The average cost to notarize a power of attorney in the United States ranges from $10 to $20, with additional fees for certification or complex documentation. State-specific rates and document complexity influence final pricing.

The variation in notary fees stems from state laws and notary service policies. For instance, California mandates a $15 per Notary Public fee, while New York caps charges at $10. The National Notary Association reports that 60% of notaries charge between $10 and $20 for basic notarization, with 15% charging more for additional services like certification or attestation. Complex documents, such as multi-page powers of attorney or those requiring witness signatures, often incur higher fees. A 2023 survey by the National Association of Secretaries of State found that 42% of states allow notaries to charge based on document complexity, while 38% enforce flat rates. Additionally, mobile notaries or those offering off-hour services may add $10-$30 in travel or convenience fees. These rates reflect standard practices and ensure compliance with federal and state notary laws, which require notaries to maintain impartiality and accuracy during the process.
