In most cases, no. Notaries should refuse to notarize documents that are incomplete or contain blank spaces in the main body of the document, because doing so can enable fraud and may violate state law. However, there are limited exceptions depending on the type of blank space and state requirements.
Should I notarize a document that has blank spaces?
You should not notarize an incomplete document due to the risk of fraud. For example, if a document selling a vehicle to someone else for an agreed amount was signed and notarized with the selling price left blank, a dishonest person could fill in a different amount later and claim that was the agreed-upon sum of money.
Is it illegal to notarize a document with blank spaces?
Many states prohibit notarizing a document that is incomplete or contains blank spaces.
In California, the Secretary of State’s 2024 Notary Public Handbook instructs Notaries to refuse to notarize if the Notary knows a document is incomplete.
In Colorado, Colorado Revised Statutes 12-55-107 authorizes disciplinary action against a Notary who “notarizes any blank document.” The statute says, “The secretary of state or the secretary of state’s designee may deny the application of any person for appointment or reappointment or take disciplinary or nondisciplinary action against a notary public if the notary public: …(g) Notarizes any blank document;…”
If you are presented with an incomplete document, you should refuse to notarize citing the missing pages or blank spaces. Even if you are commissioned in a state that does not provide specific guidance regarding blank document spaces, such as Texas, Article IV-D-1 of The Notary Public Code Of Professional Responsibility recommends: “The Notary shall refuse to notarize a signature on any document that is blank or incomplete.”
What type of blank spaces are allowed in notarized documents?
There are some limited situations where it is permissible to leave a space blank, such as the following:
Spaces for additional signatures. Documents often need to be signed by multiple individuals at different times in different locations. You may be asked to notarize one signature on a document that includes additional blank signature spaces. In such a case, the document is not considered incomplete, and you may complete the notarization for any signers who are physically present and properly identified. However, you should record in the journal entry that the document included additional signature spaces and why they were not used.
Spaces reserved for use by government officials. Some documents include a boxed-off section or separate area of blank spaces marked with a title such as “For Official Use Only,” “Reserved For Recorder Use Only” or some other label indicating it may only be completed by an authorized official. If you are asked to notarize such a document, it is OK to proceed without filling in the blanks in a section reserved for official use.
Exceptions in state law. Some states permit certain documents that include blanks to still be notarized. For example, Florida prohibits notarizing most documents that include blank spaces, but FS 117.107(10) allows exceptions for an endorsement or assignment in blank of a negotiable or nonnegotiable note and the assignment in blank of any instrument given as security for such a note.
What happens if a Notary notarizes an incomplete document?
Never leave blanks or omit information when you are completing the notarial certificate wording. Missing information in the notarial wording was listed by California county recorders as one of the top reasons notarized documents are rejected by recording offices.
Can a Notary fill in blank spaces on a document?
No, a Notary may not fill in blank spaces in the main body of a document. Remember that you may only complete information in the notarial certificate wording. Any blanks in the main text must be completed by the signer or another authorized individual before notarization may proceed.
To avoid fraud, document rejection, or disciplinary action, Notaries should ensure all required information in the document is complete before notarization. When in doubt, Notaries should refuse the notarization and advise the signer to complete the document or seek legal guidance. Always follow the laws and administrative rules of your commissioning state.
