Marriage does not override a will in the sense of erasing it, but it does hand your new spouse a package of legal rights that can redirect a large share of your estate no matter what the document says. A spouse left out of a will written before the wedding can usually claim the same share they would have received if you had died with no will at all. On top of that, nearly every state lets a surviving spouse reject the will’s terms and take a statutory minimum instead. And some of the biggest assets, like retirement accounts and life insurance, were never controlled by the will to begin with.
The Omitted Spouse Rule
If you wrote your will before getting married and never updated it, probate law in most states treats your new spouse as accidentally left out. The label is “omitted spouse” or “pretermitted spouse,” and the remedy is direct: the spouse receives the share they would have taken under intestacy, as if no will existed. Depending on the state and who else survives you, that can range from roughly one-third of the estate up to the whole thing when there are no surviving children or parents.
The Uniform Probate Code, adopted in some form by roughly half the states, recognizes three narrow exceptions. The omitted spouse gets no extra share if the will shows the omission was intentional, if a prenuptial or postnuptial agreement already addresses the spouse’s share, or if the deceased provided for the spouse outside the will through transfers like a trust or joint account and there is evidence those transfers were meant to substitute for a bequest. Outside those situations, the spouse’s claim takes priority over the beneficiaries named in the will, and the existing bequests shrink proportionally to fund it.
This is how quiet estate-plan failures happen. Someone writes a will leaving everything to their children, marries years later, and never touches the document. The new spouse walks into probate court and claims an intestate share, and the children’s inheritance shrinks. The will was not thrown out. It just could not do what the writer assumed it would.
The Elective Share: Rejecting the Will Outright
Even when a will does mention the surviving spouse, most states let that spouse refuse what the will offers and claim a statutory minimum instead. This is the elective share, and it exists specifically to stop one spouse from disinheriting the other.
The percentages vary. States following the Uniform Probate Code use a sliding scale tied to the length of the marriage, starting at 3% after one year and rising to 50% after fifteen years. Other states set a flat fraction, commonly one-third or one-half, regardless of how long the marriage lasted. Georgia has no elective share statute at all.
The reach of the calculation matters as much as the percentage. In states that follow the UPC’s “augmented estate” approach, the elective share applies to the total value of everything the deceased owned or controlled, not just what passes through probate. That means life insurance proceeds, retirement account balances, revocable trust assets, and jointly held property all count toward the base. A plan that leaves the spouse a token amount in the will while routing everything else through trusts and beneficiary designations will not necessarily escape the elective share, because the state may pull those assets back into the calculation.
Community Property States Work Differently
Nine states use community property rules rather than common law property rules, and the answer to whether marriage overrides a will looks different there. In community property states, nearly everything earned or acquired during the marriage belongs equally to both spouses regardless of whose name is on the title. When one spouse dies, the will can only direct that spouse’s half of the community property. The surviving spouse already owns the other half outright, and no will can reach it.
Property owned before the marriage, along with gifts and inheritances received individually, generally stays separate and can be distributed freely by will. Wages, investment returns, and purchases made with marital funds fall into the community pot.
Common law states determine ownership by title, which gives the will more room to direct assets to specific people. The trade-off is that the surviving spouse’s protection there depends entirely on the elective share rather than an automatic half-ownership claim.
Interstate moves create their own complications. Some community property states recognize “quasi-community property,” meaning assets acquired while the couple lived in a common law state that would have been community property if they had lived in a community property state at the time. Where that concept applies at death, the survivor may be entitled to half of those assets even though they were originally earned under common law rules. Not every community property state applies the concept at death, so a late-in-life move can leave real uncertainty about who owns what.
Assets Your Will Never Controlled
A separate problem is that some of the largest pieces of an estate were never under the will’s control in the first place. Life insurance policies, 401(k) plans, IRAs, brokerage accounts with transfer-on-death designations, and bank accounts with payable-on-death beneficiaries all pass directly to whoever is named on the account. The will has no effect on them. You can leave everything to your children in your will, but if an ex-spouse is still named on a life insurance policy, the ex-spouse gets the payout.
ERISA Gives Your Spouse Automatic Rights to Employer Retirement Plans
Federal law adds a layer for employer-sponsored retirement plans like 401(k)s and pensions. Under ERISA, your surviving spouse is automatically entitled to inherit your plan benefits unless the spouse signs a written waiver consenting to a different beneficiary. That waiver must acknowledge the effect of giving up the benefit and must be witnessed by a plan representative or notary public.1Office of the Law Revision Counsel. 29 U.S. Code 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity Simply naming someone else on the beneficiary form is not enough. Without the notarized spousal consent, the plan administrator pays the spouse regardless of what the form or the will says.
For traditional pension plans, the default is a qualified joint and survivor annuity, meaning the pension continues paying the surviving spouse at least half of the benefit amount for life.2U.S. Department of Labor. FAQs About Retirement Plans and ERISA Waiving that benefit requires the same written, witnessed consent.
IRAs are the exception. They are not governed by ERISA, so there is no federal spousal-consent requirement when naming a beneficiary. State elective share law may still give the surviving spouse a claim on IRA assets, but the federal consent mandate does not apply.
Second Marriages Feel the Effect Hardest
The clash between a pre-existing will and a new marriage hits hardest when there are children from a prior relationship. The typical setup is a will leaving everything to those children, written long before the second wedding. When the parent remarries without updating anything, the new spouse gains omitted spouse rights that directly reduce what the children inherit. Updating the will to name the new spouse does not fully solve it either, because the elective share creates a floor the will cannot go below.
A will alone cannot both meet the spouse’s statutory minimum and preserve the full inheritance the children were expecting. The standard workaround is a trust, often a QTIP trust, that pays income to the surviving spouse for life while preserving the principal for the children afterward. Without that kind of structure, the default rules favor the surviving spouse heavily, and in a modest estate the children can end up with little.
How to Keep Marriage From Redirecting Your Will
A prenuptial agreement is the most reliable way to set what a surviving spouse will receive, because it can waive the elective share, the omitted spouse claim, and other statutory rights before the marriage begins. Courts generally enforce prenups when both parties made full financial disclosures, neither was pressured, and both had the chance to consult independent counsel. Duress or hidden assets leave the agreement open to challenge.
Postnuptial agreements do the same job after the wedding, but courts scrutinize them more closely because the parties are already in the relationship. Separate counsel, complete financial disclosure, and terms a court would consider fair are typical requirements. An agreement that strips one spouse of everything while the other keeps it all is unlikely to survive.
Either type of agreement has to specifically address what happens at death, not just divorce. A prenup that only covers divorce may leave the surviving spouse free to claim an elective share or omitted spouse rights anyway.
Beyond the agreement itself, updating the estate plan after marriage means treating it as a unit rather than a single document:
- Revise the will to name your spouse where you want them named, update your executor, and adjust bequests to other beneficiaries. If children from a prior relationship are in the picture, consider whether a trust structure serves your goals better than an outright bequest.
- Review every beneficiary designation. Life insurance policies, retirement accounts, and payable-on-death or transfer-on-death registrations all override the will and must be updated separately.
- For ERISA-governed retirement plans, get your spouse’s written, witnessed consent now if you want someone else as beneficiary.1Office of the Law Revision Counsel. 29 U.S. Code 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity
- Update powers of attorney and healthcare directives. Marriage does not automatically make your spouse your decision-maker in every state.
- Check property titles. Jointly held property may pass by survivorship outside the will, and that needs to match your plan rather than contradict it.
Having an attorney update a will and review beneficiary designations costs far less than the legal fees, family conflict, and misdirected assets that follow an outdated plan. The omitted spouse doctrine and elective share exist because so many people skip this step, and the cheapest place to fix it is not probate court.
