A Texas notary's duty is to be an impartial witness to your signing, verify your identity, and ensure you are signing willingly. 

You cannot get a certified copy of a government document from a notary. You must contact the government agency that holds the original record. 

No, a notary cannot prepare legal documents or provide legal advice unless they are also a licensed attorney. 

You must present a valid government-issued ID. If you do not have one, a credible witness may be used to confirm your identity. 

In Texas, a notary may charge a maximum of $10 per document, with an additional $1 for each signature.
