Most wills do not have to be notarized to be legally valid, but several other estate planning documents do. Notarization requirements for wills and estate documents vary by the type of document: a will needs witnesses in nearly every state, while deeds, powers of attorney, trust certificates, and transfer-on-death deeds generally need a notary’s seal before anyone will honor them. The self-proving affidavit that attaches to a will is the piece most people are actually thinking of when they ask whether a will needs to be notarized.
Which Documents Need a Notary and Which Don’t
A properly witnessed will is valid in every state without a notary’s seal. The standard requirement is that the testator signs in front of two competent witnesses who also sign. About half the states additionally recognize holographic wills — handwritten documents that don’t need witnesses or notarization at all, as long as the signature and key provisions are in the testator’s handwriting. Holographic wills carry more risk of challenge, but they are legally valid where permitted.
The documents that genuinely require notarization are the ones that interact with third parties or public records:
- Deeds transferring real property into a trust. County recorder offices will reject an unnotarized deed, leaving the property outside the trust.
- Financial powers of attorney. Banks and investment firms rely on the notary’s seal as proof the signature is genuine before honoring an agent’s authority.
- Transfer-on-death deeds. These must be notarized and recorded with the county before the owner’s death to take effect, and some states impose a recording deadline that voids the deed if missed.
- Certificates of trust. Financial institutions typically refuse to open accounts or transfer funds without a notarized certificate.
Revocable and irrevocable living trusts don’t always need notarization themselves, but the deeds that move real property into the trust do. Without recording, the home stays in your name personally, which defeats the probate-avoidance purpose of the trust.
Healthcare directives sit in the middle. Most states accept either notarization or two witness signatures. Notarization is generally accepted more smoothly across state lines and by hospital legal departments that may not know the witnessing rules of the state where the document was signed.

What a Self-Proving Affidavit Does
A self-proving affidavit is a separate attachment to the will that eliminates the need for witnesses to appear in court during probate. Without one, the executor might have to track down witnesses years after the signing. If those witnesses have moved, become incapacitated, or died, proving the will was properly executed becomes expensive and slow.
Under the model most states adopted through the Uniform Probate Code, the testator and both witnesses sign sworn statements before a notary, confirming that the testator signed the will voluntarily, appeared to be of sound mind, and was at least 18 years old. The notary then certifies all three signatures under official seal. The notary is certifying both the testator’s and the witnesses’ signatures, not just the witnesses’.
The affidavit can be completed at the same sitting as the will itself, which is the approach most estate planning attorneys take. Some states allow it to be added later, but handling everything in one appointment avoids reuniting everyone. Skipping the affidavit doesn’t invalidate the will. It just means the court may need the witnesses to appear later and confirm they watched you sign.
What to Bring and How to Prepare
Bring government-issued photo identification. A driver’s license or U.S. passport works in every state. Military IDs and permanent resident cards are also accepted. The notary will compare your physical appearance to the photo, verify your signature, and record the identification details in their journal.
Fill in every blank on the document — names, dates, addresses — but leave every signature line empty. If you sign before the notary is present, they’ll refuse to proceed, and you’ll need fresh copies. This trips up more people than you’d expect, especially when documents arrive from an attorney’s office and the instinct is to sign immediately.
If witnesses are required, choose people over 18 who have no financial stake in the outcome. A neighbor, coworker, or friend works well. Anyone named as a beneficiary, executor, or trustee in the document is a poor choice and can create grounds for a legal challenge. Line up witnesses in advance so the appointment doesn’t stall.
Expect the notary to ask whether you understand what you’re signing and whether anyone is pressuring you. Questions like “Can you tell me what this document does?” and “Are you signing this of your own free will?” are not formalities. A notary who suspects confusion or coercion must refuse to proceed. If a family member or caregiver tries to answer on your behalf, a careful notary will ask to speak with you privately.
Who Shouldn’t Notarize Your Documents
A notary is supposed to be a disinterested witness. When the notary has a personal stake in the document, the entire notarization can be challenged or voided. This comes up most often in family estate planning, where a relative who happens to be a notary offers to handle the signing.
The core rule is simple: a notary should never notarize a document in which they are named or from which they would benefit. If the notary is listed as a beneficiary, executor, trustee, or agent in the document, they are disqualified. Many states have statutes explicitly barring notarization by someone with a direct beneficial interest, and violating those rules can void the notarization entirely.
Rules on notarizing for family members are murkier. Some states flatly prohibit notarizing documents for spouses, parents, children, or siblings. Others don’t ban it but strongly discourage it because the appearance of partiality alone can invite a challenge. The safest approach is to use an unrelated notary for every estate planning document, even when state law might technically allow a family member to serve.
Acknowledgments, Jurats, and What They Cost
Estate planning documents use two types of notarial acts. An acknowledgment is the more common type for deeds, trust documents, and powers of attorney. You confirm to the notary that you signed the document willingly for its stated purpose. You may have signed beforehand; the notary doesn’t need to watch your pen hit the page. They are certifying that you appeared in person, proved your identity, and acknowledged the signature as yours.
A jurat is used for self-proving affidavits and other sworn statements. It requires you to sign in the notary’s presence and to take a verbal oath or affirmation that the contents of the document are true. The notary must administer that oath out loud, and you must respond out loud. Signing before the appointment and swearing to it later doesn’t satisfy the requirement.
After the signing, the notary applies their official seal, signs the certificate, and records the transaction in a journal entry that typically includes the date, type of document, names of all parties, and the identification used. This record serves as backup evidence if the notarization is ever questioned.
Most states cap notary fees by statute. Maximum fees for acknowledgments and jurats range from $2 to $25 per signature, with the majority of states falling in the $5 to $15 range. States that don’t set a maximum leave the fee to the notary’s discretion. If you hire a mobile notary who travels to your home, hospital, or care facility, expect to pay an additional travel fee that typically runs $25 to $100 on top of the per-signature charge, plus possible surcharges for after-hours or weekend appointments.
Remote and Overseas Notarization
More than 40 states now authorize remote online notarization, which lets a signer appear before a notary via live audio-video technology instead of in person. For estate planning, this is most useful when a testator is homebound, lives in a rural area without convenient notary access, or is executing documents while living overseas.
Remote sessions are recorded, and most states require the notary to retain that recording for at least ten years. Identity verification is more rigorous than in person: signers typically must pass both knowledge-based authentication questions and a credential analysis of a government-issued ID.
A smaller number of states have adopted some version of the Uniform Electronic Wills Act, which allows wills themselves to be signed and witnessed electronically, with the self-proving affidavit completed in the same remote session. Remote online notarization is widely available for powers of attorney, trust documents, and deeds, while electronic wills remain available in a limited but growing number of states.
If your documents need recognition in a foreign country because you own property abroad or your beneficiaries live overseas, you will likely need an apostille certificate or authentication. For countries party to the 1961 Hague Convention, an apostille from the secretary of state in the state where the document was notarized is the standard process for state-issued documents.2U.S. Department of State. Preparing a Document for an Apostille Certificate For countries outside the Hague Convention, a more involved chain of authentication applies.
Americans living abroad can use notarial services at U.S. embassies and consulates, which function like a domestic notary public. You must appear in person; embassies do not offer remote or virtual notarization, and you should bring your documents unsigned.3U.S. Department of State.
