The fee to notarize a signature on a document is $15 per notarized signature. For example, if two people are signing the same document, the fee is $30. In cases of real estate purchases, the total number of signatures can be large, but most of the signatures are not notarized.
Every person requesting notarization of their signature must have a valid, unexpired photo identification. The most common forms of ID are: driver's license and passport. Some forms of military ID are acceptable, but they must contain the photo and signature of the person. If you do not have a valid, unexpired ID, you may bring two people with you who have a valid ID who can sign a statement confirming your identity.
Employers across the country hire people who are unable to appear in person at the employer's office. In order to verify a prospective employee's eligibility to work, they ask the employee to bring their I-9 form to a notary public to verify their identification documents such as their driver's license and passport. A notary public is prohibited from offering this service unless the notary is ONLY notarizing your signature and nothing else. You can hire an Immigration Consultant or an attorney for I-9 services.
I perform notary public services almost always in my office. In some rare cases, I can travel. If you need a mobile notary, contact me, and I can refer you to one if I am not available.
