Contest a Will in Maryland: At a Glance
Here are the Maryland facts that decide whether you can contest a will in Maryland:
| Deadline to contest | 6 months. A verified petition to caveat may be filed at any time before the expiration of 6 months following the first appointment of a personal representative under a will, regardless of whether a petition for probate has been filed, and even if there is a subsequent judicial probate or a subsequent appointment of a personal representative — Md. Code, Estates & Trusts § 5-207(a). A caveat may also be filed BEFORE the will is offered for probate. If a different will is later offered for probate, § 5-207 provides a separate, shorter window to caveat that later-offered will (exact number of months UNVERIFIED — confirm the current text of § 5-207 with the Register of Wills or a licensed Maryland attorney). |
| What starts the clock | The first appointment of a personal representative under a will (not the date of death, not the date of notice to heirs, and not the date the will is admitted to probate) — Md. Code, Estates & Trusts § 5-207(a). Because the clock runs from that first appointment, the 6 months is not restarted by a later judicial probate or a later appointment of a different personal representative. |
| Who can contest | An “interested person” as defined in Md. Code, Estates & Trusts § 1-101(i) — generally the heirs at law who would inherit under Maryland intestacy if the will were set aside, and legatees named in any document purporting to be the decedent’s will or codicil (including a prior will). § 1-101(i) expressly provides that a person who timely files a petition to caveat under § 5-207 is an “interested person,” and ceases to be one once the caveat proceeding is disposed of. Md. Rule 6-431 identifies heirs of the decedent and legatees under any purported will or codicil as those who may file. Ordinary estate creditors do not have standing to caveat in Maryland; they pursue claims under Title 8 instead. |
| No-contest clause | YES, with a probable-cause exception. Md. Code, Estates & Trusts § 4-413: a provision in a will purporting to penalize an interested person for contesting the will or instituting other proceedings relating to the estate is VOID if probable cause exists for instituting the proceedings. So a Maryland no-contest clause is enforceable only where the contestant lacked probable cause. |
| What the filing is called | A “petition to caveat” (the caveat proceeding), filed as a verified petition with the Register of Wills for the county (or Baltimore City) where the estate is or would be administered — Md. Code, Estates & Trusts § 5-207; Md. Rule 6-431. A petition filed before a petition for probate, or after administrative probate, operates as a request for judicial probate; if filed after judicial probate, the matter is reopened and heard anew as if only administrative probate had occurred. |
| Court | The Orphans’ Court for the Maryland county (or Baltimore City) where the estate is administered, with the Register of Wills as the filing office. In Montgomery County and Harford County there is no separate Orphans’ Court — Circuit Court judges sit as the Orphans’ Court (Md. Const. Art. IV, § 20). Contested issues of fact may be transmitted to the Circuit Court. |
| Jury trial | YES — indirectly. The Orphans’ Court itself does not empanel juries. At the request of an interested person made within the time set by the court, an issue of fact may be determined by a court of law; when the request is made before the Orphans’ Court has decided the issue, the court SHALL transmit the issue to a court of law (the Circuit Court), where a jury may decide it — Md. Code, Estates & Trusts § 2-105(b); see also § 5-404 and Md. Rule 6-434 (petition to transmit issues). Issues such as fraud, undue influence, and lack of testamentary capacity are routinely certified to Circuit Court for jury trial. |
| Typical cost | UNVERIFIED. No official Maryland court or Register of Wills source publishes a typical dollar range for a contested caveat case. Costs commonly include attorney fees, court costs, and expert witness fees; caveators who are heirs generally pay their own counsel out of pocket while the personal representative may defend the will using estate funds. Check with your state’s court or a licensed attorney for a case-specific estimate. |
The Deadline to Contest a Will in Maryland
The window is short in some states and long in others, and it is measured from a specific event rather than from the day you learned about the will. That is why the first thing to find out is the date the will was admitted and whether you received formal notice. If the deadline has not run, everything else on this page is available to you.
If it has, the remaining options are narrow and usually involve proving you never got the notice the law required.
Grounds to Contest a Will in Maryland
Lack of testamentary capacity at the time of execution; undue influence; fraud; duress; improper/defective execution (Maryland requires the will be in writing, signed by the testator, and attested and signed by two credible witnesses in the testator’s presence — Md. Code, Estates & Trusts § 4-102); forgery; and revocation (a later will, codicil, or physical act of revocation under Md. Code, Estates & Trusts § 4-105).
Who has to prove what: The contestant (caveator) generally carries the burden of proving the invalidating ground. For testamentary undue influence the burden of proof rests on the party attacking the will.
Where a confidential relationship between the testator and a beneficiary is established, Maryland shifts the burden to the beneficiary/proponent; in the analogous inter vivos gift context, proof of a confidential relationship creates a presumption against validity and the donee must establish by clear and convincing evidence that there was no abuse of the confidence. The proponent bears the burden of showing due execution.
Standards vary by ground and by whether a presumption applies — confirm the applicable standard with a licensed Maryland attorney.
Who Can Contest a Will in Maryland
An “interested person” as defined in Md.
Code, Estates & Trusts § 1-101(i) — generally the heirs at law who would inherit under Maryland intestacy if the will were set aside,
and legatees named in any document purporting to be the decedent’s will or codicil (including a prior will). § 1-101(i) expressly provides that a person who timely files a petition to caveat under § 5-207 is an “interested person,” and ceases to be one once the caveat proceeding is disposed of.
Md. Rule 6-431 identifies heirs of the decedent and legatees under any purported will or codicil as those who may file. Ordinary estate creditors do not have standing to caveat in Maryland; they pursue claims under Title 8 instead. Being unhappy with the will is not standing; losing something because of it is.
Check the earlier will and the intestate rules for Maryland before filing, because they decide whether you are an interested person.
No-Contest Clauses in Maryland
YES, with a probable-cause exception. Md. Code, Estates & Trusts § 4-413: a provision in a will purporting to penalize an interested person for contesting the will or instituting other proceedings relating to the estate is VOID if probable cause exists for instituting the proceedings. So a Maryland no-contest clause is enforceable only where the contestant lacked probable cause.
The Steps to Contest a Will in Maryland
Step one is the deadline check above. Step two is evidence: the medical records around the signing date, the names of the witnesses, the drafting lawyer’s file, and the financial records that show who benefited.
Step three is the filing — A “petition to caveat” (the caveat proceeding), filed as a verified petition with the Register of Wills for the county (or Baltimore City) where the estate is or would be administered — Md. Code, Estates & Trusts § 5-207; Md. Rule 6-431.
A petition filed before a petition for probate, or after administrative probate, operates as a request for judicial probate; if filed after judicial probate, the matter is reopened and heard anew as if only administrative probate had occurred.. Step four is discovery and, in most cases, a settlement conference; the small minority that reach trial are decided by a jury if requested.

Settling Instead of Fighting
YES — caveat disputes may be resolved by agreement among the interested persons, and mediation/ADR is available once contested issues are transmitted to the Circuit Court under the Maryland Rules Title 17 ADR provisions (Md. Rule 17-202 et seq.). Many Maryland caveat matters settle before trial.
A specific Maryland statute codifying “family settlement agreements” was not verified in this research; any settlement affecting estate distribution should be presented to the Orphans’ Court or Register of Wills for approval — check with your state’s court or a licensed attorney.
Other Maryland rules: (1) Maryland has NO ante-mortem/pre-death will validation procedure — a will cannot be judicially validated during the testator’s lifetime. (2) The caveat clock runs from the first appointment of a personal representative, NOT from admission of the will to probate or from notice to heirs — an unusual trigger that can start before many heirs learn of the estate.
(3) A petition to caveat may be filed BEFORE the will is offered for probate. (4) Maryland uses a two-track probate system (administrative probate before the Register of Wills; judicial probate before the Orphans’ Court), and a caveat converts or reopens the matter into a judicial proceeding — Md. Code, Estates & Trusts § 5-207.
(5) Maryland is one of the few states with a separate constitutional Orphans’ Court, except Montgomery and Harford Counties, where Circuit Court judges serve as the Orphans’ Court (Md. Const. Art. IV, § 20). (6) Fact issues can be moved out of the Orphans’ Court to a Circuit Court jury under § 2-105(b).
(7) Maryland requires two credible attesting witnesses under § 4-102; whether Maryland recognizes a self-proving affidavit that creates a presumption of due execution was not verified in this research.
The Evidence That Wins or Loses a Will Contest
Capacity cases turn on the weeks around the signing: the medical chart, prescriptions, a dementia diagnosis, and what the drafting lawyer and the witnesses saw that day. A will signed in a lawyer’s office with two disinterested witnesses and a self-proving affidavit is hard to attack; a will signed at a kitchen table with the main beneficiary present is not.
Undue influence cases turn on the relationship — who drove the parent to the appointment, who chose the lawyer, who was in the room, and whether the new will departed sharply from earlier ones and from what the parent said to other people.
Improper execution is the narrowest ground and the cleanest: Maryland sets exact witness and signature rules, and a will that misses them fails regardless of what the signer intended. Before you contest a will in Maryland, gather the prior wills, the medical releases, and the names of everyone at the signing.
Most of that evidence has to be requested formally once the case is filed, and the deadline does not wait for it.
What to Expect When You Contest a Will in Maryland
A will contest is a lawsuit about the document, not about fairness. When you contest a will in Maryland, the court asks whether the person who signed it had capacity, signed it freely, and signed it correctly. It does not ask whether the split was reasonable. That is why the strongest cases rest on medical records and witness accounts from the weeks around the signing.
Most families who contest a will in Maryland settle. Courts encourage it, many states have family settlement rules that let the heirs agree to a different division, and a settlement avoids the cost and delay of trial. The deadline, the grounds, and the no-contest clause above are the three facts that set your bargaining position before any of that begins.
