Yes, a lawyer can witness a will, including one they drafted, as long as the lawyer does not inherit anything under it. Because the attorney has no financial stake in the document, they count as a disinterested witness under any state’s rules, and it is routine in law offices for the drafting attorney or their staff to witness will signings. Whether they should is a different question, and the answer depends on how much you want to protect the will from a future contest.
Why a Lawyer Qualifies
Every state sets its own execution rules, but the core requirements are consistent. A witness must be a legal adult, typically 18, and mentally competent, meaning they can understand what they are watching and could describe it later in court if asked. The Uniform Probate Code, which has shaped the law in most states, requires at least two witnesses who sign the will within a reasonable time after watching the testator sign or hearing the testator confirm the signature.
Witnesses are the will’s first line of defense against fraud. Their signatures confirm the person signing is the testator, that the testator understands the document, and that no one is forcing or manipulating them. The drafting attorney meets every one of these criteria. They are an adult, they are competent, they are present, and unless the will leaves them property, they have no financial interest in its contents.
Being named as executor does not change this. Executors receive a fee for administering the estate, but that fee comes from the administration process, not from a gift in the will. The question that matters is always whether the lawyer inherits property under the will, never whether they play an administrative role afterward.
The Interested Witness Rules the Lawyer Has to Clear
An interested witness is someone who stands to inherit under the will they are witnessing. The concern is that a person who benefits has a reason to make sure the will gets validated, which could tempt them to overlook problems with the testator’s mental state or freedom from pressure. States handle interested witnesses three different ways:
- Under the Uniform Probate Code, an interested witness does not invalidate the will or any gift in it. The two-witness requirement is treated as protection enough.
- Many states use purging statutes. The will stays valid, but the interested witness’s gift is voided. If your neighbor is named to receive $10,000 and also signs as a witness, the neighbor loses that inheritance while the rest of the will is probated as written.
- Some purging statutes let an interested witness keep the lesser of their gift under the will or the amount they would have received under intestacy.
Purging-statute states usually contain a supernumerary exception: if enough disinterested witnesses also signed, the interested witness keeps the gift. This is one reason some lawyers arrange three witnesses instead of two.
None of this trips up the drafting lawyer, because they are not a beneficiary. It matters only if you were also thinking of asking a family member or friend named in the will to sign.
The Ethics Problem That Shows Up Later
Witnessing a will is fine at the moment of signing. The complication surfaces years later if someone contests the will and the same lawyer who drafted and witnessed it wants to defend it in litigation.
ABA Model Rule 3.7 prohibits a lawyer from acting as an advocate at a trial where the lawyer is likely to be a necessary witness. The rule contains three narrow exceptions: the testimony involves an uncontested issue, the testimony concerns the value of the lawyer’s own legal services, or disqualification would cause substantial hardship to the client.1American Bar Association. Rule 3.7: Lawyer as Witness A different lawyer from the same firm can still serve as the trial advocate, provided no separate conflict of interest exists under the general conflict rules.
The practical consequence: a solo practitioner who drafted and witnessed a will, and who later wants to defend it in a will contest, faces near-certain disqualification. The attorney’s testimony about the testator’s mental state, the circumstances of the signing, and the testator’s intentions is exactly the evidence that decides contests. Larger firms can work around it by having a different partner handle the litigation. For small practices, this is a real constraint worth thinking about before the attorney picks up the pen.
Undue Influence Optics
When the same lawyer both prepares and witnesses a will, unhappy family members have an easier time constructing an undue influence narrative. The argument writes itself: the attorney controlled the drafting process, was present at the signing, and had every opportunity to steer the testator’s decisions. The legal standard for proving undue influence is high, requiring a challenger to show the attorney actually manipulated the testator, not just that the opportunity existed. But the optics of the dual role give challengers something to work with that they would not have if an unrelated person witnessed the signing.
Attorney-Client Privilege Exposure
If the drafting attorney is called to testify in a will contest, the testimony can bleed into privileged territory. The lawyer may be asked about conversations with the testator, the reasons for specific bequests, or whether the testator seemed confused during consultations. Courts generally hold that privilege is not automatically waived just because the attorney testifies about the signing ceremony, but the line between what happened at the signing and what the client said in confidence can be thin. Opposing counsel will push that line as far as the judge allows.
Add a Self-Proving Affidavit
A self-proving affidavit is a sworn statement attached to the will, signed by the testator and the witnesses in front of a notary public. It eliminates the need for witnesses to appear in probate court to confirm the will is genuine, replacing live testimony with a notarized declaration that the signing followed all legal requirements.
Most states authorize self-proving affidavits, and the Uniform Probate Code provides a standard form. The affidavit typically states that the testator appeared to be of sound mind and was not under constraint at the time of signing. A will with a properly executed self-proving affidavit creates a presumption of validity that a challenger must overcome.
When a lawyer acts as a witness, the affidavit is especially valuable. If the will is never contested, it speeds up probate. If it is contested, the notarized affidavit provides independent corroboration of the signing ceremony beyond the attorney’s word. Notary fees are nominal, typically a few dollars to around $15 depending on the state.
The Safer Approach
The cleanest arrangement is to use two or three witnesses who have no connection to the will’s contents or its preparation. Office staff, a neighbor, or any competent adult who is not a beneficiary works. This removes any appearance of conflict and keeps the drafting attorney free to serve as litigation counsel if the will is later challenged.
If the attorney does serve as a witness, which is sometimes unavoidable in small towns or time-pressed situations, add a self-proving affidavit and make sure at least one other disinterested witness also signs. Contemporaneous file notes on the testator’s understanding of their assets, family relationships, and the effect of their bequests can be invaluable if anyone later questions capacity or freedom from influence.
