Am I allowed to ask for a signer's thumbprint for my Notary journal?

Photo of woman with long dark hair on phone. She is looking at papers in her hand. Text on image reads NNA Hotline Tip.

I’ve been brushing up on Notary skills using “The Complete How-To Guide for Notaries” and it mentioned that I need to refer to the Notary Handbook to see if my state allows thumbprints in the Notary journal entry. I can’t find any reference in the Colorado Notary Handbook as to whether this is allowed or not. Can you please advise on this? — T.B. , Colorado

Colorado does not require, nor prohibit a thumbprint being added to the Notary journal.

California is the only state that requires a signer’s thumbprint for journal entries, and only when the notarized document is a power of attorney, deed, quitclaim deed, deed of trust or other document affecting real property.

In any state where thumbprints are not mandatory for journal entries, Notaries should respect a signer’s privacy if a signer chooses not to provide a thumbprint for the journal. 

Because of increasing identity theft and growing public concern over the protection of personally identifiable and private information, the NNA recommends that Notaries not ask individuals for a journal entry thumbprint unless specifically required for the notarization. For more information, please see our article on 3 important things Notaries need to know about journal thumbprints.

Hotline answers are based on the laws in the state where the question originated and may not reflect the laws of other states. If in doubt, always refer to your own state statutes. – The Editors

I think no matter what state if the notary wants to ask for a fingerprint because they feel something not quite right they should be able to.

Hello. Please note that Illinois, North Carolina and Texas have laws specifically prohibiting Notaries from taking signer thumbprints for journal entries.

With regard to my comment about me siging for a person unable to sign, here is the state law that supports it: RCW 64.08.100 Acknowledgments by persons unable to sign name. Any person who is otherwise competent but is physically unable to sign his or her name or make a mark may make an acknowledgment authorized under this chapter by orally directing the notary public or other authorized officer taking the acknowledgment to sign the person's name on his or her behalf. In taking an acknowledgment under this section, the notary public or other authorized officer shall, in addition to stating his or her name and place of residence, state that the signature in the acknowledgment was obtained under the authority of this section. [ Here is the law that the editor mentioned: RCW 42.45.070 Individual unable to sign—Signature. Except as otherwise provided in RCW 64.08.100, if an individual is physically unable to sign a record, the individual may direct an individual other than the notarial officer to sign the individual's name on the record. The notarial officer shall insert "signature affixed by (name of other individual) at the direction of (name of individual)" or words of similar import. I hope this clears things up for everyone. Sorry for not mentioning the RCWs in Washington State

In response to Patrick's comment, are we allowed as notaries to sign in the journal for clients who cannot sign themselves? I've never heard of that. I've been a notary with the state of Iowa and I've never signed for someone who couldn't sign my journal. Do states allow that? Couldn't that possibly considered conflict of interest of sorts if you're performing both the notarial act AND signing on behalf of the signer?

Hello. No, Patrick's comment was describing a 'signature by mark' notarization where a signer unable to physically write their name makes a mark such as 'X' on a document and then requests the mark be notarized. Iowa does not require a journal of notarial acts, and therefore does not provide rules for entering information in an optional Notary journal entry. However, if a person wishes a signature on a document notarized, but is physically unable to write, the state provides the following rules for signing and notarizing a document using a process known as 'signature by proxy'. Please note that these rules address a person unable to write signing a document, and do not address signing a name in an optional Notary journal entry. “If an individual is physically unable to sign a record, the individual may direct an individual other than the notarial officer to sign the individual’s name on the record. The notarial officer shall insert ‘Signature affixed by (name of other individual) at the direction of (name of individual)’ or words of similar import” (IC 9B.9).

My state doesnt say Yeah or Neah, but I make it a point to get one from clients who cannot sign themselves due to physical reasons and I have to sign on their behalf, or from those who sign with an "X" to guard against fraud.

Although my state does not require a thumbprint, it doesn't say I cannot ask for one. If the signer(s) are reluctant to provide one I let them know it's okay if they don't want to provide one. Over the years, only two have declined to do one. Not bad....
