In Washington State the law states we can only charge $10 for most notarial acts, including attesting a signature, affirmations, and acknowledgements. WAC 308-30-220
The Notary is allowed to charge a travel fee in addition to the notarial fee as long as long as both parties agree to it. This agreement must be done in advance of the signing. https://app.leg.wa.gov/wac/default.aspx?cite=308-30-220
