A notary public is a public official authorized to witness and certify the signing of important documents.

Various documents such as wills, contracts, deeds, powers of attorney, affidavits, and more may require notarization.

It depends on the notary public or the organization providing the service. Some may accept walk-ins, while others may require appointments.

Typically, you'll need to bring a valid form of identification such as a driver's license or passport. Additionally, bring the document(s) that need to be notarized, but don't sign them until you're in the presence of the notary.

Fees for notary services can vary, so it's best to inquire about the cost beforehand. Some notaries charge per signature, while others have a flat fee.
