Spousal rights in probate give a surviving husband or wife a legally guaranteed share of the deceased partner’s estate, along with housing, personal property, and support protections, even when the will leaves them nothing. The core right is the elective share, which lets you reject the will and take a statutory portion instead. Alongside it sit homestead, exempt property, and family allowances, pretermitted-spouse protection for wills written before the marriage, and federal estate tax benefits that can be worth millions. Most of these rights have hard deadlines, and missing one usually means losing it for good.
The Elective Share
The elective share lets a surviving spouse walk away from the terms of the will and instead claim a fixed portion of the estate set by state law. Traditionally that portion is one-third, though some states set it at one-half. The right exists because the law treats marriage as an economic partnership and prevents one spouse from funneling everything to children from a prior relationship, a charity, or anyone else.
States that have adopted the Uniform Probate Code use a sliding scale tied to the length of the marriage. A spouse married for one year can claim roughly 3 percent of the estate; after fifteen years the share reaches 50 percent. The reasoning is that longer marriages typically build more joint wealth, so the share should reflect that.
To take the elective share you have to file a petition in probate court within a tight window. The typical deadline is nine months after the date of death or six months after the will is admitted to probate, whichever comes later. Miss it and the right is almost always gone. Extensions are rare, and courts do not treat late filings generously. If there is any chance you will need to elect against the will, bring a probate attorney in well before the deadline.
What Counts Toward the Estate
The elective share would be easy to defeat if it applied only to assets passing through the will. Someone could move everything into a revocable trust, title accounts jointly with a child, or name non-spouse beneficiaries on life insurance and retirement accounts, leaving a near-empty probate estate behind. The augmented estate rule closes that loophole.
Under the UPC framework, the augmented estate pulls in revocable trust assets the deceased could still change or cancel, joint tenancies with rights of survivorship, and life insurance and retirement proceeds with named beneficiaries. It also captures large gifts made within two years before death, which prevents deathbed transfers designed to shrink the estate.
One detail catches many surviving spouses off guard. In UPC states, the spouse’s own assets count toward the augmented estate total too. The elective share percentage applies to the combined value, and whatever the spouse already owns is credited against what the share would otherwise provide. A spouse who already holds substantial marital wealth may find the elective share reduced or fully satisfied by what is already in their name.
Community Property States Work Differently
Nine states follow community property rules instead: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. In these states most property acquired during the marriage already belongs equally to both spouses, so an elective share is largely unnecessary.
The surviving spouse automatically keeps their half of all community property. The deceased spouse can direct only their own half through the will. Separate property, meaning assets one spouse owned before the marriage or received as a gift or inheritance, belongs solely to that spouse and can be left to anyone.
The practical difference matters. In a common law state, a surviving spouse who was cut out must take affirmative legal action within the deadline to claim anything. In a community property state, the 50 percent ownership interest in marital assets exists automatically. If you and your spouse have lived in both types of states during the marriage, which rules apply to which assets can get complicated, and that question is worth sorting out with an estate planning attorney while both spouses are alive.
Homestead, Exempt Property, and Family Allowance
Separate from the elective share, probate law gives the surviving spouse three additional protections meant to keep daily life stable while the estate is being settled. These take priority over almost all other claims against the estate, including general creditors.
The homestead allowance protects the right to stay in the family home or receive a set dollar amount from the estate. Under the UPC that amount is $22,500. Individual states set their own figures, which can range from a few thousand dollars up to amounts that reflect local real estate values. The homestead allowance is a guaranteed minimum off the top, not a mortgage payoff.
The exempt property allowance covers tangible personal items such as furniture, a vehicle, and household appliances. The UPC sets this at $15,000 in personal property measured as of the date of death. If the estate does not contain enough qualifying items, the spouse can claim other estate assets to make up the difference.
The family allowance provides cash for living expenses during administration. The UPC does not specify a dollar figure; it tells courts to award a reasonable amount based on the family’s previous standard of living. The allowance can run up to a year and may be paid in a lump sum or in monthly installments. Minor children the deceased was supporting are also entitled to the family allowance alongside the surviving spouse.
If the Will Was Written Before the Marriage
A common situation: someone writes a will, later marries, and dies without updating the document to include the new spouse. The law does not assume the omission was intentional. Under the pretermitted spouse doctrine, the surviving spouse is presumed to have been left out by accident, and the court awards them the share they would have taken if the deceased had died with no will at all.
That intestate share can be large. Under the UPC, a surviving spouse inherits the entire estate when the deceased leaves no children or surviving parents. When the deceased had children from a prior relationship, the spouse takes the first $150,000 plus half the remaining balance. State figures vary, but the pretermitted spouse often ends up with far more than the will’s named beneficiaries expected.
This protection differs from the elective share in a key way. The elective share requires a deliberate choice and a filed petition. Pretermitted spouse protection is automatic once the court determines the will predates the marriage and does not provide for the new spouse. If there is evidence the omission was intentional, or if the spouse was provided for through transfers outside the will, the claim can be denied. The burden of proving intentional omission rests on whoever is challenging the spouse’s right.
When These Rights Are Lost
Spousal protections are strong but not unconditional. Several circumstances cut them off entirely.
The slayer rule bars anyone who intentionally and unlawfully kills the deceased from inheriting. In most jurisdictions the killer is treated as having predeceased the victim, which wipes out every inheritance right. A criminal conviction is the clearest path to triggering it, but many states allow a civil court to apply the rule on a preponderance of the evidence standard, even without a criminal case.
Divorce ends spousal rights, but timing is everything. If a spouse dies while the divorce is still pending and no final decree has been entered, most states treat the survivor as a legal spouse with full inheritance rights. A separation agreement or filed divorce petition alone generally does not sever probate protections. Only a finalized divorce does.
Spouses can also waive these rights voluntarily. Waivers appear most often in prenuptial and postnuptial agreements. Under the UPC, a waiver must be in writing, signed voluntarily, and executed after both parties have had a fair opportunity to understand each other’s finances. Full financial disclosure is central. A waiver signed without knowing what is being given up is the kind of agreement courts set aside. Courts can also refuse to enforce a waiver if the result would be unconscionable at the time of death. Independent counsel on each side when the agreement is drafted is the best protection against a later challenge.
Federal Estate Tax Benefits for the Surviving Spouse
Two federal rules can be worth more to a surviving spouse than any state-law protection.
The first is the unlimited marital deduction. Any property passing to a surviving U.S. citizen spouse is fully exempt from federal estate tax, no matter the amount. A $50 million estate left entirely to a citizen spouse owes zero federal estate tax at the first death. Tax is deferred until the surviving spouse later dies and the assets pass to the next generation.
The second is portability. For 2026, the federal estate tax exemption is $15,000,000 per person. If one spouse dies without using the full exemption, the unused portion can transfer to the survivor, letting a married couple shelter up to $30 million from federal estate tax. Claiming portability requires the executor to file IRS Form 706 within nine months of death, with an automatic six-month extension available. For estates that are not otherwise required to file, the executor has up to five years from the date of death to file solely for the portability election.1Internal Revenue Service. Estate Tax
Portability is one of the most valuable and most frequently missed tools in estate planning. When a spouse dies and the estate falls below the filing threshold, families often assume no return is needed. That is true for tax purposes, but skipping the return forfeits the deceased spouse’s unused exemption permanently. Given that future exemption amounts can change, locking in today’s figure through a timely filing is cheap insurance.2Internal Revenue Service. What’s New – Estate and Gift Tax
Non-Citizen Surviving Spouses
The unlimited marital deduction does not apply when the surviving spouse is not a U.S. citizen. Without additional planning, assets passing to a non-citizen spouse are subject to federal estate tax the same way they would be if passing to any other beneficiary. The concern is that a non-citizen spouse could take a tax-free inheritance abroad, permanently removing those assets from the U.S. tax base.
A Qualified Domestic Trust, or QDOT, is the standard workaround. Assets placed in a properly structured QDOT qualify for the marital deduction, deferring estate tax until the surviving spouse receives distributions of principal or dies. The trust must have at least one U.S. citizen or domestic corporation serving as trustee, with authority to withhold tax on principal distributions. The IRS imposes additional security requirements when QDOT assets exceed $2 million, and the restrictions fall away if the surviving spouse later becomes a U.S. citizen, provided they were a U.S. resident continuously from the decedent’s death through citizenship and no taxable distributions were made in the meantime.3Internal Revenue Service.
