Key Takeaways
- A notary can only notarize documents where they witness your actual signature and confirm your identity in person — not documents you signed before arriving.
- Real estate deeds, powers of attorney, affidavits, and loan documents are standard signables, but wills and documents the notary has a financial stake in are not.
- Each state has its own list of what notaries can and cannot notarize, so a document legal in one state may be prohibited in another.
- The notary must see a government-issued photo ID and watch you sign the paper in front of them — remote notarization has different rules and is not available everywhere.
Real Estate and Property Documents
Deeds, mortgages, and property transfer forms are among the most frequently notarized documents. When you buy or sell real estate, the title company or closing attorney usually requires a notarized deed to prove the transfer was authorized by the actual owner. A notary witnesses your signature on the deed, confirms you are who you claim to be, and seals the document so the county recorder's office will accept it for filing.
Power of attorney forms related to property — documents that let someone else manage your real estate or handle a sale on your behalf — must also be notarized in most states. The notary's role is the same: verify your identity and watch you sign. Without the notary's seal, the document may be rejected by banks, title companies, or government offices.
Affidavits about property (sworn statements that something about the property is true) are signable, but only if you are swearing to facts you personally know. A notary cannot notarize an affidavit about something you heard secondhand or do not have direct knowledge of.
Financial and Legal Authority Documents
Powers of attorney — documents that give someone else legal authority to act on your behalf in financial, medical, or legal matters — must be notarized in most states. This includes healthcare powers of attorney, financial powers of attorney, and durable powers of attorney. The notary confirms you signed it willingly and understand what you are authorizing.
Loan documents, promissory notes, and mortgage applications often require notarization, particularly if the loan is large or involves real property. Banks and lenders use the notary's seal as proof that the person who signed is the actual borrower, not someone forging their name.
Affidavits — sworn statements used in court, for insurance claims, or to prove something officially — are signable as long as you are testifying to facts you know directly. Common examples include affidavits of identity, affidavits of loss (for a missing document), and affidavits for small estate proceedings. The notary does not verify whether what you are swearing to is true; they only confirm you signed it and understand you are swearing under penalty of perjury.
Travel and Custody Documents
Parental consent letters for minors traveling without both parents are frequently notarized. If a child travels with one parent, a grandparent, or another adult, the absent parent typically signs a notarized letter authorizing the trip. The notary confirms the signing parent's identity and that they signed willingly.
Custody agreements and modifications sometimes require notarization, depending on your state and whether the agreement is being filed with a court. A notary can notarize the signatures on a custody document, but they cannot notarize the agreement itself if it is a court order — only the parties' signatures on it.
Passport applications and certain visa documents may require notarized affidavits or declarations, though the rules vary by country and by the type of visa. Check with the embassy or consulate before having a document notarized for international travel.
Documents a Notary Cannot Notarize
Wills are not signable in most states. A will requires witnesses and specific legal procedures, but a notary's seal does not replace those requirements. Some states allow notaries to notarize the testator's signature on a will, but the will itself cannot be notarized as a complete document.
Documents the notary has a financial or personal interest in cannot be notarized. If you are a party to the transaction, a beneficiary, or stand to gain or lose money based on the document, you cannot notarize it. This rule exists to prevent fraud and conflicts of interest.
Blank documents or documents with blanks you plan to fill in later cannot be notarized. The notary must see the completed, final version and watch you sign it. If you sign a blank form and fill in details afterward, the notarization is invalid.
Documents you signed before meeting the notary cannot be notarized. The notary must witness your actual signature. If you arrive with a pre-signed document, the notary can only notarize your acknowledgment that you signed it — a different and weaker form of notarization.
Certain federal documents — such as federal tax forms, Social Security applications, and some immigration papers — have their own rules about notarization. Some cannot be notarized at all; others require a specific type of notary or certification. Always check the agency's website before assuming a notary can handle it.
How to Know if Your Document Is Signable
The safest approach is to ask the notary before you pay for the service. Most notaries will tell you over the phone or by email whether they can notarize your specific document. Bring the actual document with you — not a description of it — so the notary can review it.
If the document is required by a bank, title company, court, or government agency, contact that organization and ask whether notarization is required and what type. Some organizations have their own rules about which notaries they will accept or whether remote notarization is allowed.
Your state's Secretary of State office publishes rules about what notaries can and cannot do. These rules vary significantly by state, so a document that is signable in one state may be prohibited in another. If you are moving or working across state lines, check the rules for each state involved.
Remote Notarization and Special Rules
Remote notarization — where you sign the document via video call with a notary — is now legal in many states, but the rules are stricter than for in-person notarization. Not all documents can be notarized remotely, and not all notaries are authorized to perform remote notarizations. Real estate deeds, for example, cannot be notarized remotely in most states.
If you are considering remote notarization, confirm with the notary that your specific document is permitted under your state's rules. The notary will need to see your government-issued photo ID on camera and watch you sign the document on screen.
Some documents require a certified copy rather than a notarized signature. A certified copy is a photocopy of an original document that a notary or government official has verified as a true copy. This is different from notarization and has its own rules about which documents may have access to.
Frequently Asked Questions
Can a notary notarize a document I signed before I met them?
No, not as a standard notarization. A notary must witness your signature in person. If you arrive with a pre-signed document, the notary can notarize your acknowledgment that you signed it, but this is a weaker form of notarization and may not be accepted by banks or courts. Always sign the document in front of the notary.
What if the notary says they cannot notarize my document?
Ask them why. It may be prohibited by state law, it may have blanks that need to be filled in, or the notary may not be authorized for that document type. If you believe the notary is wrong, contact your state's Secretary of State office or the organization requiring the notarization and ask for clarification.
Do I need a notary if the document says "notarize if possible"?
That language usually means notarization is recommended but not required. However, if the document will be used in court or with a government agency, notarization may strengthen it even if it is not mandatory. Contact the organization that will receive the document and ask whether they require or prefer notarization.
Can a notary notarize a document in a language other than English?
This varies by state and by notary. Some notaries are authorized to notarize documents in other languages; others are not. The notary must be able to understand the document and communicate with you to confirm your identity and willingness to sign. Ask the notary before you arrive.
What happens if I get a document notarized that should not have been?
The notarization may be invalid, and the document may be rejected by the organization you are submitting it to. If you discover the error before submitting, contact the notary and ask them to correct it or provide a statement that the notarization was improper. If the document has already been filed or submitted, contact the organization that received it for guidance on how to proceed.
