A notary is someone who witnesses the signing of documents and certifies that they are genuine. In a lot of cases, you will have to get a signature from someone who is signing over property or signing up for new services. A notary will come to your home or place of business and verify that everything looks legit, then sign their own name on the document as well.

The cost of getting a signature from someone who needs one varies depending on the type of document being signed (i.e., whether it's real estate, a marriage certificate, etc.). If it's something like an insurance policy, you may have to pay a deposit upfront before you can get the final signature. Otherwise, there is no extra fee for getting that first one done—once your money has been paid in full for all other signatures required, it covers all future signatures for that particular transaction!
