In nearly every state, a husband cannot leave his wife out of his will and make it stick. He can write the document that way, but the law gives a surviving wife the right to reject what the will provides and claim a statutory share of the estate instead. Community property rules, federal retirement account laws, and homestead protections add further layers. The practical question is rarely whether a wife can be disinherited, but how much she is entitled to claim and how quickly she has to act.
The Elective Share in Common Law States
Roughly 41 states follow a common law property system, and each of them gives a surviving spouse an elective share (sometimes called a forced share). A wife who has been left out of the will, or left less than the statute guarantees, can file to take the elective share instead. She does not have to prove the omission was unfair or malicious. The right exists by statute, and claiming it is a legal election.
The fraction varies by state. The traditional share in many states is one-third of the estate; some set it at one-half. Other states tie the share to the length of the marriage under a model drawn from the Uniform Probate Code, so a short marriage yields a small percentage and a marriage of 15 years or more can reach 50 percent of the marital-property portion of the estate.
The base the percentage is applied to matters as much as the percentage itself. Some states calculate the elective share only against the probate estate, meaning assets that actually pass through the will. Others use an “augmented estate,” which pulls in non-probate assets like trust distributions, joint accounts, and gifts made shortly before death. The augmented estate is much harder to work around, because retitling assets or moving them into beneficiary-designated accounts doesn’t shrink the pool a surviving spouse can claim against.
Community Property States
Nine states use a different system entirely. In Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin, most income earned and property acquired during the marriage belongs equally to both spouses, regardless of who earned it or whose name is on the title.1Internal Revenue Service. Publication 555 (12/2024), Community Property A husband in one of these states already owns only half of the community property. He can leave his half to whomever he chooses. He has no authority over his wife’s half, because she already owns it.
Separate property is treated differently. Assets one spouse owned before the marriage, or received individually as a gift or inheritance during the marriage, generally stay separate and can be left to anyone. Fights often break out over whether particular assets stayed separate or became commingled over the years.
Retirement Accounts and Assets the Will Doesn’t Control
A will only controls the probate estate. Much of what a couple owns typically passes outside probate through beneficiary designations or joint ownership, and those transfers happen regardless of what the will says.
Employer-sponsored retirement plans carry a federal spousal protection on top of state law. Under ERISA, the spouse of a married 401(k) or pension participant is automatically the beneficiary. To name anyone else, the participant needs a written spousal consent that is either witnessed by a plan representative or notarized.2Office of the Law Revision Counsel. 29 U.S. Code 1055 – Requirement of Joint and Survivor Annuity and Preretirement Survivor Annuity Without that signed waiver, the surviving spouse takes the account.
IRAs are the trap. They do not carry the same federal protection. An IRA passes to whoever is named on the beneficiary form, and no spousal consent is required to name someone else. A husband can list a sibling, a child from a prior marriage, or anyone else, and his wife may never know. Some states fill the gap partway, but the federal backstop that covers 401(k)s does not apply.
Other assets that move outside the will and follow their beneficiary designations or titling:
- Life insurance proceeds, which go to the named beneficiary.
- Payable-on-death bank accounts, which transfer directly to the named individual.
- Transfer-on-death brokerage and investment accounts.
- Real estate held in joint tenancy with right of survivorship, which passes automatically to the surviving owner.
Checking the beneficiary designation on every retirement and financial account is one of the most practical protective steps a spouse can take.
Wills Written Before the Marriage
A separate rule applies if the husband wrote his will before the marriage and never updated it. Most states presume the omission was an oversight rather than a deliberate choice. Under “pretermitted spouse” or “omitted spouse” statutes, a surviving spouse who married the testator after the will was signed can claim the share they would have received if there had been no will at all. That intestate share is often one-third to one-half of the estate, depending on the state and whether the deceased left children.
The protection typically disappears when the omission was clearly intentional, such as a will that expressly states nothing will pass to any future spouse, or a prenuptial agreement waiving inheritance rights. A will that simply predates the marriage and never mentions the spouse is the exact scenario the statute is written for.
When a Wife Can Actually Be Disinherited
Disinheritance does succeed in some situations. The most reliable route is a prenuptial or postnuptial agreement in which the wife voluntarily waives her elective share or community property rights. Courts enforce these, but they scrutinize them because the stakes are high. To hold up, a waiver generally must be:
- Written and signed. Oral waivers of inheritance rights are not enforceable.
- Voluntary, with no coercion or duress. A prenup produced the night before the wedding invites a challenge.
- Backed by full financial disclosure, so both spouses knew what they were giving up.
- Signed with a real opportunity for each side to consult independent counsel.
Separation Is Not Divorce
Legal separation usually does not end a spouse’s inheritance rights. Couples who have lived apart for years may still hold their elective share rights if no divorce decree has been entered. Some states carve out exceptions for abandonment, post-separation adultery, or a formal judicial separation, but the general rule surprises people: until the divorce is final, a separated spouse can still elect against the will. This matters when one spouse dies mid-divorce.
Homestead and Family Allowance
Many states layer on baseline protections beyond the elective share. Homestead laws in a number of states keep the marital home from being left entirely to someone else and guarantee the surviving spouse the right to keep living there. Family allowance statutes provide a reasonable living allowance during probate that takes priority over most creditor claims and other bequests. Some states also grant an exempt property allowance covering household furnishings, vehicles, and personal effects. The dollar amounts are modest, but the point is to keep a surviving spouse from being left homeless or without cash while the estate is settled.
How to Claim the Share
The elective share is not automatic. A surviving spouse has to file a petition in the probate court to claim it. Doing nothing means accepting whatever the will provides, even if the will provides nothing.
Deadlines are strict. The window varies by state, but a common framework gives the surviving spouse nine months from the date of death or six months from the appointment of the personal representative, whichever is later. Some states set shorter windows. Missing the deadline forfeits the right permanently, and courts rarely grant extensions for not knowing about it.
Because the filing requires calculating the estate’s value under the applicable state formula, and because the amount at stake is usually substantial, it is worth hiring a probate attorney early rather than waiting to see what the will contains during the formal probate process. A spouse who suspects disinheritance should consult counsel soon after the death, while there is still time to act.
