Notarizing A Signature By Proxy: What You Need To Know

signature-by-proxy-resized.jpgUpdated 10-4-21. There are times when a person needs to sign a document and have it notarized immediately, but the person is unable to write at all. Some states allow signers who can’t write to use an option called signature by proxy, where someone else present signs on behalf of the person who is unable to write. Here are answers to the most common questions about signatures by proxy. 

How Does A Signature By Proxy Work?

The basic idea is that since the person requesting the notarization is physically unable to write, they direct someone else to sign the document as their proxy.

What Do State Notary Laws Say About Proxy Signatures?

Depending on state laws, there are different restrictions for who may act as the proxy.

In Florida, Michigan and Texas, the disabled person must direct the Notary to sign the document on the disabled person’s behalf. Florida also requires a signature by proxy to be witnessed by two other people with no interest in the document. Texas also requires a single disinterested witness who must provide the Notary with proof of identity in the same way as the signer. Michigan does not require additional witnesses for a signature by proxy.

All three states require a Notary signing by proxy to include a statement on the document that the signature was affixed by the Notary. For example, Florida Notaries must write “Signature affixed by notary, pursuant to s. 117.05[14], Florida Statutes” below the signature.

Hawaii allows a Notary to sign as a proxy, but the Notary must be provided with a doctor’s written certificate that the person is physically unable to sign or make a mark but can communicate their intention to the Notary.

In Colorado and Minnesota, a third party — not the Notary — must sign the document at the disabled person’s direction while the disabled person and the Notary are present. The words “Signature attached by (name)” or “Signature written by (name)” must be included under or near the signature. Minnesota also allows the third party to use the individual’s signature stamp to make the signature by proxy. North Carolina requires a disinterested third party to be the signer by proxy and to sign the document in the presence of the Notary and two other witnesses unaffected by the document.  

Do not notarize a signature by proxy in states whose Notary laws do not provide statutory guidelines, such as Pennsylvania. Always check your laws before proceeding to notarize signatures by proxy. For example, California's Notary laws do not provide statutory guidelines for signatures by proxy involving general documents, but California Probate Code 4121 allows a signature by proxy to be used for signing power of attorney documents only, provided the signature is made by another adult in the principal signer's presence and at the principal signer's direction. 

Is A Signature By Proxy The Same As A Power Of Attorney?

No. A power of attorney gives someone legal power to sign documents and make decisions on behalf of another individual. Asking someone to sign as a proxy does not give the proxy power to make decisions for the signer.

Is A Signature By Proxy The Same As A Signature By Mark?

No. Unlike a signature by mark, a signature by proxy is normally only used when a signer is completely unable to write, including being unable to make a mark such as an “X.”

Can Someone Hold Or Guide A Signer’s Hand Instead Of Using A Proxy Signature?

No. It is never appropriate for another person to physically hold and move a signer’s arm to make a signature if the signer is unable to write without help. If someone asks you to notarize a signature made this way, you must tell them no.

As someone who works with a funeral home, many of my clients are elderly and/or in poor physical shape. Can anyone at NNA tell me if there is any similar law in Indiana? It would be a big help!

National Notary Association

02 Jul 2018

Hello. Indiana's Notary Public Guide states that a signer may use a stamped signature and have it notarized: "Q: May the signer use a signature stamp on the document they want notarized? A: Yes, a signature on a tangible record is a tangible symbol. A stamp, mark or other indication of execution is sufficient." See page 36 for more information:

Does California allow a signer to use a signature stamp?

National Notary Association

02 Jul 2018

Hello. California Notary law does not authorize Notaries or signers to use a signature stamp for notarizations. However, California does permit a signer who is unable to write his or her name to acknowledge their signature by making a mark in the presence of two witnesses. (California Civil Code section 14.)

Just recently saw a caregiver, stamp the client's signature in her presence. I asked her to sign behind the lady and also my journal entry for this transaction. I'm in Louisiana

When the notary signs a large package of documents on behalf of the disabled's behest, is the state statute verbiage required below all signature lines or only those documents that require a notary seal? My initial thought is that each signature would indeed require the verbiage.

Hi NNA, When someone asked me to help with a POA signing of a paraplygic many years ago, I turned to the NNA for assistance. At the time, I was told that we could indeed sign with a proxy even though I'm in CA. Per your advice at that time, we used probate code 4121-B which states: "(b) The power of attorney is signed either (1) by the principal or (2) in the principal’s name by another adult in the principal’s presence and at the principal’s direction." That code is still in effect, so the article above with reference to CA may be a bit misleading.... Hope that helps!

Hi Terrie, thank you for your message. While the article is primarily focused on signature by proxy provisions in state Notary statutes, you are correct about the CA Probate Code provision. We've updated the article to include the provision about power of attorney documents in California. California is a challenging state to report on because there are isolated Notary provisions included in many of CA's separate Codes.

What about an e signature. Can the signer direct his/her name be electronically generated and placed as an e signature at the time of the notarization, with the notary then printing the document and affixing his/her signature in ink and the stamping?

Can you elaborate on California law not authorizing a signer to use a signature stamp? Where I might site this law? Couldn't a signature stamp technically be a "signature by mark"? A mark being "any symbol made by the signer that represents execution of the document such as an ‘X’, a scribble, a stamp, or even a thumbprint." Thank you!

The information regarding Idaho is incorrect. I.C. Section 51-109 states the individual who cannot sign may direct an individual *other than the notary public* to sign the individual's name.

My Sister in Law was taking Care of my quadriplegic Mother in law before my mother in law passed. While my mother in law was in the hospital before she passed, my sister in law moved a bunch of assets such as vehicles in to my sister in laws name without my mother in laws knowledge . This is in California , Did there 1) need to be a Notary present for the asset transfer signature 2) can this be considered a Proxy signature even though no proof of consent exists ?

With the signature by proxy being allowed for power of attorney in CA, being that the thumbprint is required for the notary journal, does the proxy also leave the thumbprint for the principal?

National Notary Association
