Mobile notaries are necessary when entering in to a legally binding agreement in Florida. They validate your signature on legal documents as authentic and official by witnessing or acknowledging your identity.
A Florida notary will look for certain language in your document to determine if a notarization is needed. If you want to be safe, you can have any document notarized. The notarization just adds another level of security to the agreement by officially confirming the identity of the people who signed.
