1. First Identify What Kind of Probate Dispute Exists
Probate disputes may arise from the same estate but involve different legal issues. A will contest challenges whether the testamentary document should control. An administration dispute focuses on what happens after death, including management, accounting, or distribution of estate assets. Both can arise within the broader probate and estate administration process.
A Will Contest Challenges Whether the Will Should Control
A will contest may involve improper execution, lack of testamentary capacity, fraud, duress, menace, or undue influence. California Probate Code § 6100.5 governs testamentary capacity, while § 6104 provides that execution or revocation procured by duress, menace, fraud, or undue influence is ineffective to that extent.
The evidence should match the challenge. Medical records may matter in a capacity dispute, while communications, drafting records, witness testimony, or evidence surrounding changes to a last will and testament may matter more in an undue-influence or fraud claim.

Administration Disputes Focus on Conduct after Death
Not every probate dispute attacks the will. Beneficiaries may instead challenge an accounting, property sale, distribution decision, or the personal representative’s handling of estate assets.
That distinction matters because the requested relief is different. A beneficiary seeking information or challenging estate management is not necessarily asking the probate court to invalidate the will.
2. Standing and Timing Can Determine Whether a Challenge Proceeds
A strong claim can still face procedural problems if the person challenging the estate lacks the required interest or acts after an applicable deadline. California probate law therefore requires attention to both the challenger’s relationship to the estate and the stage of the proceeding.
The Challenger Must Have an Interest in the Estate
Probate Code § 48 defines an “interested person” to include heirs, devisees, children, spouses, creditors, beneficiaries, certain persons with property rights or claims affected by the proceeding, persons with priority for appointment, and fiduciaries representing interested persons.
The definition can vary with the proceeding. Being related to the decedent does not automatically answer whether a person has standing to pursue every type of probate dispute.
The Procedural Stage Changes the Form of the Contest
Before admission of a will, a contestant may object to probate under California’s will-contest procedures. Probate Code § 8250 addresses the objection, summons, and service process once that contest begins.
After a will has already been admitted, Probate Code § 8270 generally permits an eligible interested person to petition to revoke probate within 120 days, subject to statutory exclusions and exceptions. The admission date therefore matters more than waiting to see whether a later distribution creates a dispute.
3. Evidence and Estate Administration Shape the Case
Probate litigation usually depends on documents and conduct rather than family disagreement alone. The will, prior estate planning documents, medical records, financial records, accountings, correspondence, and witness testimony may each answer a different question.
Evidence Should Match the Legal Theory
A capacity challenge focuses on the decedent’s mental condition when the will was made. An undue-influence or fraud claim may depend more heavily on relationships, communications, changes in the estate plan, and the circumstances surrounding execution.
An administration dispute calls for a different record. Accountings, transaction documents, notices, property records, and communications from the personal representative may be more important than evidence about how the will was signed.
Disagreement with an Executor Is Not Automatically Misconduct
Beneficiaries may disagree with a personal representative’s decisions without establishing grounds for removal.
Probate Code § 8502 permits removal for specified reasons, including waste or mismanagement of estate property, fraud on the estate, inability to perform the role, wrongful neglect, or when removal is otherwise necessary to protect the estate or interested persons.
The question is therefore not whether beneficiaries dislike a decision, but whether the representative’s conduct fits a recognized basis for probate court intervention.
4. Probate Disputes May Be Settled or Litigated
A contested estate does not always have to end in trial. Negotiation or mediation may resolve disputes over distribution, property sales, accountings, or other issues the parties have authority to settle. Some California superior courts also operate probate mediation programs, although procedures differ by county.
Mediation Can Address Practical Estate Problems
A mediator does not decide who wins. The parties retain control over whether they reach an agreement.
That flexibility may help when a dispute involves several connected issues, such as who receives a particular asset, whether property should be sold, or how beneficiaries will resolve competing claims. Cases involving both probate and nonprobate arrangements may also overlap with broader trusts and estates issues.
Court Proceedings Remain Available When Agreement Fails
Some disputes require a judicial ruling because the parties cannot agree or because the requested relief depends on court action. A probate judge may need to decide questions involving will validity, removal of a personal representative, or other contested matters.
Choosing between settlement efforts and litigation therefore depends on the legal issue, the available evidence, the relief requested, and whether a workable agreement is possible.
5. Frequently Asked Questions
How Long Do I Have to Contest a Will After It Is Admitted to Probate?
California Probate Code § 8270 generally gives an eligible interested person 120 days after admission of the will to petition to revoke probate. The statute excludes certain people who already participated in, or had timely actual notice of, an earlier will contest and contains a separate rule for certain minors or incompetent persons without a guardian or conservator.
Because the period runs from admission of the will, the court record should be checked promptly rather than waiting for distribution.
Can an Executor Be Removed for Mishandling an Estate?
Potentially. Probate Code § 8502 allows a court to remove a personal representative for specified grounds such as waste or mismanagement, fraud on the estate, incapacity to perform the role, wrongful neglect, or when removal is otherwise necessary to protect the estate or interested persons.
A disagreement over judgment or strategy alone does not establish one of those grounds. The relevant facts are what the representative did, what duties applied, and how that conduct affected the estate.
6. When to Speak with a Probate Dispute Lawyer
A contested probate matter may involve will validity, standing, a filing deadline, disputed administration, or disagreement over distribution. A probate lawyer can review the will, probate filings, estate records, communications, and current stage of administration to identify which issue requires action.
Early review can matter when a will has already been admitted, estate property is being sold or distributed, or family members dispute the personal representative’s conduct.
