Can an Ex-Spouse Make Claims on an Estate?

The General Rule: Divorce Cuts Off Inheritance

Once a divorce is finalized, you generally lose the automatic inheritance rights that come with marriage. You can't claim an elective share, spousal allowance, or intestate share as a surviving spouse. Most states have revocation-on-divorce statutes that automatically revoke certain will provisions and beneficiary designations naming a former spouse, subject to state law and the type of asset.

But that's only the starting point. Several categories of claims survive divorce — and some are strengthened by it.

Claims That Survive Divorce

Divorce decree obligations. If the divorce decree ordered your ex-spouse to do something — maintain life insurance, transfer property, pay a lump sum — and they didn't do it before they died, you may have an estate claim to enforce that obligation. The basis and procedure depend on the decree and state law; their death does not automatically resolve an unperformed obligation.

Child support arrears and future obligations. Unpaid child support is a vested debt. Most states allow you to accelerate future support through the child's age of majority and file the total as a priority creditor claim. Child support claims typically rank above general unsecured creditors.

QDRO-secured retirement assets. If a Qualified Domestic Relations Order was filed and qualified by the plan administrator before death, the plan recognizes your assigned interest. Whether payments continue after death depends on the plan and any survivor protections in the order. If the QDRO was never finalized, you may be able to pursue a posthumous QDRO, but the result depends on the plan and facts and can be harder after assets are distributed.

Joint debts. This isn't a claim on the estate — it's a liability. Co-signed debts (mortgages, credit cards, auto loans) remain your obligation regardless of what the divorce decree says about who was supposed to pay them. But you may be able to file a contribution or indemnification claim against the estate to recover payments you make on debts that were assigned to the deceased.

Property the decree awarded you but wasn't transferred. If the divorce decree awarded you the house, a vehicle, or other titled property and the transfer was never completed, you can petition the probate court (or the family court, depending on jurisdiction) to enforce the transfer.

Claims Most People Miss

Constructive trust claims. If your ex-spouse converted marital assets into a form that the divorce decree didn't specifically address — like using marital funds to buy property titled solely in their name after the divorce was filed — you may be able to impose a constructive trust on those assets in probate.

Fraudulent transfer claims. If your ex-spouse transferred assets to family members or a new spouse specifically to prevent you from collecting what the decree awarded you, those transfers can potentially be clawed back during probate.

Life insurance proceeds. If the divorce decree required them to maintain a life insurance policy naming you or the children as beneficiary and they let it lapse or changed the beneficiary, you have a breach claim. On ERISA-governed employer policies, the claim is even more direct — whoever is named on the beneficiary form gets paid, regardless of state revocation laws.

The ERISA Exception

Federal law creates one major exception to the general rule that divorce severs benefit rights. Under ERISA (the Employee Retirement Income Security Act), employer-sponsored benefit plans — 401(k)s, pensions, group life insurance — must follow the written beneficiary designation on file. State revocation-on-divorce statutes don't apply.

If your ex-spouse never updated their employer 401(k) or group life beneficiary form after the divorce, the plan administrator generally follows the designation on file under ERISA, even if the deceased intended otherwise. Another claimant may challenge the payout, and the outcome depends on the plan documents and facts.

Time Limits

Probate creditor claims have deadlines that vary by state and can be short. Confirm the applicable deadline with the probate court or an attorney promptly; missing it may bar an otherwise valid claim.

If you don't know whether probate has been opened, check with the probate court in the county where your ex-spouse lived. If it hasn't been opened, ask the court or an attorney whether you can petition to open it.

What to Do

1. Pull out your divorce decree and read every obligation it imposed on your ex-spouse. Each unfulfilled obligation is a potential estate claim.
2. Check whether a QDRO was finalized with every retirement plan mentioned in the decree.
3. Contact your children's Social Security case — apply for survivor benefits immediately.
4. File creditor claims in the probate proceeding for child support arrears, unperformed decree obligations, and indemnification on joint debts.
5. Consult a family law or probate attorney if the estate is contested or the amounts are significant.
