We also offer contingency representation, which means you pay nothing unless we recover compensation.

What It Means to Contest a Will or Trust in California

When contesting a will or trust, you formally challenge its legal validity in court. In other words, you ask a judge to determine whether the will or trust’s creator (for a will, a “testator,” for a trust, a “grantor” or “settlor”) followed California law when they created the document. 

After a successful contest, the court may:

  • Discard the document,
  • Remove certain provisions, or 
  • Reinstate an earlier legally valid version of the document. 

Although a will or trust challenge requires filing papers with a court, you can still settle outside the courtroom.

When Can You Contest a Will or Trust in California? 

To contest a will or trust, you must have specific legal grounds—reasons authorized by law. Many legal grounds that a person can use to challenge a will overlap with reasons they can challenge a trust, including:

  • Lack of capacity. Claiming that the creator did not understand what they were doing when they made the will or trust. For example, someone who had Alzheimer’s disease, dementia, or another condition that impaired their judgment may have lacked mental capacity or not been “of sound mind.”
  • Undue influence. Claiming that someone pressured, manipulated, or coerced the creator to change their estate plan in the influencer’s favor. Courts sometimes infer undue influence when the creator and alleged influencer had a confidential relationship, the influencer played an active role in creating the document, and the document reflects an unexpected benefit to the influencer.
  • Fraud or forgery. Claiming someone tricked the testator or grantor into signing the document, someone forged their signature, changed the contents of the documents, or told the creator untruths that caused them to alter their estate plan. 
  • Revocation. Claiming the creator legally canceled or replaced the document before they died. Common forms of revocation include physically destroying the document, creating a new will or trust that expressly revokes the old one, or making a formal written revocation.

You can also contest trusts and wills based on how well the creator followed California law.

Grounds to Contest a Will in California

Apart from the overlapping challenge grounds, grounds to contest a will in California also focus on the strict legal standards surrounding how a person creates a legally valid will. To create a valid will, a testator must:

If the testator did not complete these steps, you may challenge a will for not being executed in line with the law.

Unique Considerations When You Challenge a Trust in California

Trusts can serve many different purposes, but they have four primary structures:

  • Living—created during the grantor’s life;
  • Testamentary—created after the grantor’s death;
  • Revocable—grantor can transfer trust property back to themself; and
  • Irrevocable—grantor does not have the right to transfer trust property back to themself.

Challenging a living, revocable trust, where the grantor may simply cancel the trust if challenged, works differently than less flexible trust types.

Who Can Contest a Will or Trust?

California law only allows those with something to lose or gain from the outcome to sue, which is called having standing. You may have standing to contest a trust or will if you are an interested person, like:

  • A named beneficiary in the current or a prior version of the document;
  • A legal heir who would inherit under California’s intestacy rules if the document were invalid; or
  • Others with a financial stake, such as a creditor still owed money or an omitted spouse entitled to a share by law.

Generally, you have standing if, in some possible legal circumstances, you might be entitled to share in the estate or trust.

How to Contest a Will or Contest a Trust in California

Contesting a will or trust in California involves a series of legal steps, including:

  • Consult an attorney. An experienced will and trust litigation attorney can assess whether you have legal grounds to challenge the will or trust and guide you through the next steps.
  • Gather preliminary evidence. Collect documents and information, like prior estate plans, emails, medical records, or witness names.
  • File a petition in court. To initiate the contest, you file formal legal paperwork identifying the document being challenged, your legal grounds for contesting it, and what you are asking the court to do.
  • Serve notice to interested parties. You must notify all potentially affected individuals about the challenge.
  • Continue building your case. After filing, both sides can use the discovery process to request documents, ask questions, and consult experts.
  • Attend mediation. Most disputes settle through mediation, where a neutral third party works with those involved to reach cooperative solutions, which can save time, reduce fees, and avoid the emotional strain of a trial.

If settlement fails, the case may go to trial, where a judge decides whether to uphold or invalidate the document.
