Occasionally I will get a request from a borrower to notarize a document for them that is not part of the closing documents. No problem. I do it at no extra charge. I had such a request last night. It was actually for the borrower's mother.
First I completed the closing. Then I offered to notarize the document. It was a Quitclaim Deed. There was a problem though. The borrower's mother would have to sign with a mark, since she was unable to sign her name.
That itself is not a problem. A signature by mark can be used to sign a document (CRS 12-55-110.5).
The problem was that the borrower's mother has Alzheimer's, and was not fully aware of what she was signing.
A signature by mark is acceptable if a person has a physical limitation that prevents them from signing their name. But I couldn't accept it if the person doesn't understand what they are signing.
P.S. With more than 100 pages of loan documents to sign at closing, there are a lot of borrowers who would prefer to sign with a mark.
