Maryland Will Requirements

Maryland will requirements live in Title 4 of the Estates and Trusts Article, and most people want one answer first: what makes a will valid here. The maker (the testator) must be at least 18 and legally competent to make a will. The document must be in writing, signed by the testator (or by another person for the testator, in the testator's physical presence and at the testator's direction), and attested and signed by two or more credible witnesses in the testator's physical presence. Maryland also allows electronic and remotely witnessed wills through a supervising attorney, and it accepts a handwritten (holographic) will only for a member of the armed services who signs outside the United States. (See Md. Code, Estates and Trusts §4-102 and §4-103.)

Use this page as a planning map, not as legal advice or a do-it-yourself signing kit. Maryland courts apply these statutes to the facts of each will, and one signing slip can put a will at risk. When real property, a blended family, or a possible dispute is in play, confirm your plan with a licensed Maryland attorney before you sign.

This guide pairs with the Maryland probate guide for what happens after death, and with Maryland intestate succession for who inherits when no valid will exists.

Who Can Make a Will in Maryland

Two capacity rules sit at the front of Maryland will requirements. Md. Code, Estates and Trusts §4-102 says any person may make a will if that person is 18 years of age or older and legally competent to make a will.

In plain terms:

• Age. The maker must be at least 18. A person younger than 18 cannot make a valid Maryland will.
• Legal competence. The maker must understand, in a general way, that he is making a will, the nature and extent of his property, and the people who would ordinarily receive it. A will signed by someone who lacks that understanding is open to challenge.

Competence is judged at the moment of signing, not before or after. A later illness does not undo a will that was validly made while the testator understood what he was doing.

How to Sign a Valid Will

For a typed or printed will (the kind most people use), Md. Code, Estates and Trusts §4-102 sets three linked requirements.

1. Writing and signature. The will must be in writing and signed by the testator. Another person may sign for the testator, but only in the testator's physical presence and at the testator's direction.
2. Two credible witnesses. The will must be attested and signed by two or more credible witnesses. A credible witness is one who is competent to testify about the signing.
3. Signed in the testator's presence. Those witnesses must sign in the testator's physical presence (or, for an electronic will, in the testator's electronic presence under the rules below).

The two-witness step is the part that trips up homemade wills. Both witnesses have to sign the will in the testator's presence, and a witness who signs later or in another room breaks the chain. Maryland does not spell out that the testator has to sign before the witnesses, and it does not require the witnesses to sign in front of each other, but the safe practice is to have the testator and both witnesses together in one sitting and sign in a single, unbroken session. Choose witnesses who take nothing under the will when you can, and keep them reachable in case a question comes up.

A short reassurance about notaries. Maryland does not require a plain paper will to be notarized to be valid. A notary comes into play only with the electronic and remotely witnessed will options described next. A will signed by the testator and two credible witnesses is valid with no notary.

Electronic and Remotely Witnessed Wills

Maryland modernized its will rules to allow electronic wills and remote witnessing. Under Md. Code, Estates and Trusts §4-102, a will may be signed and witnessed through electronic audio-visual means when a supervising attorney runs the signing and the people involved meet the statute's conditions. The testator must be in Maryland, the witnesses must reside in the United States, and the supervising attorney (a lawyer in good standing in Maryland) certifies the process.

Here is what makes this path different from a plain paper will:

• A supervising attorney is required. The remote and electronic options run through an attorney, not a do-it-yourself online form.
• A notary and sworn affidavits are built in. The attorney assembles a certified will that includes the testator's acknowledgment and the attesting witnesses' affidavits, notarized in the form the statute sets out. That notarized package is what makes the will self-proved.
• The certified will becomes the original. Once the supervising attorney certifies it, the certified will is treated as the original for probate.

If you are signing a routine will at a kitchen table with two witnesses in the room, you do not need any of this. The electronic and remote rules are an option, not a requirement.

Handwritten and Oral Wills

Most states let anyone make a fully handwritten (holographic) will. Maryland is stricter. Under Md. Code, Estates and Trusts §4-103, a will entirely in the testator's handwriting is valid without witnesses only when the testator is serving in the armed services of the United States and signs the will outside a state of the United States, the District of Columbia, or a United States territory. So a handwritten, unwitnessed will works for a deployed service member abroad, and for almost no one else.

Two limits ride along with that narrow exception:

• It expires. An armed-services holographic will becomes void one year after the testator is discharged from the service, unless the testator dies within that year or is not competent to make a will at the time of discharge.
• It is the exception, not a fallback. A civilian in Maryland cannot lean on a handwritten note as a will. If you are not a service member signing abroad, your will needs the writing, signature, and two-witness formalities above.

Maryland also gives no general path for an oral (spoken) will. Do not lean on a verbal statement of wishes as a substitute for a signed, witnessed document.

Proving a Maryland Will

A valid will still has to be proved before the Register of Wills after death. Maryland opens most estates through administrative probate, and in an uncontested administrative probate the attesting witnesses usually do not have to appear or testify. The Register admits the will based on the petition and the document itself.

Witness testimony tends to come up in two places: judicial probate, which the Register or an interested person can request, and a caveat, which is Maryland's name for a will challenge heard by the Orphans' Court. That is one reason a clean signing matters. If a challenge is filed, the people who watched the testator sign may be asked what they saw.

An attestation clause helps here. That is the short paragraph above the witness signatures stating that the testator signed in their presence and appeared competent. It is not required, but it records the facts while everyone remembers them. For the electronic and remote options above, the notarized affidavits do the same job in a stronger, self-proved form.

Witnesses Who Are Also Beneficiaries

A frequent worry is whether a will fails because a witness also inherits under it. In Maryland, a person who stands to inherit is not automatically barred from serving as a witness, and using one does not by itself void the will. Maryland has no statute that strips or reduces a witness-beneficiary's gift the way some states do. (Source: Md. Code, Estates and Trusts §4-102.)

Even with that leeway, a beneficiary-witness is a gift to anyone who later wants to challenge the will. It hands them an argument about undue influence or bias. The safe practice stays the same: use witnesses who take nothing under the will, and keep beneficiaries out of the witness line.

Depositing Your Will With the Register of Wills

Maryland lets you file your original will with the Register of Wills for safekeeping while you are alive. Under Md. Code, Estates and Trusts §4-202, the testator (or the testator's agent) may deposit the will, sealed in a wrapper marked with the testator's name and address, with the Register in the county where the testator lives. You pay a small fee and get a receipt.

While you are living, the deposited will can be handed back only to you or to someone you name in writing. After the Register learns of your death, the office opens the will and holds it for probate. Depositing the will is one way to make sure the signed original is not lost, which matters because Maryland probates the original document, not a copy.

Signing a Will Outside Maryland

A will signed while you are physically outside Maryland can still be valid here. Under Md. Code, Estates and Trusts §4-104, a will executed out of state holds up if it is in writing, signed by the testator (or by another person for the testator, in the testator's physical presence and at the testator's direction), and executed under any one of three sets of rules: Maryland's own §4-102 formalities, the law of the testator's home state, or the law of the place where the testator signed. So a will drafted correctly in another state generally travels to Maryland without a redo.

How a Maryland Will Is Revoked or Changed

A valid will can be undone, and Maryland spells out the ways in Md. Code, Estates and Trusts §4-105. A will cannot be revoked except by one of these methods:

• A later will. A newer, validly executed will revokes an earlier one, either by saying so or by leaving terms that cannot both stand.
• A physical act. Burning, canceling, tearing, or obliterating the will revokes it, whether the testator does it or directs someone else to do it in the testator's presence.
• Marriage plus a child. If the testator marries after signing a will and then has, adopts, or legitimates a child who survives the testator, every will made before that marriage is revoked.
• Divorce or annulment. An absolute divorce or an annulment after the will is signed revokes the provisions that relate to the former spouse, and only those provisions, unless the will or the decree says otherwise. The rest of the will stands.

The divorce rule catches many people off guard. Because a divorce cancels the gifts to an ex-spouse by operation of law, review your full plan after any divorce or new marriage. Your will, your beneficiary designations, and any trust may not follow the same rules, so update each one to match what you want.

What This Means for Your Plan

If you want a Maryland will that holds up, the cleanest version usually looks like this:

1. Confirm the testator is at least 18 and legally competent.
2. Put the will in writing and have the testator sign it.
3. Sign in front of two credible, ideally disinterested, witnesses, and have both witnesses sign in the testator's presence.
4. Add an attestation clause above the witness lines so the signing facts are recorded, or use the electronic or remote option with a supervising attorney if you want a notarized, self-proved will.
5. Store the original where your personal representative can find it, or deposit it with the Register of Wills, because Maryland probates the original.

A will is one piece of a broader Maryland estate plan. Many people pair it with documents that work during life and tools that keep assets out of probate. See the Maryland power of attorney guide and the Maryland advance directive guide for the lifetime documents, the Maryland guide to avoiding probate and the Maryland revocable living trust guide for probate-reduction tools, and the Maryland surviving spouse rights guide for the elective share a spouse can claim instead of taking under the will. When a signing formality is missed or a will is signed under pressure, these same rules become the basis for a caveat; see how to contest a Maryland will. For the bigger picture of how an estate moves through the Register of Wills and the Orphans' Court, start at the Maryland probate guide or the Maryland probate hub.

This guide is general information about Maryland wills. Confirm anything that affects your situation with your local Register of Wills or a licensed Maryland attorney before you sign or rely on a will.
