Do contracts need to be notarized?
No, not as a rule. A contract is binding because the parties agreed to it, not because a notary stamped it, and the vast majority of business and consumer contracts in the US are never notarized. Notarization is required for particular documents, mostly ones that get recorded in public records, that grant someone power over your affairs, or that are sworn statements. Here's how to tell which is which.

The short answer
- Ordinary contracts don't need a notary. Service agreements, sales contracts, leases, quotes, NDAs and employment contracts are valid when signed by the parties.
- Some documents do. Deeds and other papers headed for the county recorder, many powers of attorney, affidavits and a few statutory forms are the usual cases.
- A notary doesn't make a contract legal. It adds proof of who signed. An unfair or invalid contract stays that way with a stamp on it.
- The other side may insist anyway. Lenders, title companies and agencies often require notarized signatures even where no statute does.
What a notary actually does
A notary public is a state-commissioned officer whose job is to confirm identity and record a formal act. The notary doesn't read your contract for fairness, explain it or vouch for its contents. Two notarial acts cover most documents:
- Acknowledgment. You appear before the notary, prove who you are and declare that you signed the document. This is the usual act for deeds and powers of attorney.
- Jurat (oath or affirmation). You swear or affirm before the notary that the contents are true, then sign. This is what makes an affidavit an affidavit.
Documents that commonly need a notary
| Document | Why a notary | Example |
|---|---|---|
| Deeds and other real estate records | Recorders won't accept them without proof the signature is genuine | Florida requires an acknowledgment, or proof by a subscribing witness, before an instrument concerning real property can be recorded (Fla. Stat. § 695.03). Texas has a similar rule for recording (Prop. Code § 12.001). |
| Powers of attorney | Banks and others need to rely on the agent's authority | Florida requires two subscribing witnesses and an acknowledgment before a notary (Fla. Stat. § 709.2105(2)). New York's statutory form must be acknowledged too (Gen. Oblig. Law § 5-1501B). |
| Affidavits | A sworn statement is made under oath before an officer | Any affidavit filed in court or with an agency |
| Self-proving will affidavits | Lets a will be admitted to probate without calling the witnesses | Florida's statutory form, signed by the testator and witnesses before an officer (Fla. Stat. § 732.503) |
| Some statutory lien waivers | The state wrote the form with a notary block in it | Wyoming's lien waiver, which must be substantially in the statutory form, ends with an acknowledgment before a notarial officer (Wyo. Stat. § 29-10-101(b)) |
Lien waiver rules in particular vary a lot from state to state. Before you add a notary step to every payment, check your own state's form, for example the pages on Wyoming and Texas lien waivers, and whether a waiver can be signed electronically.
Sworn statements without a notary
Even documents that look like they need a notary sometimes don't. Where a federal law or rule calls for a sworn statement, an unsworn declaration that the signer dates and signs as true under penalty of perjury usually works instead (28 U.S.C. § 1746). It doesn't cover depositions, oaths of office or oaths that must be taken before an official other than a notary.
I declare (or certify, verify, or state) under penalty of perjury that the foregoing is true and correct. Executed on (date). (Signature)
Many states have their own version. In Florida, where a law or court rule requires a document to be verified, a written declaration under penalties of perjury, printed at the end of the document and above the signature, generally does the job (Fla. Stat. § 92.525). Check the specific rule before relying on one: some filings still require a notarized oath.
Can the notarization be electronic?
Yes, where your state allows it. ESIGN and UETA both let a notary's electronic signature, with the other information the law requires, satisfy a notarization requirement (15 U.S.C. § 7001(g); UETA section 11). Whether the notary can work over video, and for which documents, is up to each state's notary law. Our guide to e-signing a document that needs a notary covers remote online notarization in detail.
What to do in practice
- 1
Ask what the document is for
If it will be recorded, filed with an agency, used in court or relied on by a bank, look up that office's rules. If it's an agreement between two businesses or a business and a customer, a notary is almost never required.
- 2
Read the form
Statutory forms such as lien waivers, powers of attorney and affidavits show their execution requirements on the face of the form: a notary block, witness lines or a declaration.
- 3
Ask the other party
A lender or buyer who wants a notarized signature will say so. It's cheaper to ask before signing than to redo the paperwork.
- 4
Sign the rest electronically
For everything else, an e-signature with a clear record of who signed and when is the practical choice.
Where SignMaster fits
SignMaster isn't a notary service and can't notarize a document. What it does is collect binding signatures on the agreements that don't need one: estimates, service contracts, change orders, leases and waivers. Each signer opens their own emailed link, can be asked for an access code first, and the finished PDF carries a certificate of completion with each signer's email, IP address and signing time. That isn't a notarization, but for an ordinary contract it's strong evidence of who signed.
General information, not legal advice
Notary requirements come from state recording, probate, power of attorney and lien laws, plus whatever the receiving office or company demands, and they change. Treat the examples here as illustrations of the rules, then check the current law and the recipient's requirements for your own document.
Questions? Answers.
Is a contract valid if it isn't notarized?
Yes. A contract's validity depends on agreement, consideration, capacity and a lawful purpose. Notarization isn't one of the ingredients unless a specific law requires it for that type of document.
Does notarizing a contract make it legally binding?
No. Notarization proves who signed and, for an oath, that they swore to the contents. It doesn't fix missing terms, an illegal purpose or a party who lacked capacity.
Do lien waivers need to be notarized?
In some states. Wyoming's statutory waiver form includes a notary acknowledgment, while many states' forms have none. Use the form your state's statute sets out, with whatever execution block it includes.
Does a power of attorney need to be notarized?
Usually, in practice. Florida and New York, for example, require an acknowledgment before a notary for the documents they govern, and many banks won't accept a power of attorney without one.
Can I get a document notarized after I e-sign it?
Generally the notary needs to watch you sign or have you acknowledge your signature in their presence, in person or by approved video. Arrange the notarization first and sign as part of it.
