marriage.” Treasury regulations clarify that a transfer made under a divorce decree within six years of the divorce is presumed to meet this standard. After six years, the presumption flips. The IRS assumes the transfer is unrelated to the divorce, and you bear the burden of proving otherwise by showing that legal disputes, business complications, or valuation disagreements prevented an earlier transfer.6GovInfo.

Alimony Recapture Looks Back Three Years
The tax treatment of alimony depends on when your divorce agreement was finalized. For agreements executed after December 31, 2018, alimony payments are neither deductible by the payer nor counted as income for the recipient. The Tax Cuts and Jobs Act eliminated the alimony deduction for all new instruments starting January 1, 2019.7Internal Revenue Service. Divorce or Separation May Have an Effect on Taxes
If your divorce agreement was finalized before 2019, the old rules still apply. The payer deducts alimony and the recipient reports it as income. These older agreements are subject to the recapture rule: if alimony payments decrease by more than $15,000 between the first and second year, or drop significantly over the first three calendar years, the IRS may reclassify part of what was called “alimony” as a property settlement. When recapture is triggered, the payer must add the recaptured amount back to their income in the third year, and the recipient gets a corresponding deduction.8Internal Revenue Service. Publication 504 – Divorced or Separated Individuals
Recapture does not apply when payments decrease because of the death of either spouse, the remarriage of the recipient, or when the payment amount is tied to a fixed percentage of the payer’s business or employment income.8Internal Revenue Service. Publication 504 – Divorced or Separated Individuals If you modified a pre-2019 agreement after 2018 and the modification expressly adopts the new tax rules, the old deduction-and-inclusion treatment no longer applies.9Office of the Law Revision Counsel. 26 U.S. Code 71 – Repealed
When the Clock Pauses
Statutes of limitations do not always run continuously. Most states recognize circumstances that pause or “toll” the deadline. The specifics vary by jurisdiction, but several categories appear in nearly every state.
- Minority. If the person entitled to bring the claim is under 18, the clock typically does not start until they reach the age of majority.
- Mental incapacity. A person who lacks the mental capacity to pursue legal action may have the deadline paused for the duration of the incapacity, though most states cap this extension.
- Absence from the state. When the person you need to sue leaves the state, many jurisdictions stop the clock for the period they are absent.
- Fraud concealment. If the other party actively hid the facts giving rise to your claim, the deadline often does not begin until you discovered or reasonably should have discovered the fraud.
Fraud concealment is particularly relevant in property division disputes. A spouse who buries assets in shell companies or unreported accounts cannot benefit from a filing deadline that the other spouse missed because of the concealment itself. You are expected to exercise reasonable diligence, though. Courts will not toll the deadline indefinitely if the hidden assets could have been found through ordinary financial investigation during the divorce.
One Deadline Your Decree Does Not Reset: Joint Debts
A divorce decree can assign each joint debt to one spouse, but creditors are not bound by that arrangement. If your name is on a loan or credit account, the lender can still come after you for the full balance even if the decree says your ex-spouse is responsible for the payment. Sending a copy of the decree to the lender does not end your responsibility, and the creditor’s statute of limitations on the underlying debt runs independently of your divorce timeline. The only way to sever your connection to a joint debt is for your former spouse to refinance in their name alone, or for the creditor to release you contractually.10Consumer Financial Protection Bureau. Can a Debt Collector Contact Me About a Debt After a Divorce? If a creditor sues you for an ex-spouse’s assigned debt, your recourse is to enforce the divorce decree against them in a separate action.
