If you believe a family member’s will doesn’t reflect their true wishes — or that something went wrong when it was created — you may have grounds to contest it. But contesting a will in California is not as simple as disagreeing with how assets were divided. You need legal standing, a valid legal basis, and you need to act within a strict deadline. Here’s what the process looks like from start to finish.
Quick Answer: Contesting a Will in California
To contest a will in California, you must have legal standing (typically as an heir or prior beneficiary), file a contest before the deadline, and prove at least one valid legal ground — such as lack of testamentary capacity, undue influence, fraud, or improper execution. A successful contest can result in the will being thrown out entirely or specific provisions being invalidated.
Who Can Contest a Will in California?
Not everyone can challenge a will — you must have “standing,” which means a direct financial interest in the outcome. In California, the following people generally have standing to contest:
Heirs at law. These are the people who would inherit under California’s intestate succession laws if there were no valid will — typically a spouse, children, or other close relatives.
Beneficiaries named in a prior will. If a previous version of the will left you more, or named you at all, you have standing to challenge a later version that cut you out.
Beneficiaries named in the current will. Even if the current will names you, you may have standing to challenge specific provisions that affect your share.
People who are not heirs and were not named in any version of the will generally do not have standing, regardless of what they believe the deceased would have wanted.
Valid Grounds to Contest a Will in California
Disagreeing with how the deceased divided their estate is not a legal basis for a will contest. You need to prove one of the following recognized grounds:
Lack of Testamentary Capacity
The person who made the will (the testator) must have been of sound mind at the time it was signed. California law requires that the testator understood: the nature of making a will, the extent of their property, who their natural heirs were, and how the will distributes their assets. If the person had dementia, severe cognitive impairment, or was mentally incapacitated at the time of signing, the will may be invalid.
Undue Influence
This is one of the most common grounds for a will contest in California. Undue influence occurs when someone used pressure, manipulation, or coercion to override the testator’s free will and substitute their own. It often involves a caregiver, a new romantic partner, or a family member who isolated the deceased and influenced changes to the will late in life. Proving undue influence requires showing that the influencer had a confidential relationship with the testator, was in a position to exert influence, actually exerted that influence, and that the resulting will reflects that influence rather than the testator’s true wishes.
Fraud or Forgery
If the testator was deceived into signing a document they didn’t know was a will, or if the will or signature was forged, it can be contested on grounds of fraud. This includes situations where someone misrepresented material facts to convince the testator to change their will.
Improper Execution
California has specific requirements for how a will must be signed and witnessed. A standard will must be signed by the testator (or by another person at the testator’s direction) and witnessed by at least two adults who were present at the same time. If those formalities weren’t followed, the will may be invalid regardless of what the testator intended.
Revocation
A later, valid will automatically revokes a prior one. If you believe a more recent will exists that supersedes the one being probated, that can be the basis of a challenge. Alternatively, a will can be revoked by physical destruction with intent to revoke.
The Deadline to Contest a Will in California
Timing is critical. In California, you generally have until the later of: 120 days after the date the court admits the will to probate, or 60 days after the court clerk mails you a copy of the will with notice that it has been admitted. Miss this deadline and your right to contest is almost certainly gone. Do not wait.
What a Will Contest Does to Your Inheritance Timeline
A contested will significantly delays the probate process. While a typical California probate takes 12 to 18 months, a contested case can take several years. During that time, the estate is largely frozen. Beneficiaries — including those who expect to win the contest — may be waiting without access to any funds.
If you’re a beneficiary in a contested estate and need money now, a probate advance may be available depending on the circumstances. Learn how probate advances work and whether your situation qualifies.
How to File a Will Contest in California
A will contest is filed in the Superior Court of the county where the decedent lived. You file a written objection — called a “contest” — with the probate court. The contest must state your grounds clearly and be supported by evidence. The probate proceeding is then put on hold while the contest is litigated, often as a separate civil trial.
You should not attempt to contest a will without an attorney. The procedural requirements are strict, the deadlines are unforgiving, and the other side — often the executor and the primary beneficiary — will almost certainly have legal representation. Most probate litigators work on a contingency basis for will contests, meaning they take a percentage of the recovery rather than charging upfront.
What Happens If Your California Will Contest Succeeds?
If the court invalidates the will, the estate is distributed as if the will never existed. That means either a prior valid will controls, or — if no valid will exists — the estate passes under California’s intestate succession laws. The California inheritance laws determine who inherits and in what proportions when there is no valid will.
If only a specific provision is found invalid (rather than the entire will), the rest of the will typically stands and only the challenged portion is struck.
What Happens If Your California Will Contest Fails?
If the court upholds the will, the original distribution plan stands. You may also be responsible for the other party’s attorney fees in some circumstances, particularly if the contest was found to have been brought in bad faith. Many wills also include “no-contest clauses” (also called in terrorem clauses), which can disinherit a beneficiary who challenges the will and loses. California enforces these clauses in specific circumstances, so check whether the will contains one before filing.
Frequently Asked Questions
How much does it cost to contest a will in California?
Costs vary widely depending on the complexity of the case and whether it goes to trial. Attorney fees for a will contest can range from $10,000 to well over $100,000. Many attorneys handle will contests on contingency, but not all. Court filing fees, expert witness fees (such as medical experts testifying about capacity), and deposition costs all add up. Before filing, have an honest conversation with your attorney about the likely cost versus the potential recovery.
Can I contest a will if I was left out entirely?
Yes, if you have standing — meaning you would have inherited under a prior will or under California intestate law if no valid will existed. Being omitted from a will is not by itself grounds for a contest. You need a valid legal basis, such as undue influence or lack of capacity, in addition to standing.
What Is a No-Contest Clause in a California Will?
A no-contest clause states that any beneficiary who challenges the will forfeits their inheritance. California enforces these clauses only against beneficiaries who contest without “probable cause” — meaning if you had a reasonable basis to believe the challenge was valid, you are generally protected from forfeiture even if you lose. If you have no valid legal basis for a contest and you’re named in the will, filing anyway could cost you what you were already going to receive.
How long does a will contest take in California?
Simple contests may be resolved in 6 to 12 months. Contested cases that go to trial can take two to four years or longer. During that time, the estate cannot be fully administered and distributions are on hold.
Does Contesting a Will Stop California Probate?
Yes, in most cases. Filing a will contest places a hold on the probate proceeding until the contest is resolved. The executor can still take steps to preserve estate assets, but distributions to beneficiaries are typically frozen. If you’re a beneficiary in a prolonged contested estate and need funds in the meantime, apply for a California probate advance.
Should You Contest a Will in California?
Contesting a will in California is a legitimate legal option when there’s a real basis to believe the will doesn’t reflect the deceased’s true intent. But it’s not something to pursue lightly. The costs are significant, the timeline is long, and the outcome is uncertain. If you believe you have valid grounds, consult a probate litigation attorney immediately — the deadline to file can arrive faster than you expect.
