Discovering that a loved one’s final wishes were manipulated, forged, or written when they weren’t in a clear state of mind is devastating. When an unfair or legally flawed will is submitted to a Nevada probate court, you have the right to challenge it.
However, contesting a will in Nevada is not as simple as showing up to court and expressing your frustration. The state has incredibly strict deadlines, highly specific legal requirements, and harsh penalties for frivolous lawsuits.
If you are considering challenging a will in Clark County or anywhere across Nevada, here is exactly what you need to know about the process, the legal grounds required, and the strict timelines you must meet.
Who Has the “Standing” to Contest a Will in Nevada?
You cannot contest a will simply because you are unhappy with your inheritance or because a family member received a larger share. To file a formal challenge, you must have legal standing.
Under Nevada law, only an “interested person” has standing. This typically includes:
- Legal Heirs: Family members who would automatically inherit property under Nevada’s “intestacy laws” if no will existed (such as a spouse, children, or siblings).
- Named Beneficiaries: Anyone named in the current will, or named in a previous version of the will who was cut out or had their share reduced in the newer version.
- Creditors: Individuals or entities to whom the deceased owed money.
What Are Legal Grounds to Challenge a Will in Nevada?
To successfully contest a will, your petition must prove that the document is legally invalid based on specific statutory grounds. Nevada probate courts presume a signed will is valid until proven otherwise. The most common legal grounds include:
1. Lack of Testamentary Capacity
You must prove that at the exact moment the deceased signed the will, they lacked the mental capacity to understand what they were doing. This generally means demonstrating they did not understand the value or extent of their property, who their natural heirs were, or the practical effect of the document they were signing (often due to advanced dementia, Alzheimer’s, or severe medical sedation).
2. Undue Influence
This occurs when someone exerts extreme pressure, coercion, or manipulation over the deceased, overriding their free will. In Nevada, if a vulnerable person suddenly leaves their entire estate to a neighbor, a new romantic partner, or a live-in caretaker while completely cutting out their family, the court looks closely at potential undue influence.
3. Fraud or Forgery
If the signature on the will is fake, or if the deceased was tricked into signing the document (for example, being told they were signing a power of attorney when it was actually a will), the document is void due to fraud.
4. Improper Execution
Nevada has strict rules for how a will must be executed. Except for holographic (handwritten) wills, a valid Nevada will must be in writing, signed by the testator (or by someone in their presence and by their direction), and witnessed by at least two disinterested witnesses who sign the document in the testator’s presence. If it lacks these signatures, it can be thrown out.
The Nevada Will Contest Timeline
The probate process is designed to move quickly so that an estate can be settled and distributed.
- Phase 1: Discover Valid Legal Grounds
Work with an estate litigation attorney to review the will, medical records, and witness statements to establish strong, evidence-backed statutory grounds. - Phase 2: File the Petition Within 3 Months
Once a will is formally admitted to probate, NRS 137.080 dictates you have a maximum of three (3) months to file a formal petition contesting its validity. If you miss this 90-day window, you forfeit your right to challenge it. - Phase 3: Court Issues Citations
Upon receiving your petition, the probate court will issue citations to all personal representatives, beneficiaries, and interested parties named in the will, alerting them to your lawsuit. - Phase 4: The 30-Day Response Window
Once served with the citation, the parties defending the will have exactly 30 days to file a formal response (pleading) with the court. - Phase 5: The Discovery & Litigation Phase
Both sides enter the “discovery” period. Attorneys will subpoena medical records, order forensic handwriting analysis, depose witnesses, and gather evidence for trial. - Phase 6: Court Ruling or Settlement
If a settlement cannot be reached through mediation, a probate judge will hear the evidence at trial. If the judge rules the will is invalid, it is revoked, and the court will revert to a previous valid will or distribute assets via state law.
Beware of Nevada’s Strict “No-Contest Clauses”
Many modern wills contain a No-Contest Clause (also known as an in terrorem clause). This clause explicitly states that if a beneficiary challenges the validity of the will and loses, their inheritance is completely wiped out.
Crucial Nevada Law Update: Under Nevada Revised Statute (NRS) 137.005, Nevada courts enforce no-contest clauses to the greatest extent possible.
However, Nevada law does provide a vital safety net. Your share will not be eliminated if the court determines that you brought the legal action in good faith and with probable cause. Probable cause means that a reasonable, properly informed person looking at the facts would conclude that the will was genuinely invalid.
Because the stakes are so high—risking total disinheritance if you lose—you should never file a will contest without a lawyer evaluating your evidence first.
