Estate Planning After Divorce: 7 Documents You Need to Update Immediately

Why Estate Planning After Divorce Cannot Wait

The judge signed the decree. The lawyer's invoice cleared. You moved out, or they did. And on paper, your ex-spouse is still the named beneficiary on your 401(k), your IRA, your life insurance, and probably your healthcare proxy. The divorce decree did not touch any of those. It cannot. A separate set of forms, on a separate set of platforms, controls every one of them, and until you actively log in and change them, your ex inherits the assets, makes your medical decisions, and signs your financial paperwork.

This is the part of the divorce that nobody schedules a meeting about. Estate planning after divorce is not a nice-to-have. Forty-eight states have some version of a "revocation by divorce" statute that automatically strips an ex-spouse out of a will, but the rules vary wildly, almost none of them touch retirement accounts, and the few that try get preempted by federal law. The only way to be sure your wishes match your new life is to update the documents yourself. Here are the seven that need it, in roughly the order you should hit them.

Document One: The Will Itself

Most states have a revocation-by-divorce statute that automatically treats your ex as if they predeceased you, for purposes of your will. That sounds like protection. In practice it is full of holes. The statute may not apply if you remarry the same person. It may not apply to a separation that never finalized. It may not apply if the will was executed in a different state under different rules. And in every case, it leaves your old will partially gutted, with no clear successor named for the parts your ex was supposed to handle.

Rewrite the will. Name a new executor. Reset the beneficiaries cleanly. Update the guardianship clause for any minor children, because the natural-guardian default after divorce can get messy if you and the ex disagree. If you had a pour-over will into a joint trust, that whole structure needs to be redone too. Our walk-through of how to write a will covers the rebuild from scratch, which is almost always faster than trying to amend the old one.

Document Two: Financial Power of Attorney

If your ex-spouse has financial POA over you and you do not revoke it, they can keep moving money in your name long after the marriage ends. Most divorces never address this. The POA was signed years ago, filed away, and forgotten. Until they need it, or worse, until they decide to use it.

Revoke the old POA in writing. Send formal notice to every financial institution where your ex might have used it. Record the revocation with your county recorder if the original POA was ever recorded (common for real estate transactions). Then sign a new durable financial POA naming a successor you actually trust now. A sibling, a parent, an adult child, a longtime friend, anyone but the person you just divorced. For more on the difference between immediate and conditional POA structures, see our piece on power of attorney explained.

Document Three: Healthcare Proxy

The healthcare proxy is the document that says who tells the doctor whether to keep you on the ventilator. If your ex is still listed, that is the person the hospital calls. Some states will treat the divorce as automatic revocation. Many will not, especially if the proxy was signed in another state. The path of least resistance for a hospital is to honor the document on file. Do not make them guess.

Revoke the old proxy. Sign a new one. Name a primary and a backup. Make sure both have a copy. Upload to your patient portal at the major hospital systems near you so the document shows up automatically on intake.

Document Four: Life Insurance Beneficiary

Life insurance beneficiary updates are usually the easiest and the highest-stakes change you can make. Log into the policy. Update the primary. Update the contingent. Save the confirmation.

One critical wrinkle: if the divorce decree includes a court order requiring you to maintain life insurance for the benefit of your ex (often as part of alimony or child support), you cannot just remove them. Read the decree carefully and follow what it actually requires. The smart structure is usually a separate, court-ordered policy with the ex as beneficiary (capped at the obligation amount), and your main policy with the new beneficiaries you actually want.

Document Five: IRA Beneficiary

IRAs are governed by the IRA custodian, not by ERISA, but in practice the rule is identical: the beneficiary form on file controls. Whatever the will says, whatever the divorce decree says, the custodian pays the form. Update primary and contingent on every traditional IRA, Roth IRA, rollover IRA, SEP, and SIMPLE you own. If you have multiple IRAs at multiple custodians (common after job changes), do them all. One stale form on an old rollover IRA can wipe out the whole intent of an otherwise clean update.

While you are in there, look at the post-SECURE Act distribution rules. If your new primary beneficiary is your minor child, the inherited IRA rules are now stricter than they were when you set up the account. A see-through trust as beneficiary may make more sense than the child directly, especially if you do not want a 21-year-old inheriting a seven-figure account outright.

Document Six: HSA, 529, and the Other Accounts Nobody Remembers

The list of accounts with their own beneficiary form is longer than people expect. HSAs (health savings accounts) have a beneficiary designation that is rarely updated and is taxed harshly if it goes to a non-spouse. 529 college savings plans have an account owner and a successor owner; if your ex is the successor owner, they take control of the account if you die, which means they decide which kid gets the money and how it is spent. UTMA and UGMA custodial accounts have a custodian; replace them too.

• HSA: log in, change beneficiary, prefer spouse or estate over a non-spouse individual to avoid full taxation in year of death.
• 529: change the successor account owner to someone other than the ex, even if the kids are the named beneficiaries.
• Brokerage TOD: any transfer-on-death registration on a taxable brokerage account needs an update.
• Bank POD: payable-on-death designations on checking and savings sit on the bank's form, not yours.
• Series I bonds and Treasury Direct: separate beneficiary form on TreasuryDirect.gov.

Document Seven: Trust Beneficiaries and Trustees

If you and your ex set up a joint revocable trust, it is now a structural problem. A joint trust assumes one shared estate. After divorce, you have two. Most attorneys will recommend revoking the joint trust and creating two new separate trusts, each retitled to hold the assets each spouse received in the divorce settlement.

The trustee question is just as important. If your ex was named as your trustee or successor trustee, replace them. If your ex was named as trustee for a trust benefiting your kids, you may want to swap them out for a neutral co-trustee or a corporate trustee, especially if the relationship is contentious. The healthcare side has its own structural choices too; if you are unsure about how the medical document hierarchy interacts with the financial side, our breakdown of healthcare proxy vs living will clarifies what each document actually does in a hospital setting.

The QDRO and What It Does Not Do

A Qualified Domestic Relations Order is the court order that lets a 401(k) or pension be split between divorcing spouses without triggering early-withdrawal penalties or losing the tax-deferred treatment. A QDRO is necessary if the divorce settlement includes any portion of an employer retirement plan going to the other spouse. It must be drafted carefully, approved by the plan administrator, and signed by the judge. IRAs do not need a QDRO; they use a "transfer incident to divorce" instead.

What a QDRO does not do is update your beneficiary designation. It moves the agreed-upon portion of the account to the ex-spouse. Whatever stays in your account still goes to whoever is on the beneficiary form. Many people sign the QDRO, watch the agreed split happen, and never realize the rest of the account still names their ex as the contingent beneficiary.

Why "I'll Do It Later" Becomes a Ten-Figure Mistake

The case law on this is brutal. People die in the gap. The 401(k) goes to the ex. The life insurance goes to the ex. The healthcare decisions go to the ex. The kids inherit nothing because the named beneficiary form was never updated. The new spouse inherits nothing for the same reason. Family fights for years and loses, because federal law and state probate code both side with the document on file, not the obvious intent.

None of this is hard. None of it requires a lawyer for the beneficiary updates themselves; you can do every one of them in a single afternoon at your kitchen table. The will, the POA, the healthcare proxy, and the trust restructure are the parts that benefit from a professional, but even those move quickly when you have the rest of the information already organized.

Pulling It Together

Estate planning after divorce is a one-weekend project that protects everything you just spent a year fighting for. Seven documents. One Saturday for the beneficiary forms. One sit-down with an attorney for the will, POA, healthcare proxy, and any trust restructuring. The decree is the legal end of the marriage. The beneficiary updates are the operational end.

This is also the moment to think about who can read the new plan. Most estate platforms store your will, your asset list, your beneficiary detail, and your family notes in plaintext on their servers, where a single breach exposes the whole picture to anyone who wants it, including, sometimes, the ex. DocSats was built for the version of estate planning where that does not happen: every document is encrypted in your browser before it is ever stored, so even DocSats cannot read your beneficiary list or your reasoning. The plan is anchored to the Bitcoin blockchain for tamper-evident proof of existence, and the digital assets clauses cover the crypto, the brokerage, and the modern accounts that did not exist when the original divorce playbook was written. The decree is final. The next step is an estate plan that finally matches your new life, privately.
