Notary vs. Attorney: Which One You Need, and When Both

People often aren't sure whether they need a notary, an attorney, or both. The short version: a notary verifies identity and witnesses a signature, an attorney drafts documents and gives legal advice. Here's how to tell which one you actually need.

What a Notary Does

A notary public verifies the identity of the person signing a document, confirms they're signing willingly and knowingly, and witnesses the signature with an official seal. A notary doesn't draft documents, doesn't give legal advice, and doesn't review whether a document is fair, complete, or in your best interest, only that the right person is signing it under their own free will.

What Only an Attorney Can Do

An attorney drafts and reviews legal documents, explains what specific clauses mean and how they affect you, represents you in a dispute or court proceeding, and advises you on strategy, for example how to structure a will to minimize estate complications, or what terms to negotiate in a contract.

When You Need Both

Most estate planning, complex real estate transactions, and business agreements benefit from an attorney drafting or reviewing the document, then a notary formally witnessing the signature. A common example: an attorney drafts your will and power of attorney, explains what each document does, and then a notary (sometimes the same day) notarizes your signature and coordinates witnesses.

Frequently Asked Questions

Can a notary explain what I'm signing?

A notary can confirm you understand you're signing the document and point out where to sign, but can't explain legal terms or give advice about whether the document serves your interests. Those questions should go to an attorney.

Do I need an attorney to write a simple power of attorney?

Not always, many people use a standard form for a straightforward power of attorney. But if your situation is complicated, blended families, significant assets, business interests, an attorney's input is worth the cost to make sure the document actually does what you intend.

Is a notarized document automatically legally binding?

Notarization confirms the signature is genuine, it doesn't make an otherwise invalid or poorly drafted document enforceable. The document's legal effect depends on how it was written, which is where an attorney comes in.
