When a married person dies, the surviving spouse is not always limited to whatever the will says. In many states, the law gives a surviving spouse separate statutory rights that may exist even when an estate plan tries to leave little or nothing to that spouse. Those rights often include an elective share, rights in exempt property or homestead, family allowance claims, and related probate remedies. The details vary sharply by state, which is why these disputes can become complex very quickly.
This post explains the basics of elective share law, how augmented estates work, when a waiver may change the analysis, and how surviving spouse claims are often evaluated in real probate disputes. If you’re looking for a broader overview of inheritance litigation, it may help to start with this guide to probate and estate disputes more generally. If you want a more introductory overview focused just on spouse protections, this plain-language article on what rights a surviving spouse may have can also be useful.

An elective share is a statutory right that lets a surviving spouse claim a defined portion of the deceased spouse’s estate, even if the will says otherwise. Cornell’s Legal Information Institute explains that elective share law exists to prevent a spouse from being disinherited, and that in many states the share is a fixed fraction, often tied to the probate estate or a broader statutory formula.

In simple terms, an elective share is the law’s way of asking: What minimum economic protection, if any, does a surviving spouse receive despite the decedent’s estate plan?
That question matters because modern estate plans often move wealth outside probate. Assets may pass through revocable trusts, transfer-on-death designations, joint accounts, retirement plans, and life insurance. If a state looked only at the probate estate, it could be relatively easy to leave a spouse with very little while transferring substantial wealth elsewhere. That concern is one reason some states use broader estate concepts such as the augmented estate or elective estate. Uniform Probate Code materials from the Uniform Law Commission
The elective share is only one piece of the picture. Depending on the state, a surviving spouse may also assert rights involving:
Those rights do not operate the same way in every jurisdiction. For example, California handles many spousal property issues through community property rules and procedures that may avoid a full probate administration in some cases, rather than through the classic elective-share model common in separate-property states.

That variation is one reason surviving spouse disputes often turn into a state-specific statutory interpretation exercise rather than a simple reading of the will.
