To add a name to a document in the United States, the individual must physically appear before a notary public, sign the document in their presence, and provide valid identification. The notary will then affix an official seal or stamp to verify the signature. Fees typically range from $10 to $20 per document, depending on the state and notary’s rates. Additional costs may apply for services like document preparation or certification for international use.

The process ensures legal validity by requiring in-person verification to prevent fraud. According to the National Notary Association (NNA), the average notary fee in 2023 was $15.50, with states like California ($10 minimum) and New York ($15 minimum) setting lower bounds. Higher costs often correlate with urban areas or specialized certifications, such as apostille services, which range from $20 to $50. For example, the U.S. Department of State reports that 75% of states charge between $10 and $20 for basic notarization, while international certifications like apostille can cost up to $100. Legal requirements vary by document type; wills, power of attorney, and real estate deeds often incur higher fees due to complexity. The American Bar Association emphasizes that proper name addition safeguards against disputes by ensuring compliance with federal and state identity verification standards. In summary, while core notary fees are standardized, additional services and regional regulations influence total costs.
