Estate Planning After Divorce: Updating Your Will, Trust, and Powers of Attorney

Most people assume divorce automatically cancels their ex from their estate. For most documents, that assumption is wrong — and for ERISA retirement accounts and employer life insurance, it is dead wrong. Failing to update your estate plan after divorce is one of the most common and most irreversible financial mistakes.

Why divorce doesn't automatically fix your estate plan

Most states have adopted Uniform Probate Code § 2-804 or a similar statute that automatically revokes will provisions and certain non-probate transfers in favor of an ex-spouse upon divorce.² For a traditional will, a state-law revocation statute may protect you. For many other documents, it will not.

The table below summarizes what state law typically does — and doesn't — fix automatically:

The safest rule: do not rely on state revocation statutes for anything. File new documents for every category. "Probably protected by state law" is not a standard you want to bet your estate on.

1. Execute a new will

Even in states with strong automatic revocation statutes, your existing will was written around a marriage that no longer exists. Executors, beneficiaries, and guardians all likely need updating.

Executor. If your ex-spouse was named executor, they retain that appointment in states that don't automatically revoke it. Even where state law removes them, the fallback executor named in the will (often "my spouse, or if predeceasing, my sibling") may not be who you'd choose now. Name a new executor who reflects your current circumstances.

Beneficiaries. A will that leaves your estate "to my spouse, or if predeceasing, to my children equally" now passes to your children — which may be your intent. But if you've remarried, entered a new relationship, or wish to make charitable provisions, a new will is the only clean mechanism.

Minor children. If you and your ex share minor children, consider a testamentary trust within your will. Assets passing directly to a minor require court-supervised guardianship of property; assets passing to a trustee for the child's benefit do not. A well-drafted testamentary trust lets you specify the age at which children receive principal and keep assets managed by someone you choose — not under court administration until age 18.

2. Amend or restate your revocable living trust

A revocable living trust does not automatically update when your marital status changes. Every role your ex-spouse held in the trust needs to be replaced.

Successor trustee. If your ex-spouse is named to take over as trustee upon your incapacity or death, they retain that role until you formally amend the trust. An ex serving as trustee of a trust holding all your post-divorce assets — managing investments, making distributions to your children, handling real estate — is an obvious problem.

Beneficiary. Your ex-spouse as a trust beneficiary is not automatically removed in most states. A formal amendment is required.

How to amend. Most revocable trusts allow amendment by a signed written instrument. A complete trust restatement (which replaces the entire trust document while preserving the trust entity and its tax identification number) is often cleaner than layering multiple amendments, especially after a divorce where several provisions need updating simultaneously.

High-asset note. With the federal estate/gift exemption permanently set at $15M per person under the One Big Beautiful Bill Act (2025), the AB trust structure (bypass trust / credit shelter trust) that many married couples built into their revocable trusts to shield assets from estate tax is now unnecessary for most estates under $30M combined.³ Post-divorce trust restructuring is an opportunity to simplify your estate plan and eliminate complexity that no longer serves a tax purpose.

3. Revoke and replace your powers of attorney

Durable financial power of attorney

A durable financial POA authorizes your agent to conduct virtually any financial transaction on your behalf — sign contracts, manage investment accounts, sell real estate, access bank accounts — if you become incapacitated. If your ex-spouse holds this document, they can legally act on your finances during any period of incapacity, including a serious illness that occurs before the divorce is final.

Immediate revocation. If your ex is your current financial POA agent, revoke it in writing now — do not wait for the divorce decree. The revocation should be signed and notarized, and copies should be delivered to every institution (bank, brokerage, real estate closing agent) that has your current POA on file. Verbal revocation is typically not sufficient.

Some states do automatically revoke. California Probate Code § 4154, for example, automatically terminates a POA that designates a spouse on dissolution or annulment of the marriage. But relying on state law is risky — confirm with your attorney whether your state applies automatic revocation and whether that revocation is self-executing or requires additional notice to institutions holding the document.

Healthcare power of attorney / healthcare proxy

Your healthcare proxy authorizes someone to make medical decisions for you when you cannot. This is distinct from your advance directive (living will), which records your instructions. Your healthcare proxy is the person who communicates and advocates for those instructions with your medical team.

If your ex-spouse is named as your healthcare proxy, they can consent to or refuse treatment, authorize surgery, and make end-of-life decisions on your behalf during any period of incapacity. Execute a new healthcare proxy immediately — naming someone you currently trust — and deliver copies to your doctors and any hospital where you receive regular care.

4. Update your advance directive (living will)

An advance directive records your preferences for end-of-life medical treatment: resuscitation, mechanical ventilation, artificial nutrition, palliative care. Unlike a POA, an advance directive speaks for itself rather than naming an agent to decide.

If your current directive was drafted around your marriage — for example, authorizing your ex-spouse as the person to convey your wishes to providers, or naming them as the individual whose signature your healthcare team should seek — update it. Even if the directive doesn't explicitly name your ex, a stale document raises practical complications in a medical emergency if the document's context implies a marital relationship that no longer exists.

5. Update HIPAA authorizations and emergency contacts

HIPAA restricts who can receive your protected health information. If your ex-spouse is listed on any HIPAA authorization at your doctors' offices, hospital system, or pharmacy, revoke those authorizations and update with current contacts.

Also update emergency contact information at your employer, your children's school, and any medical provider. These records don't carry legal weight, but a hospital that has your ex-spouse as the listed emergency contact will attempt to notify them first — which may not be your preference.

6. Guardianship designations for minor children

If you and your ex share minor children, your ex is the surviving parent by law and typically assumes full custody if you predecease them — regardless of what your will says. Courts make guardianship decisions based on the child's best interest; a testamentary guardian nomination is persuasive but not binding.

However, if your ex-spouse were to predecease you, or if you are both incapacitated simultaneously, the guardian you've named in your will controls. Designate both a primary and backup guardian who reflect your current life. If your children have step-siblings, half-siblings, or other family relationships that emerged from the divorce, consider whether your guardian choice keeps those relationships intact for the children.

7. Beneficiary designations — the ERISA trap in detail

This is covered in depth in our Post-Divorce Financial Checklist and Life Insurance in Divorce guide. The short version:

• ERISA employer plans (401k, 403b, pension, employer group life insurance): State revocation-on-divorce statutes do not apply. The plan document and the beneficiary designation on file control. File a new beneficiary form with your plan administrator immediately — before you do anything else.
• IRAs: IRAs are not ERISA plans and in most states with UPC § 2-804 adoption, an ex-spouse beneficiary designation is revoked automatically on divorce. But do not rely on this. File a new IRA beneficiary designation with your custodian.
• Individual life insurance: State revocation statutes often apply, but policy terms and state law vary. Contact the insurer and submit a new beneficiary form.
• Annuities, TOD brokerage accounts, bank accounts with POD designations: Same approach — file new forms. Don't assume the state revocation statute swept these automatically.

Timing — during the divorce vs. after

During the divorce: Most states issue automatic temporary restraining orders (ATROs) upon filing that prohibit either party from changing beneficiaries or dissipating marital assets. However, ATROs typically allow changes to healthcare proxies and advance directives (medical decisions for yourself), and often permit updating a will to remove your spouse as executor and name a replacement. They typically do NOT permit changing financial beneficiaries on retirement accounts or life insurance during the pendency.

Critically, if your spouse holds your financial POA: revoke it immediately, even during the divorce. The risks of your spouse controlling your finances if you're incapacitated during active litigation outweigh any ATRO concern — your attorney can guide you on the mechanics in your jurisdiction.

After the decree: Complete your full estate plan update within 30 days. Prioritize: (1) ERISA beneficiary designations, (2) financial and healthcare POA, (3) will and trust restatement, (4) all remaining beneficiary forms. The longer these remain stale, the longer you carry the risk of an outcome you did not intend.

How a CDFA coordinates with your estate attorney

Estate attorneys draft the documents. A CDFA-credentialed fee-only financial advisor ensures the financial side of the estate plan is coherent with the settlement — and models the tax consequences of the choices.

Specific coordination points:

• Asset titling. Property you receive in the settlement must be retitled to match the estate plan. A home titled solely in your name that your trust was supposed to hold is a probate risk. A CDFA tracks the asset transfer deadlines and works with the estate attorney to ensure titling and ownership records align.
• Trust structure after settlement. If the settlement gives you a large pre-tax retirement account, a taxable brokerage account, and the marital home, the estate planning strategy for each is different. A CDFA models the after-tax distribution sequence and helps structure where assets sit (in the trust, outside the trust, in a named account) for tax efficiency.
• Post-divorce tax re-planning. The filing status change from MFJ to single (or Head of Household) affects both your current-year tax and your estate planning horizon. A CDFA models the new bracket structure and identifies Roth conversion windows, loss-harvesting opportunities, and income timing strategies that a will alone can't address.

2. Uniform Probate Code § 2-804 — Uniform Law Commission. Automatic revocation of revocable dispositions (will provisions, POA designations, beneficiary designations, jointly-held property interests) in favor of a former spouse upon divorce, for assets not governed by ERISA. Adopted by a majority of U.S. states in substantially similar form.
3. IRS — Estate and Gift Taxes. The One Big Beautiful Bill Act (July 2025) permanently set the federal estate, gift, and generation-skipping transfer tax exemption at $15 million per person ($30 million per married couple), indexed for inflation thereafter. 2026 exemption: $15 million per person.
4. ERISA § 514 — Preemption (29 U.S.C. § 1144) (LII / Cornell Law). Broadly preempts state laws that "relate to" employee benefit plans covered by ERISA. As applied in Egelhoff: state revocation-on-divorce statutes are preempted as applied to ERISA plan beneficiary designations.
5. Kennedy v. Plan Administrator for DuPont Savings & Investment Plan, 555 U.S. 285 (2009) — Justia. Confirmed that ERISA plan administrators must follow plan documents and the beneficiary designation on file — not a waiver executed in a divorce decree. A spouse's waiver in the decree is enforceable between spouses, but the plan administrator is not bound by it.
