A family member may say that a house, account, or share of an estate will eventually belong to someone who provides care or other assistance. After the person dies, the surviving family may discover that the will or trust does not contain the expected gift. A California promised inheritance raises questions about whether there was an enforceable agreement, what evidence supports it, and whether action must be taken before a deadline expires. For Southern California families, the distinction between an expression of future intent and a binding commitment is central to evaluating the situation.

Probate Code section 21700 identifies ways to establish certain contracts concerning wills and other inheritance arrangements made after the statute became effective. These include specified language in an instrument, a signed writing evidencing the contract, and certain agreements or promises established by clear and convincing evidence that are enforceable in equity. An oral promise is therefore not automatically enforceable, but the absence of a conventional signed contract does not end every inquiry. The date of the agreement also matters because the statute directs that older contracts be evaluated under the law previously applicable to them.

A useful factual review begins with the actual words used, who heard them, and whether the parties described an exchange rather than a possible future gift. Statements such as an intention to remember someone in an estate plan may present different issues from a specific commitment tied to identified services or obligations. Relevant materials can include letters, messages, signed notes, and records showing what the claimant did in response to the alleged agreement. Organizing those materials chronologically helps distinguish contemporaneous evidence from conclusions family members reached only after learning what the estate plan provides.

Timing requires separate attention even when the evidence appears substantial and relatives remain willing to discuss the disagreement. Code of Civil Procedure section 366.3 generally provides a one-year period after death for an action enforcing a claim to distribution based on a decedent's promise or agreement. The statute sharply restricts tolling and extensions, so a claimant should not assume that negotiations or the ongoing administration of an estate preserve the claim. Counsel should evaluate the applicable deadline and procedural requirements early rather than waiting until distributions are being finalized.

Another misunderstanding can arise when spouses sign similar wills and family members assume that neither spouse may later change the arrangement. Probate Code section 21700 expressly states that executing a joint will or mutual wills does not create a presumption of a contract not to revoke them. A surviving spouse's authority and any enforceable contractual restriction therefore require review of the actual documents and evidence rather than an inference based only on matching provisions. Families should preserve any separate agreement or explanatory correspondence instead of assuming that the wills themselves answer every question.

A California promised inheritance dispute is easier to evaluate when the claimed promise, supporting evidence, requested relief, and relevant dates are identified separately. During planning, people intending to exchange services or other commitments for a future inheritance can seek advice about documenting the arrangement and coordinating it with the estate plan. That discussion should address the promised property, each party's obligations, and what happens if circumstances change before death. This article provides general information, not legal advice.
