Deadline to Contest a Will in California

John was devastated. His mother had recently passed, and he’d just discovered a codicil amending her will – removing him as a beneficiary entirely. He immediately wanted to challenge it, convinced his new caregiver had manipulated his frail mother in her final weeks. But when he contacted an attorney, he was stunned to learn he might already be too late. The window to contest a will in California is shockingly short, and missing it can mean accepting a fate you never would have agreed to, potentially costing him tens of thousands of dollars.

As an estate planning attorney and CPA with over 35 years of experience in Corona, California, I’ve seen countless situations like John’s. Families discover irregularities in a will or trust after probate has already begun, only to find their legal options severely limited by strict time constraints. This isn’t about fairness; it’s about legal procedure and the finality of estate settlements.

What is the Time Limit to Challenge a Will?

In California, the primary deadline revolves around the admission of the will to probate. Once the will is admitted to probate, interested parties have a strict 120-day window to file a petition to revoke probate. If you miss this deadline, the will is generally locked in stone, even if it was forged or signed under duress. This 120-day clock starts running from the date the court officially admits the will. Don’t assume you have a year, or even six months. It’s 120 days, no exceptions.

What if I Didn’t Know About the Will Right Away?

This is a common question. Often, family members are unaware of changes to an estate plan until after someone has passed away. However, California law doesn’t offer much leeway for delayed discovery. While you can petition the court for “relief from default” if you can demonstrate you genuinely didn’t know about the will and couldn’t reasonably have discovered it, proving this is difficult. The court will want to see evidence you acted diligently once you did become aware.

Can I Contest a Will Before Probate?

Yes, in limited circumstances. If you suspect the will is invalid, you can file a petition before probate begins, challenging its authenticity or the testator’s mental capacity. This is often more complex, requiring a deeper investigation upfront. However, it’s also strategically advantageous, as you’re not fighting against a court-approved document. Keep in mind, even pre-probate challenges can be subject to deadlines if other parties move to formally begin the probate process.

What Types of Challenges Are Possible?

• Forgery or Fraud: This involves proving the signature on the will is not genuine (execution fraud) or that the testator was tricked into signing it (inducement fraud). Proving a signature is fake often requires a forensic handwriting expert, whereas proving fraud in the inducement requires evidence that the testator relied on a lie (e.g., ‘your son is stealing from you’) to change their estate plan.
• Mental Capacity: California uses a relatively low threshold for capacity. A person is considered of ‘sound mind’ unless they lacked the ability to understand the nature of the testamentary act, the nature of their property, or their relationship to living family members (or suffered from a specific delusion). Probate Code § 6100.5 defines this standard.
• Undue Influence: This occurs when someone exerts control over the testator, overriding their free will. Probate Code § 21380 presumes undue influence if a gift is made to a care custodian of a dependent adult, shifting the burden of proof to the caregiver.
• Lack of Standing: You cannot contest a will just because you think it’s unfair. You must be an ‘interested person’—meaning you would financially benefit if the current will is overturned (e.g., a child disinherited by a new will, or a beneficiary named in a previous version). Probate Code § 48 outlines who qualifies.

As a CPA as well as an attorney, I can uniquely assist with these challenges. The step-up in basis rules, capital gains implications, and property valuation are all critical components of a successful probate contest. A nuanced understanding of both the legal and tax aspects is paramount.

Don’t gamble with your inheritance. If you suspect a will is invalid, act immediately. Waiting even a few weeks can forfeit your rights.

What failures trigger contested proceedings and court intervention in California probate administration?

California probate is designed to provide court-supervised transfer of property, yet cases often break down when authority is unclear, required steps are missed, or disputes arise over assets, notice, and fiduciary conduct. When the process is misunderstood, families can face avoidable delay, escalating conflict, and increased exposure to creditor issues, hearings, or litigation before the estate can close.

Ultimately, the difference between a routine distribution and a protracted legal battle often comes down to preparation. By anticipating the demands of the Probate Code and addressing potential friction points with beneficiaries and creditors upfront, fiduciaries can navigate the system with greater confidence and lower liability.

Verified Authority on California Will Contests

• The 120-Day Statute of Limitations: California Probate Code § 8270
  Time is the enemy in a will contest. Under Section 8270, an interested person may petition the court to revoke the probate of a will, but this petition MUST be filed within 120 days after the will is admitted. Missing this deadline is usually fatal to the case.
• Mental Competency Standard: California Probate Code § 6100.5 (Unsound Mind)
  This statute defines exactly what “mental incompetency” means in probate. It is not just general forgetfulness; the contestant must prove the deceased did not understand the nature of the testamentary act, could not recollect their property, or was suffering from a specific hallucination or delusion that dictated the will’s terms.
• Presumption of Undue Influence (Caregivers): California Probate Code § 21380
  To protect vulnerable seniors, California law automatically presumes undue influence if a will leaves assets to a paid care custodian or the lawyer who drafted the instrument. This shifts the heavy burden of proof onto the accused to prove their innocence.
• No-Contest Clause Enforceability: California Probate Code § 21311
  Many wills contain threats to disinherit anyone who challenges them. This statute limits the power of those clauses. A beneficiary cannot be penalized for a contest if the court finds they had “probable cause” to file the lawsuit.
• Standing to Contest: California Probate Code § 48 (Interested Person)
  Not everyone can sue. To contest a will, you must qualify as an “interested person”—typically an heir who would inherit under intestate succession (if there were no will) or a beneficiary named in a prior valid will.
• Financial Elder Abuse Remedies: California Probate Code § 859 (Double Damages)
  Will contests often overlap with elder abuse claims. If the court finds that a person used undue influence, fraud, or bad faith to take assets (or change a will) to the detriment of the estate, they can be liable for twice the value of the property taken, plus attorney fees.
