Contesting a Will in Maryland: Grounds, Timeline, and Process

Contesting a will in Maryland is difficult by design. The courts presume a properly executed will reflects the testator's wishes, and the burden falls entirely on the challenger to prove otherwise. Most will contests fail.

But when the grounds are legitimate — undue influence by a caretaker, a testator who lacked mental capacity, a forged signature — the process exists to protect families from fraudulent or coerced documents.

Who Can Contest

Not everyone has standing to challenge a will. In Maryland, you must be an "interested person" — someone with a financial stake in the outcome:

• Heirs at law — people who would inherit under intestacy if the will were invalidated
• Beneficiaries named in a prior will — people who stood to inherit under an earlier version
• Creditors of the estate — with a valid claim against the decedent

A friend, neighbor, or concerned community member who believes the will is unfair cannot bring a challenge unless they have a direct financial interest.

Legal Grounds for Contesting

Maryland recognizes four primary grounds:

Lack of testamentary capacity. The testator didn't understand what they were doing when they signed the will. In Maryland, testamentary capacity requires understanding the nature and extent of your property, who your natural beneficiaries are, and what the will does. Dementia, Alzheimer's, or severe mental illness at the time of signing can support this claim — but the standard is low. A person can have early-stage dementia and still possess testamentary capacity during a lucid interval.

Undue influence. Someone exerted pressure that overcame the testator's free will. Maryland courts look for a confidential relationship (caretaker, attorney, family member with control), opportunity to exert influence, and a will that benefits the influencer in a way that doesn't match the testator's prior expressed intentions. A child who moved in to care for an aging parent and was then named sole beneficiary — displacing siblings who had equal shares in a prior will — raises the classic undue influence pattern.

Fraud. The testator was deceived about the will's contents or about facts that influenced their decisions. This includes someone telling the testator a family member has died or abandoned them when that isn't true, or presenting a document for signature while misrepresenting what it says.

Improper execution. The will doesn't meet Maryland's formal requirements: it must be in writing, signed by the testator (or by someone at their direction and in their presence), and witnessed by two credible witnesses. A will with only one witness, a will the testator didn't actually sign, or a will with witnesses who didn't watch the signing (or acknowledge it) can be challenged on execution grounds. This is the most straightforward ground because it's based on verifiable facts, not contested interpretations.

The Timeline

The window for contesting is narrow:

Within six months of the personal representative's appointment — for any interested person who received proper notice. The Register of Wills sends the List of Interested Persons (Form 1104) to all heirs and named beneficiaries within 20 days of the personal representative's appointment.

Missing this deadline generally forecloses the challenge. Maryland courts are strict about the statute of limitations on will contests.

The Process

A will contest in Maryland typically proceeds through the Orphans' Court, which has exclusive jurisdiction over probate matters in each county. The basic steps:

1. File a caveat with the Register of Wills in the county where the will was admitted to probate
2. The Register transmits the caveat to the Orphans' Court
3. The court schedules a hearing where both sides present evidence
4. Either party can request transfer to the Circuit Court for a jury trial

Evidence in will contests typically includes medical records (for capacity challenges), testimony from the witnesses who signed the will, testimony from family members about the testator's relationships and expressed intentions, and financial records showing who benefited from changes to the will.

No-Contest Clauses

Some Maryland wills include an "in terrorem" or no-contest clause — a provision that disinherits anyone who challenges the will. Maryland courts generally enforce these clauses, meaning a failed challenge can cost you whatever you were set to inherit.

However, there's an exception: if the contestant has probable cause for the challenge (a genuine, good-faith belief supported by evidence), the no-contest clause may not be enforced. This prevents testators from using no-contest clauses to shield fraudulent or unduly influenced wills.

Preventing Will Contests

The best defense against a will contest is prevention during the planning process:

• Include a self-proving affidavit — eliminates execution challenges
• Have a physician document capacity at the time of signing, especially for elderly testators
• Use an independent attorney — not one chosen by a beneficiary
• Avoid sudden changes to long-standing plans without documenting the reasoning
• Communicate your intentions to family members (the surprise is often what triggers the challenge)

The Maryland Estate Planning Kit includes will execution checklists that address each of the four grounds for contest — ensuring proper witnesses, capacity documentation, and execution procedures that make a challenge much harder to sustain.
