Some documents fix themselves the day your divorce is final. Others, including the ones that control your retirement account, never change unless you change them yourself.
Updating your estate plan after divorce in Wisconsin is not a one-step fix, because Wisconsin law doesn’t treat every document the same way. Some provisions favoring your former spouse disappear automatically the moment your divorce becomes final. Others, including the beneficiary on your 401(k) and the agent on your financial power of attorney, follow completely different timelines, and a few won’t change at all unless you personally file new paperwork. Treating “I’m divorced now” as the end of the estate planning conversation is one of the most common and most expensive assumptions a newly divorced person makes. This guide walks through exactly what Wisconsin law changes on its own, what it leaves untouched, and the order in which to fix what’s left.
Wisconsin has a statute built specifically for this moment. Wis. Stat. § 854.15 provides that once a divorce, annulment, or similar event is final, any revocable gift to a former spouse (or to that former spouse’s relatives) inside a “governing instrument” executed before the divorce is automatically revoked. The same statute revokes any nomination of the former spouse to serve in a fiduciary role, such as personal representative, trustee, or agent, inside that instrument. The law treats the revoked gift as if the former spouse had disclaimed it, and treats a revoked fiduciary nomination as if the former spouse had died the moment before the divorce became final.
That sounds like it solves the problem. In practice, it solves a narrower slice of the problem than most people expect. Section 854.15 only reaches documents you already signed; it rewrites nothing and names no one new. If your ex-spouse was your named personal representative and sole beneficiary, the statute removes them, but it does not appoint a replacement executor or decide who inherits instead. Without a new will, Wisconsin’s intestate succession statute, Wis. Stat. § 852.01, steps in to decide who gets what, in a fixed order that has nothing to do with your actual wishes post-divorce.
The statute also only applies once the divorce is final, not once it’s filed. If something happens to you while the case is still pending, a will executed during the marriage may still be read as if your soon-to-be-former spouse were entitled to everything in it, since Section 854.15 hasn’t been triggered yet.
A will is usually the first document people think to update, and the last one that fully solves the problem. Even after Section 854.15 strips your former spouse out of the will's gifts and fiduciary nominations, the document still needs to be rewritten for three reasons the statute can't handle. First, it still needs a living, intentional distribution plan rather than whatever is left once the revoked clauses drop out. Second, if you have minor children, the will is the only document that can nominate a guardian, and a divorce doesn't change who you'd want raising your kids if something happened to you; it just means you should name that person affirmatively rather than relying on an outdated nomination. Third, if your former spouse was the backup guardian or alternate executor behind a parent or sibling, those layered nominations usually need a fresh look too.
A revocable living trust is the document people most often assume is covered by the same automatic fix, and it's the one most likely to be wrong on paper for years. Trusts are governed in Wisconsin by the Wisconsin Trust Code, Wis. Stat. ch. 701, and while courts have extended revocation-on-divorce principles to some trust provisions, a trust is a management structure with assets already titled into it, not a simple gift. If your former spouse was named successor trustee, that role needs to be formally replaced in an amendment or restatement, not just assumed vacant. If the trust was drafted while you were married to preserve Wisconsin marital property characterization for the double step-up in basis, that language is now describing a tax status that no longer exists for you, since divorce ends marital property treatment of your assets going forward. Our trusts page covers how a Wisconsin trust is structured and funded; after a divorce, that structure usually needs rebuilding, not patching.
Nothing in a post-divorce estate plan moves faster, or on a more easily missed schedule, than your powers of attorney. Wisconsin runs the financial and health care versions on two entirely different timers, and confusing them leaves a real gap.
Your financial power of attorney changes the moment the divorce case starts, not when it ends. Under Wis. Stat. § 244.10(2)(c), an agent’s authority terminates automatically when an action for divorce, annulment, or legal separation is filed, if that agent is your spouse. That is a sharp, immediate cutoff, which is good news if you wanted your spouse out of your finances right away, but it also means you have no named financial agent at all from the day you file until you sign a new one. Waiting until the divorce is final to replace that document leaves months where no one has clear authority to manage your accounts or property if you become incapacitated.
Your health care power of attorney runs on the opposite schedule. Wis. Stat. § 155.40(2) provides that a health care power of attorney naming your spouse as agent is revoked only once the annulment or divorce is actually obtained, not when the case is filed. That means a soon-to-be-former spouse named as your health care agent still has full authority to make medical decisions for you throughout the entire pendency of the divorce, however long that takes. If you’d rather not have that person making end-of-life decisions while the divorce is still playing out, you need to sign a new health care power of attorney immediately; filing for divorce does nothing on its own. Our Wisconsin power of attorney requirements guide and our health care power of attorney guide both cover the signing formalities each document requires.
The most expensive gap in post-divorce planning has nothing to do with Wisconsin law at all. It’s federal preemption. Employer-sponsored retirement plans, including 401(k)s, pensions, and most group life insurance policies, are governed by the federal Employee Retirement Income Security Act, known as ERISA. The U.S. Supreme Court held in Egelhoff v. Egelhoff that ERISA preempts state revocation-on-divorce statutes like Wis. Stat. § 854.15 entirely for plans it covers. In plain terms: if your former spouse is still named as the beneficiary on your 401(k) when you die, they inherit it, in full, no matter what your divorce decree says and no matter how long ago the divorce was finalized. Wisconsin's automatic fix simply does not reach that account.
IRAs sit in a slightly different category since they aren’t ERISA plans, but the practical advice is identical: the plan administrator or custodian pays out according to whatever beneficiary form is on file, not according to your will, your trust, or your divorce judgment. The same is true for individual (non-group) life insurance policies and for payable-on-death or transfer-on-death designations on bank and brokerage accounts, which generally do fall under Wisconsin’s broader governing-instrument revocation rules but are still worth confirming directly with the institution rather than assuming the paperwork caught up automatically.
The fix here has nothing to do with legal drafting. It’s a phone call or an online form submitted directly to each plan administrator, insurer, and bank, changing the named beneficiary by hand. No attorney, no court, and no statute does this step for you.
Real estate titled jointly during the marriage is its own trap, because joint tenancy's right of survivorship isn't the kind of gift Section 854.15 reaches. If you and your former spouse still own the house as joint tenants when one of you dies, the surviving joint tenant takes the whole property automatically, by operation of the deed itself, regardless of what either person's will says or what the divorce judgment intended. Most Wisconsin divorce judgments resolve this directly, requiring one spouse to quitclaim their interest to the other or ordering the house sold and the proceeds divided, and that deed transfer needs to actually get recorded, not just referenced in the judgment. A transfer-on-death deed naming a former spouse works the same way: Wisconsin treats it as a governing instrument under Section 854.15, so a TOD deed signed during the marriage is generally revoked once the divorce is final, but confirming that with a fresh deed naming your actual intended beneficiary is far safer than relying on a statute to have sorted out a public land record correctly.
Section 854.15 isn’t absolute, and the exception matters most for separating parents. The statute does not apply where the express terms of a governing instrument, a court order, or a contract relating to the division of property between you and your former spouse say otherwise. Divorce judgments routinely require one parent to maintain a life insurance policy with the former spouse, or the children, named as beneficiary, specifically to secure ongoing child support or maintenance obligations if that parent dies before the payments are complete.
If that describes your judgment, do not update that particular beneficiary designation just because you’re cleaning out every other reference to your ex. Removing a beneficiary that your own divorce judgment requires you to keep in place is a violation of a court order, and family court judges do not treat it lightly. The practical approach is to go through every document and designation individually against the terms of your actual judgment, rather than applying one blanket rule to everything at once.
Laid out side by side, the gap between “Wisconsin law handled it” and “you still need to handle it” becomes clear fast:
| Document or designation | Changed automatically by Wisconsin law? | What you still need to do |
|---|---|---|
| Will (gifts and fiduciary nominations to ex-spouse) | Yes, once final — Wis. Stat. § 854.15 | Write a new will; name a guardian and new executor |
| Revocable living trust (trustee, beneficiary terms) | Partially, and unreliably on paper | Formally amend or restate; retitle any remaining assets |
| Financial power of attorney | Yes, at filing — Wis. Stat. § 244.10(2)(c) | Name a new agent immediately; don’t wait for the decree |
| Health care power of attorney | Only once final — Wis. Stat. § 155.40(2) | Sign a new one now if you don’t want the old agent deciding during the case |
| 401(k), pension, group life insurance | No — ERISA preempts state law | File a new beneficiary form with the plan administrator or insurer |
| IRAs, individual life insurance, POD/TOD accounts | Usually, under governing-instrument rules | Confirm directly with the institution; don’t assume |
| Beneficiaries required by your divorce judgment | No — the court order controls | Leave in place exactly as ordered |
Many people who diligently update their estate plan right after a divorce never touch it again, and then remarry a few years later without realizing the plan needs another full pass. A new marriage brings its own set of defaults under Wisconsin's Marital Property Act, potential stepchildren, and an elective share your new spouse may be entitled to regardless of what an old will says. If you're blending a new family with children from the first marriage, the planning questions multiply quickly: who inherits the house, whether a trust should protect children from the first marriage while still providing for a new spouse, and how to avoid the exact kind of outdated-document problem that just cost you time and money once already. Our blended family estate planning guide walks through how Wisconsin families structure a plan that protects both a new spouse and children from a prior relationship.
Doing nothing after a Wisconsin divorce doesn't mean your old plan simply freezes in place; it means different pieces of it break on different timelines without you noticing. Your former spouse loses authority under your financial power of attorney the day you filed, which is fine if you've already replaced it and a real problem if you haven't. Your former spouse keeps authority under your health care power of attorney until the day the divorce is final, and keeps whatever Section 854.15 doesn't reach, like a 401(k) beneficiary designation, forever, unless you personally change it. The pattern is rarely “ex-spouse inherits everything”; it's usually one or two specific documents nobody thought to revisit, discovered by a grieving family at the worst possible time. Our guide to avoiding probate covers how an outdated or incomplete plan tends to land in court either way.
Updating an estate plan after divorce is almost always less work than building one from scratch, since the inventory of what you own and who you'd name is usually already clear from the divorce itself. A new will, updated powers of attorney, and a trust amendment or restatement are typically quoted as a flat fee before you decide anything, scoped to what's actually changing rather than priced as if you were starting over. Most of the delay in finishing isn't legal drafting; it's tracking down every account, policy, and plan administrator to file the beneficiary paperwork. Starting that list the week your decree is signed, rather than months later, is what keeps the whole process from dragging on.
Partially. Under Wis. Stat. § 854.15, once your divorce is final, any gift to your former spouse or their relatives in your existing will is revoked automatically, and so is any nomination of them as personal representative or guardian. It does not rewrite the rest of the will, name a new guardian for your children, or touch anything outside that one document, so you still need a new will.
Not cleanly. Wisconsin's automatic revocation statute reaches many governing instruments, but a trust is a contract-like document that often needs its own amendment to actually remove a former spouse as trustee, successor trustee, or beneficiary, and assets already titled in the trust still need the trust's terms to be correct on paper, not just assumed revoked.
Under Wis. Stat. § 244.10(2)(c), your spouse's authority as your financial agent terminates the moment an action for divorce, annulment, or legal separation is filed, not when the divorce is finalized. That leaves a gap until you sign a new power of attorney naming someone else, which is worth doing immediately rather than waiting for the case to close.
Yes, if it says so expressly. Wis. Stat. § 854.15 includes an exception for governing instruments, court orders, or marital settlement agreements that state a contrary intent, which matters most when your judgment requires you to keep a former spouse as a life insurance beneficiary to secure child support or maintenance payments.
Yes, and this is the step people skip most often. Federal ERISA law preempts Wisconsin's automatic revocation statute for employer retirement plans, so a former spouse named on a 401(k) or pension before the divorce can still inherit it unless you file a new beneficiary form directly with the plan administrator or insurer.
Start before the divorce is even final. Your financial power of attorney already changed the day you filed, so naming a new agent shouldn't wait. The will, trust, health care directive, and beneficiary designations are best handled within a few weeks of the final judgment, while the terms of the settlement are still fresh and any required beneficiary provisions are easy to confirm.
Updating your estate plan after a divorce in Wisconsin isn't one task; it's a set of documents and designations running on different clocks, some fixed by statute, some fixed only by you, and a few that your own judgment may require you to leave exactly as they are. The pattern we see most often isn't a plan that was never touched; it's a plan that was touched partway, with a 401(k) form or a trust amendment quietly left behind. Schedule a free consultation and we'll go through your specific documents against your specific judgment, in plain English, and quote a flat fee before you decide anything.
Thirty minutes, no obligation. You’ll leave knowing exactly what your family needs and what it costs.
