A probate lawsuit is a legal dispute that arises during the court-supervised process of administering a deceased person’s estate. Probate itself, validating a will, paying debts, and distributing assets, is not inherently adversarial. A “lawsuit” enters the picture when someone formally challenges the will, the executor, or how the estate is being handled.
This matters the moment a family member suspects the will doesn’t reflect a loved one’s true wishes, or an executor stops communicating, delays distributions, or appears to be helping themselves to estate funds. Probate court has specific tools for both situations: contesting a will’s validity, and holding a fiduciary accountable for mismanaging an estate.
- What it is: A legal challenge filed in probate court, either contesting a will’s validity or accusing an executor of mismanaging the estate.
- Who it applies to: Heirs, beneficiaries, and anyone with a financial interest in how a deceased person’s estate is distributed.
- When it matters: After a will surfaces with suspicious circumstances, or an executor withholds information, delays distributions, or misuses estate funds.
- Key exception: Only people who would financially benefit if the contest succeeds generally have standing to challenge a will.
- Practical takeaway: Deadlines to contest a will are short, often 30 days to two years depending on the state, and missing one usually ends the claim.

The Two Main Types of Probate Litigation
Probate disputes generally fall into two categories: contesting the validity of a will, and challenging how an executor or administrator is managing the estate. Each follows a different legal test and a different timeline.
| Dispute Type | What’s Being Challenged | Who Typically Files |
|---|---|---|
| Will contest | The validity of the will itself | Heirs or beneficiaries under a prior will |
| Breach of fiduciary duty | The executor’s or administrator’s conduct | Beneficiaries of the current estate |
Will Contests
What matters here is that a will contest doesn’t argue the distribution is unfair. It argues the document itself isn’t legally valid. Courts presume a will is valid, which means the person contesting carries the burden of proving otherwise.
Fiduciary Misconduct Claims
The pattern is familiar: an executor stops responding to questions, delays an inventory, or makes a transaction that benefits themselves at the estate’s expense. These claims accept that the will is valid but argue the person administering it is failing the legal duties that role requires.
Grounds for Contesting a Will
A will can only be contested on specific legal grounds, and disagreeing with how assets were divided is not one of them. Courts require concrete evidence the will itself is defective, not just unfair.
- Lack of testamentary capacity: the testator didn’t understand what they were signing
- Undue influence: someone used a position of trust to pressure the testator
- Fraud: the testator was deceived about the document or its contents
- Improper execution: the will wasn’t signed or witnessed as state law requires
- Revocation: a later, valid will replaced the one being offered for probate
Who Has Standing to Contest
This is the core principle: only someone who would receive more if the contest succeeds has standing to bring it. A person who would inherit less, or nothing at all, generally cannot challenge a will simply because they disagree with the testator’s choices.
Lack of Testamentary Capacity
The person contesting has to show the testator didn’t understand the nature of their property, who their natural heirs were, or what signing the document actually did, typically due to dementia, severe mental illness, or impairment at the exact moment of signing.
Undue Influence
Here is where it gets complicated. Undue influence requires more than a close relationship or even financial dependence on a caregiver. It requires showing that influence actually overpowered the testator’s free will, replacing their true wishes with someone else’s.
How Long You Have to Contest a Will
Every state sets a strict deadline to contest a will, ranging from roughly 30 days to two years depending on the state and when the clock starts. Missing it generally ends the right to challenge, regardless of how strong the underlying claim might be.
| Trigger Event | Typical Deadline Range |
|---|---|
| Will admitted to probate | 120 days to 2 years, depending on the state |
| Notice of administration received | Often 3 to 6 months from receipt |
| Discovery of a later will | Can extend or reopen the filing period |
Contesting Before Probate vs. After
A will can usually be contested before it’s admitted to probate by filing an objection ahead of the initial hearing, or after admission, within the state’s statutory window. Acting before admission generally avoids unwinding distributions that may have already started.
What Happens When a Fiduciary Breaches Their Duty
An executor or administrator who fails to act in the estate’s best interest can be removed, ordered to repay losses personally, or both. The fiduciary duty applies regardless of whether the executor is also a beneficiary.
A court order requiring a fiduciary to personally repay the estate for financial losses caused by their breach of duty, separate from removing them from the role entirely.
Common Fiduciary Breaches
- Misappropriating estate funds, including paying personal expenses from an estate account
- Self-dealing, such as selling estate property to themselves below market value
- Unreasonably delaying distributions to beneficiaries without a valid explanation
- Failing to provide an accounting or refusing to communicate with beneficiaries
- Mismanaging estate assets, such as letting property fall into disrepair or lapse on insurance
Remedies Courts Can Order
The practical implication is this: a beneficiary doesn’t have to choose between removing a bad executor and recovering what they took. Courts can do both, removing the fiduciary from the role while also surcharging them personally for the losses their misconduct caused.
Compelling an Accounting
Beneficiaries generally have the right to demand a formal accounting of how an executor has managed estate assets, and a court can compel one if the executor refuses. This is often the first real step toward uncovering a fiduciary breach.
No vague reassurance should satisfy a beneficiary who suspects something is wrong. A formal accounting lists every asset, every expense, and every distribution, giving beneficiaries and their attorneys the documentation needed to spot self-dealing or mismanagement that informal updates would never reveal.
What If There’s No Will at All
When someone dies without a valid will, known as dying intestate, state law determines who inherits, and disputes can still arise over who qualifies as an heir or who should administer the estate. Intestacy doesn’t eliminate probate litigation; it just changes what’s being fought over.
What matters here is that intestate succession follows a fixed legal order, typically starting with a spouse and children, then parents and siblings, regardless of what the deceased might have informally promised someone during their lifetime.
Common Misconceptions
Several persistent misconceptions cause families to either give up valid claims too early or pursue contests with no real chance of success. Understanding the actual legal bar changes how a dispute should be approached.
- Being unhappy with what you inherited is not, by itself, a valid reason to contest a will; courts require a specific legal defect, not just disappointment.
- A “no-contest clause” threatening disinheritance for challenging a will is not automatically enforceable in every state, and some states limit it significantly.
- An executor who is also a beneficiary is not automatically conflicted; that overlap is common and presumed to incentivize careful management, not abuse.
- Successful will contests are uncommon; courts presume a will is valid, and the burden of proving otherwise falls entirely on the person challenging it.
State Law Variations Worth Knowing
Deadlines, standing requirements, and how aggressively courts enforce no-contest clauses all vary significantly from state to state. The same set of facts can produce very different outcomes depending on where probate is filed.
California gives 120 days from a will’s admission to probate to file a contest. Texas allows up to two years, with some exceptions that can extend it further. Some states enforce no-contest clauses strictly, stripping an unsuccessful challenger of their entire inheritance, while others limit or refuse to enforce them when the contest was filed in good faith.
Always note this explicitly: probate is generally administered in the state and county where the deceased lived, which means the controlling deadlines and standards depend entirely on that jurisdiction, not where heirs happen to live now.

Frequently Asked Questions
Can I contest a will just because I think it’s unfair?
No. Disagreeing with how assets were divided is not a valid legal ground. You must show a specific defect, such as lack of capacity, undue influence, fraud, or improper execution.
Who has the legal right to contest a will?
Generally, only someone who would inherit more if the contest succeeds, such as an heir under a prior will or under intestate succession, has legal standing to challenge it.
How long do I have to contest a will?
Deadlines vary widely by state and trigger event, ranging from roughly 120 days to two years after the will is admitted to probate or after you receive notice of the proceeding.
Can I force an executor to show me a full accounting of the estate?
Beneficiaries generally have the right to demand one, and a probate court can compel an accounting if the executor refuses or provides an incomplete one.
What happens if an executor steals from the estate?
Courts can order a surcharge, requiring the executor to personally repay the estate for losses caused by their misconduct, separate from removing them from the role.
Will I lose my inheritance if I contest the will and lose?
Not automatically. Many states limit or refuse to enforce these clauses when a contest was filed in good faith and based on probable cause, though enforcement varies significantly.
What happens if someone dies without a will?
State law determines who inherits through a fixed order, typically starting with a spouse and children, but disputes can still arise over who qualifies as an heir or who should administer the estate.
Is it a conflict of interest if the executor is also a beneficiary?
No. An executor who is also a beneficiary is common and not automatically a conflict of interest; the law presumes it incentivizes careful management of the estate.
