Michigan automatically revokes most beneficiary designations naming your former spouse the moment your divorce is finalized, under MCL 700.2807. However, this automatic revocation does not apply to ERISA-governed 401(k) and pension plans, which require you to manually file a new beneficiary form after the judgment is entered.
Changing beneficiaries during a Michigan divorce is one of the most overlooked steps in the entire process, and the consequences of getting it wrong are permanent. Michigan's revocation-on-divorce statute provides a safety net for life insurance, IRAs, and payable-on-death accounts, but federal law creates a major gap for employer retirement plans. This guide explains exactly which accounts revoke automatically, which require manual action, and how to protect the people you intend to inherit your assets after a divorce in Michigan.

What Is Automatic Beneficiary Revocation in Michigan?
Automatic beneficiary revocation in Michigan means your divorce judgment legally cancels any provision naming your former spouse as a beneficiary in most governing instruments, under Mich. Comp. Laws § 700.2807. The statute treats your ex-spouse as if they had disclaimed the interest or died immediately before the divorce, redirecting assets to your contingent beneficiary or estate.
Michigan enacted this revocation-on-divorce statute as part of the Estates and Protected Individuals Code (EPIC), originally effective April 1, 2000, and amended by 2016 Public Act 57. The law presumes that divorcing couples intend to sever their financial relationship completely, even if they forget to update paperwork. The statute reaches any "governing instrument" defined under Mich. Comp. Laws § 700.1104, which expressly includes deeds, wills, trusts, life insurance and annuity policies, payable-on-death (POD) accounts, transfer-on-death (TOD) securities, and similar dispositive instruments. This broad definition is why most beneficiary changes happen by operation of law in Michigan.
Which Beneficiary Designations Revoke Automatically?
Michigan automatically revokes ex-spouse beneficiary designations on life insurance policies, IRAs, POD bank accounts, TOD investment accounts, wills, trusts, and joint tenancy survivorship rights upon divorce, under Mich. Comp. Laws § 700.2807. The statute also severs joint tenancy with right of survivorship between former spouses, converting the ownership into a tenancy in common.
The revocation applies only to instruments the account holder could change alone. The statute defines a "revocable" designation as one where the divorced individual was alone empowered, at the time of the divorce, to cancel the designation favoring the former spouse. Here is how the major asset categories break down for a Michigan divorce:
- Life insurance beneficiary divorce: A standard, individually-owned life insurance policy beneficiary designation naming your ex-spouse is automatically revoked.
- IRA beneficiary divorce: Traditional and Roth IRA beneficiary designations are generally revoked, though the IRA custodian's home-state law may sometimes control.
- Bank account beneficiary divorce: POD designations on checking and savings accounts revoke automatically.
- TOD investment accounts: Securities registered in transfer-on-death beneficiary form revoke automatically.
- Wills and revocable trusts: Bequests and fiduciary nominations to a former spouse are revoked.
Importantly, this statute does not disinherit children you share with your former spouse. The revocation of "relatives of the former spouse" applies only to people related to your ex but not to you.
The Critical ERISA Exception for 401(k) Plans
Michigan's automatic revocation does NOT apply to ERISA-governed retirement plans, including most 401(k), 403(b), and employer pension plans, because federal law preempts state revocation statutes. The U.S. Supreme Court confirmed this in Egelhoff v. Egelhoff, 532 U.S. 141 (2001), holding that ERISA's preemption provision under 29 U.S.C. § 1144(a) supersedes any state law that relates to an employee benefit plan.
This is the single most dangerous gap in Michigan divorce planning. In the Egelhoff case, a husband named his wife as beneficiary of his $46,000 Boeing life insurance policy and pension. The couple divorced, he died two months later without updating his forms, and his ex-wife collected the proceeds despite a state automatic-revocation statute identical in purpose to Michigan's. The Supreme Court ruled the plan administrator had to follow the plan documents, not the state law. The practical lesson for a 401(k) beneficiary divorce in Michigan is unavoidable: you must affirmatively file a new beneficiary designation form with your plan administrator after the divorce judgment is entered. If you do not, your former spouse will legally receive your 401(k) balance even though Michigan law tried to revoke them.
Difference Between Marital Property Division and Beneficiary Changes
Dividing retirement accounts in your divorce judgment is a separate legal step from updating death beneficiaries, and completing one does not accomplish the other. A divorce decree or Qualified Domestic Relations Order (QDRO) splits the account value between living spouses, while a beneficiary designation controls who inherits the account when you die.
Many people wrongly assume that once their divorce is final and property is divided, their estate plan is automatically fixed. In Michigan, the divorce judgment under Mich. Comp. Laws § 552.101 governs property rights between the parties and can require a spouse to maintain or waive life insurance. A QDRO is the federal mechanism that lawfully assigns a portion of an ERISA plan to a former spouse during divorce, and ERISA expressly exempts properly executed QDROs from its anti-alienation rules. However, neither the judgment nor the QDRO updates your death beneficiary forms for the assets you keep. After your divorce concludes, you should treat beneficiary updates as a distinct checklist item covering every retirement account, insurance policy, and bank account you retain.
How to Change Beneficiaries After a Michigan Divorce
To change beneficiaries after a Michigan divorce, contact each financial institution, request its beneficiary designation form, complete it with your new chosen beneficiaries, and submit it for the institution's records. This process should be completed within 30 days of your judgment for every ERISA plan, since those do not revoke automatically.
Follow this step-by-step checklist after your divorce is finalized in Michigan:
- Locate your divorce judgment and confirm any obligations, such as a requirement to keep your children as life insurance beneficiaries.
- Contact your 401(k), 403(b), and pension plan administrators and submit new beneficiary forms immediately, since ERISA plans do not revoke automatically.
- Update IRA beneficiary designations directly with each custodian to avoid disputes over which state's law applies.
- File new beneficiary forms with your life insurance company, even though Michigan revokes the old one automatically, to confirm your intended beneficiary.
- Update POD designations on bank accounts and TOD designations on brokerage accounts.
- Revise your will and any revocable trust through a Michigan estate planning attorney.
- Update your funeral representative designation and power of attorney documents, which also revoke an ex-spouse automatically under EPIC.
Keep dated copies and confirmations of every change. Documentation prevents your intended beneficiaries from litigating the issue after your death.
What Happens If You Die Before Updating Beneficiaries?
If you die before manually updating an ERISA-governed 401(k) or pension beneficiary in Michigan, your former spouse will legally receive those funds despite the divorce, because federal law requires the plan to pay the named beneficiary. For non-ERISA assets like life insurance and IRAs, Mich. Comp. Laws § 700.2807 automatically redirects the funds to your contingent beneficiary or estate.
The outcome depends entirely on the type of account. For a standard life insurance policy, the proceeds pass to your named contingent beneficiary, or if none exists, to your estate, where they are distributed under your will or Michigan intestacy law. For an employer 401(k), the absence of a new form is fatal to your intentions; the plan administrator owes a duty to the named beneficiary on file. Michigan courts apply the revocation statute strictly. In a 2021 Michigan Court of Appeals decision involving the Grablick Trust, the court held that even the biological daughter of a former spouse lost her trust inheritance because the disposition was revoked by the divorce. The express-terms exception means a properly drafted instrument can preserve a designation if it states the gift survives divorce, but absent that language, automatic revocation controls non-ERISA assets.
Special Situations: Irrevocable Trusts and IRA Custodians
Michigan's automatic revocation does not apply to irrevocable life insurance trusts (ILITs) or to IRAs whose custodial agreements specify another state's governing law. An ILIT naming a former spouse remains binding because the divorced individual could not unilaterally cancel that designation, which removes it from the statute's reach under Mich. Comp. Laws § 700.2807.
Two categories of accounts require extra attention during a Michigan divorce. First, irrevocable trusts are designed to be unchangeable, so if you established an ILIT naming your spouse before the marriage broke down, the divorce will not remove them. You will need to address this through the divorce settlement or separate legal action. Second, IRA beneficiary disputes can turn on conflict-of-laws questions. While Michigan's statute covers IRAs as governing instruments, an IRA custodian headquartered in another state may include fine print in its custodial agreement declaring that its home state's law governs beneficiary designations. That clause could override Michigan's automatic revocation. To eliminate any ambiguity, file a fresh IRA beneficiary form directly with each custodian after your divorce rather than relying on the statute. The constitutionality of these revocation statutes was confirmed by the U.S. Supreme Court in Sveen v. Melin (2018), addressing a nearly identical Minnesota law.
