What Is a Notary Letter?

A notary letter (also called a notarized letter) is a document that has been signed in the presence of a licensed notary public, who then stamps and countersigns it to confirm its authenticity. The notary's role is not to verify the content of the letter, but to verify the identity of the signer and witness that the signature was made voluntarily and without duress.

Notary letters are a critical part of the legal and administrative world. They add a layer of trust to documents that need to be taken seriously — by courts, employers, government agencies, financial institutions, and foreign authorities.

Common Types of Notary Letters

  • Affidavit letters — sworn written statements of fact
  • Authorization letters — granting someone permission to act on your behalf
  • Consent letters — such as parental consent for a minor to travel
  • Residency or income verification letters
  • Demand letters — formal requests for payment or action
  • Letters for visa or immigration applications

When Do You Need a Notary Letter?

Not every formal letter requires notarization, but there are specific circumstances where it is either required or strongly recommended:

  1. Real estate transactions — Deeds, mortgage documents, and transfer agreements often require notarization.
  2. International documents — Many foreign governments require notarized (and sometimes apostilled) documents before they will accept them.
  3. Legal proceedings — Courts may require affidavits or sworn statements to be notarized.
  4. Child travel consent — If a minor is traveling with only one parent or with a guardian, a notarized consent letter from the other parent is typically required.
  5. Powers of attorney — Most jurisdictions require these to be notarized to be legally valid.
  6. Financial agreements — Some loan agreements and financial contracts require notarized signatures.

What a Notary Does NOT Do

It's important to understand the limits of notarization. A notary public does not:

  • Provide legal advice or review the content of your document
  • Guarantee the accuracy or truthfulness of the document's claims
  • Act as a lawyer or advocate for either party

If you need legal advice about the content of your document, consult a qualified attorney.

How to Get a Letter Notarized

The process is straightforward and typically takes less than 30 minutes:

  1. Prepare your document — Write and finalize the letter, but do not sign it yet. You must sign in front of the notary.
  2. Bring valid photo ID — A government-issued ID such as a passport or driver's license is required.
  3. Locate a notary — Banks, law offices, shipping stores (like UPS or FedEx), libraries, and courthouses often have notaries on staff. Online notarization is also widely available.
  4. Sign in the notary's presence — The notary will witness your signature, verify your identity, and apply their official stamp and signature.
  5. Pay the fee — Notary fees are typically modest, often ranging from a few dollars to around $15–$25 per signature depending on your location.

Online Notarization: A Modern Option

Remote Online Notarization (RON) is now legal in many U.S. states and increasingly available internationally. Platforms allow you to connect with a notary via video call, verify your identity digitally, and receive a notarized document electronically. This is particularly useful for time-sensitive documents or when you cannot easily travel.
