for notarial of documents or affidavit, how much is the regular fees for these?

Answer 1

This may vary from state to state, however, a private notary (not government employeed) may charge $2.00 per notarization.

So, if there is 3 notarizations for one document you can charge $6.00.

However, there is a lot of notaries who violate this rule. If so you can report the abuse to your Secretary of State.

Answer 2

The fee depends on the kind of affidavit one has to notarize.
