Electronic signatures

Is an e-signature on a change order valid? ESIGN, UETA, typed names and finger signatures

Yes, as far as the signature being electronic goes. The federal ESIGN Act, 15 U.S.C. section 7001(a), says that for any transaction in or affecting interstate or foreign commerce, "a signature, contract, or other record relating to such transaction may not be denied legal effect, validity, or enforceability solely because it is in electronic form", and "a contract relating to such transaction may not be denied legal effect, validity, or enforceability solely because an electronic signature or electronic record was used in its formation."

States have their own version, the Uniform Electronic Transactions Act, published by the Uniform Law Commission. California's is Civil Code section 1633.1 and following, and section 1633.7 puts it in two sentences: "If a law requires a record to be in writing, an electronic record satisfies the law. If a law requires a signature, an electronic signature satisfies the law." This page does not say how many states have enacted UETA, because that count could not be confirmed at the Commission's own page on the read date. ESIGN is federal and applies nationwide either way.

A typed name and a finger-drawn signature both fall inside the definition. ESIGN defines an electronic signature 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" (section 7006(5)), and California's UETA uses the same definition (Civil Code section 1633.2(h)). The test is intent and attachment to the record, not the shape of the mark. No statute read for this page lists a typed name or a finger-drawn mark by name, so this page does not claim the law "specifically" allows either. It says what the definition says: a symbol adopted with the intent to sign, attached to the record, is a signature.

This page explains the rule in plain words. It is not legal advice. And an electronic signature does not, by itself, make a change order valid: a state rule about what the order must contain still applies, and California's is on the California page.

Coming to the Jobber App Marketplace.

What makes an electronic signature valid

Four things, each from the statute text (15 U.S.C. section 7001 and section 7006).

And one limit the statute puts on itself. Section 7001(b)(1): ESIGN does not affect any legal requirement "other than a requirement that contracts or other records be written, signed, or in nonelectronic form." Read against a state rule like California's, that means ESIGN removes the paper-and-ink objection and nothing else. A change order that must state its scope, its amount and its effect on the schedule must still state them, electronic or not. Both rules have to be met.

California's UETA says the same from the state side. Civil Code section 1633.7 (section 1633.7): an electronic record satisfies a law that requires a writing, and an electronic signature satisfies a law that requires a signature. Its definition of an electronic signature, section 1633.2(h) (section 1633.2), reads "electronic record" where ESIGN reads "contract or other record" and is otherwise the same.

What a text-message "yes" is, and is not

A text that says yes, ok or go ahead is consent to the work. It is not an agreed price unless the price is in the record the customer said yes to, and it is not a change order under a state rule that requires the order to state its scope, its amount and its effect on the schedule. A yes with no price and no new total is a conversation, not a change order, even when it is in writing.

The problem with a text yes is not the signature. It is that there is no record with the scope, the price and the new total for the signature to attach to. Whether a one-word reply counts as a signature to some record is a question about which record it was attached to, and this page does not answer it. It does not need to: put the three things in one record, and the yes has something to sign.

The spoken yes is answered by the statute directly. Section 7001(c)(6): "An oral communication or a recording of an oral communication shall not qualify as an electronic record for purposes of this subsection except as otherwise provided under applicable law." So for the consumer-consent rules above, the homeowner's yes on the phone, even recorded, is not an electronic record.

What to keep

The retention rule in section 7001(d)(1) wants a record that accurately reflects what was agreed and stays accessible, in a form that can be reproduced later. For a change order that means keeping, with the job:

The free paper template holds the record and the two ink signatures; a photo of the signed page sent to the customer's phone is their copy. For shops on Jobber, Volta Change Orders builds the record this way: the customer signs with a finger or types their name and taps Approve, and the app keeps that signature with the change, along with the name on the job, the time, the internet address and the kind of device it came from, as the approval record. The help center describes it, in English and in Spanish. The app does not replace a written contract; if your contracts call for a particular form of signature, check with whoever wrote them.

How the field-service tools capture a signature

Each of these is the vendor's own help page, read on 2026-09-22. Jobber: in client hub the client "can select to draw or type their name to approve", and in person the tech can collect a signature on their own device, where the client can "draw to sign to approve the quote" (Quote Approvals). Jobber's page also says that editing an approved quote removes the client's signature from the quote and from client hub, and keeps the earlier signed version as a PDF in an internal note; that PDF is the copy that survives an edit. Workiz: "Signatures are automatically required for all estimates approved through the client portal. You will not be able to disable the signature requirement. Once signed, the signature will appear on the estimate document itself." (Estimates FAQ). ServiceTitan: customers sign documents from a link to its Visit Assistant, finger-drawn on a mobile device and typed on a computer, and its page adds: "If you are using e-signature by email, your customers are limited to typing their name as a signature rather than physically signing it." (Use the contactless experience). The same page says online estimates are not accessible through that link, and ServiceTitan's change order is an estimate; no page reconciling the two was found.

None of these pages says which form of signature a given state accepts. That is the statute's job, above. The full comparison, tool by tool, is on how the tools compare.

Questions

Is a typed name a legal signature?

ESIGN defines an electronic signature as an electronic sound, symbol or process attached to or logically associated with a record and adopted by a person with the intent to sign it (15 U.S.C. section 7006(5)). A typed name in a signature box falls inside that on its face. No statute read for this page lists a typed name by name, so this page does not say the law specifically allows one; it says the definition turns on intent and attachment, not on the shape of the mark. Whether a typed name meets your own contract's signature clause is a question about your contract.

Is a finger-drawn signature on a phone treated differently from a typed name?

Not by the statute text read for this page. Both are a symbol adopted with the intent to sign and attached to the record, which is the whole of the definition in ESIGN section 7006(5) and California Civil Code section 1633.2(h). What differs is what you keep with it: the name, the time, the device and the internet address are what tie either kind of mark to a real person at a real moment.

Does the customer have to agree to sign electronically first?

Where a law requires the record to be given to the consumer in writing, section 7001(c)(1) requires the consumer's affirmative consent, a clear and conspicuous statement of their rights beforehand, and a statement of the hardware and software needed, with consent given or confirmed electronically in a way that shows they can open the record. Section 7001(c)(3) adds that a contract is not invalid solely because that electronic confirmation was missed. Whether a change order is such a record depends on the state rule that reaches it.

Does a recorded phone call count as an electronic record?

For the consumer-consent rules, no. Section 7001(c)(6): "An oral communication or a recording of an oral communication shall not qualify as an electronic record for purposes of this subsection except as otherwise provided under applicable law."

Does an e-signature make a change order valid in California?

It settles the signature question and nothing else. Civil Code section 1633.7 says an electronic signature satisfies a law that requires a signature, and ESIGN section 7001(b)(1) leaves every other legal requirement in place. In California a change order on a home improvement contract must still be in writing and signed before the work it covers begins, and must state its scope, the amount added or subtracted, and the effect on the progress payments or the completion date. The California page quotes those sections.

What should the signed record hold?

The change in one line, the price of this change, the new job total and the effect on the schedule; the name of the signer and the time; the device and the internet address; the signature image or the name as typed; and a copy for the customer. That is the shape section 7001(d)(1) asks for: a record that accurately reflects what was agreed and stays accessible and reproducible later.
