Is a Typed or Drawn Signature Legally Binding?

This page quotes what the statutes actually say, with a link to each source, so you can check any statement yourself. It explains the law in general terms — it is not legal advice, and it can’t tell you how the law applies to your particular document. For that, ask a lawyer in your jurisdiction.

The law does not describe what a signature looks like

This is the part that surprises people. Neither of the two US statutes governing electronic signatures says anything about appearance — not that it must be cursive, not that it must resemble your handwriting, not that it must be an image at all.

The federal ESIGN Act defines an electronic signature at 15 U.S.C. § 7006(5) as:

“an electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record.”

The Uniform Electronic Transactions Act (UETA), adopted by every state except New York, uses materially the same wording. California’s enactment, at Cal. Civ. Code § 1633.2(h), defines it as:

“an electronic sound, symbol, or process attached to or logically associated with an electronic record and executed or adopted by a person with the intent to sign the electronic record.”

Read those definitions again and notice what is absent. There is no requirement that the mark look like anything in particular. “Sound, symbol, or process” is deliberately broad — a spoken confirmation, a typed name, a drawn line, a checkbox, or a process such as clicking a button can each satisfy it.

The operative words are “with the intent to sign the record.” That is the test. Appearance is not.

So which forms qualify?

On the statutory language above, all of these can be electronic signatures:

• A typed name. Typing your name into a signature field, with intent to sign, meets the definition. Choosing a script font changes nothing legally — it is a design choice, not a legal one.
• A drawn signature. Tracing your signature with a mouse, trackpad or finger. It rarely looks like your pen signature, and it does not need to. If you want a reusable image of either kind, typed in a script font or drawn, our free signature generator makes one in seconds; the law treats the two the same.
• An uploaded or photographed image of your handwritten signature.
• Initials, where a document calls for them.
• A clicked button or checkbox, where the surrounding record makes the signing intent clear.

None of these is inherently “more legal” than another. A wobbly finger-drawn line carries no more weight than a typed name, and neither carries less. If the document in front of you is a Word file, the same forms carry straight over — how to sign a Word document electronically walks through them.

What actually determines enforceability

If appearance is not the test, what is? Commentators generally summarise the statutes as requiring four things:

Intent to sign. The person meant their action to be a signature. This is the requirement written directly into both definitions above.

Consent to transact electronically. For consumer transactions, ESIGN sets out specific disclosure and consent requirements at 15 U.S.C. § 7001(c), including affirmative consent and disclosure of hardware and software requirements.

Attribution. The signature must be connectable to the person who made it. UETA addresses this directly — attribution is shown “in any manner, including a showing of the efficacy of any security procedure applied.” In practice this is what an audit trail is for: the email address the invitation went to, the IP address, the timestamp, the authentication method.

Retention and accurate reproduction. ESIGN’s record-retention rule is at 15 U.S.C. § 7001(d) — the record must remain accessible and accurately reproducible by those entitled to it.

Whether any given signature meets these is a question about your specific facts, not about the font.

Legal is not the same as defensible

A typed signature is legally capable of binding a contract. That is a different question from whether you could prove it in a dispute.

If someone later denies signing, the argument will not be about whether typed names count — the statute settles that. It will be about attribution: can you show it was them? That is where the surrounding evidence matters:

• Which email address received the signing invitation, and was it one only they control
• What IP address the signature came from, and when
• How they authenticated
• Whether the document has been altered since — which is what a cryptographic hash of the completed file demonstrates
• A complete event record: sent, opened, viewed, signed

This is why platforms produce a certificate of completion. The signature makes the contract; the audit trail makes it provable.

A note on terms, because they trip people here: a “digital signature” is not a stricter legal category — it is cryptography that strengthens the evidence behind an electronic signature. We take the two apart in electronic signature vs digital signature.

Signatura seals every completed document with a SHA-256 hash and records who signed, when, and from where — and the file can be re-verified by anyone holding it, without an account.

Outside the United States

The same principle — the law describes function, not appearance — holds in the other major frameworks.

The EU’s eIDAS Regulation (Regulation (EU) No 910/2014) provides at Article 25(1) that an electronic signature “shall not be denied legal effect and admissibility as evidence in legal proceedings solely on the grounds that it is in an electronic form.” It defines tiers by the technical assurance behind a signature, not by how it looks. We cover those tiers in eIDAS explained: SES vs AdES vs QES.

Canada’s framework works the same way — see Are e-signatures legal in Canada? for the federal and provincial position.

The exception that matters more than the format

A far more consequential question than what your signature looks like is what you are signing. Both ESIGN and UETA carve out categories of document where electronic execution is excluded or restricted — wills and testamentary trusts among them.

Those exclusions are set out at 15 U.S.C. § 7003, and we cover them in Are electronic signatures legally binding?.

If your document falls in one of those categories, the format of the signature is beside the point.

Frequently asked questions

Can I just type my name as a signature?

Yes — with the two things the statute actually asks for. A name typed into a signature field is “an electronic sound, symbol, or process” that has been “executed or adopted by a person with the intent to sign the record” under 15 U.S.C. § 7006(5). What makes it binding is that you meant it as a signature and that the record can be tied to you — intent and attribution — plus, in consumer transactions, ESIGN’s consent requirements at § 7001(c). What the characters look like plays no part.

Does an electronic signature have to look like my handwritten signature?

No. Neither ESIGN nor UETA says anything about appearance, so there is no requirement that what you type or draw resemble your pen-on-paper signature — a drawn line that looks nothing like it, a typed name and an uploaded image all sit on the same statutory footing. Visual comparison is not the test; intent and attribution are. If a dispute comes, the questions are who acted and whether they meant to sign, and those are answered by the record around the signature, not by comparing shapes.

Does using a cursive font make a typed signature more legal?

No. A script font is styling applied to the same typed characters, and neither statute says anything about typefaces. The definition — “an electronic sound, symbol, or process” adopted “with the intent to sign the record” — is met by plain text exactly as well as by a font that imitates handwriting. Signing tools render typed names in script fonts because it looks like a signature, not because it strengthens one: the font adds nothing to validity and nothing to evidence. The record behind the signature does both.

Is clicking “I agree” or ticking a box a signature?

It can be. The statutory word “process” covers click-to-sign: a button or checkbox, in a record that makes clear the click is meant as a signature, can be “executed or adopted by a person with the intent to sign the record.” What matters is the surrounding record — the page must show what was being agreed to, and preserve who clicked, when, and how they were authenticated. A checkbox with no signing context is a weaker record than a signature field, which is a difference of evidence, not of legal category.

What if someone else types my name — is that binding?

Not by itself. Under UETA’s attribution rule, an electronic signature “is attributable to a person if it was the act of the person” — a name typed by someone else, without your authority, was not your act and is not your signature. (Authorised signing is different: someone validly signing on your behalf is a matter of ordinary agency law, not of signature format.) If it happens, the dispute is factual — whose act was it? — which is exactly what attribution evidence exists to answer: the account that received the invitation, the authentication step, the IP address, the timestamps. And signing someone’s name without authority is no more lawful on a screen than on paper.

Will a typed signature hold up in court?

The statutory half is settled: under § 7001(a), a record or signature “may not be denied legal effect, validity, or enforceability solely because it is in electronic form” — typed ones included. What a court examines is the other half, attribution and integrity: was it that person’s act, and has the record changed since? Those are evidence questions, which is why the audit trail matters more than the signature’s shape: which address received the invitation, how the signer authenticated, when, from where, and a hash showing the file is unchanged. A typed name backed by that record is in a far stronger position than an elaborate drawn signature with none of it. What that record should contain is exactly what a certificate of completion exists to show.
