When a wet signature is still required — and when someone is just asking for one

The default is electronic, and has been for 25 years

The federal ESIGN Act and the state Uniform Electronic Transactions Acts do the same job from two directions: a signature, contract or record may not be denied legal effect solely because it is electronic. That covers almost everything anyone signs — employment contracts, NDAs, leases, purchase orders, settlements, terms of service. Whether such a signature holds up evidentially when someone denies making it is a separate question, answered in are electronic signatures legally binding.

This is about the residue: documents where electronic execution is either excluded by statute or refused in practice. Two problems, two fixes, and the first thing to establish about any request for ink is which one you are facing.

The statutory carve-outs, as they are actually written

ESIGN's exceptions live in 15 U.S.C. § 7003, and they are narrower than most summaries of them. Two subsections do the work.

Two things here surprise people. The first is how much of family law it sweeps in — not just the decree but the agreements around it. Prepare a child custody agreement for filing and the court's own signature rules decide the format.

The second is that these are exclusions from ESIGN, not prohibitions on electronic form. Section 7003 says the Act does not apply; it does not say ink is required. Where another statute has since authorised electronic execution for that document type — as electronic-wills acts have in a number of states — that statute governs. California's UETA says so in terms: an excluded transaction may still be conducted electronically if another applicable law permits it.

The notices list is the one nobody reads

The § 7003(b)(2) notices are unusual, because they are things you send rather than things you sign — and because they are exactly what a landlord, insurer or utility would most like to automate.

• Utility services. Cancellation or termination of water, heat or power.
• Credit and tenancy. Default, acceleration, repossession, foreclosure and eviction — but only under a credit agreement secured by, or a rental agreement for, a primary residence.
• Insurance. Cancellation or termination of health or life insurance benefits, excluding annuities.
• Product recalls. Recall, or notice of a material failure, where it risks endangering health or safety.

The primary-residence qualifier gets misread both ways. A default notice on a commercial lease or an investment property is not on the list; the same notice on the tenant's home is. It rarely decides anything alone: serve an eviction notice and the delivery method comes from the landlord-tenant statute, which is stricter than ESIGN anyway.

The UCC exclusion is broader than it looks

"Except Articles 2 and 2A" reads like a small carve-out from a carve-out. It is the other way round: sales and leases of goods stay inside ESIGN, and everything else in the Code sits outside it. Article 3, negotiable instruments, is the case that matters.

A promissory note meant to be negotiable takes its value from being a unique physical object: whoever holds the original may enforce it, and a copy is not the note. That model does not survive becoming a file that can be duplicated perfectly, so ESIGN handles it separately. Section 7021 creates the "transferable record" — an electronic note secured by real property that behaves like a negotiable instrument, but only where a system keeps one authoritative copy that is unique, identifiable and unalterable, identifies who controls it, and marks every other copy non-authoritative.

That machinery exists, and mortgage eNotes run on it at scale. It does not exist for an ordinary promissory note between two people — which is why lenders and note buyers still want the signed original in a vault, and why "lost note" affidavits are a standing category of document.

Half the ink in circulation is policy, not law

Once the statutory list is out of the way, the remaining demands come from institutions that have simply decided they want ink. They are not weaker for being unlegislated: an organisation that will not process your document is as final as any statute, and faster about it.

The clearest current example is US immigration. The Department of Homeland Security's rule on signatures for immigration benefit requests, effective 10 July 2026, requires a handwritten signature. Typed names, pasted images, stamps, autopen and platform signatures such as DocuSign are not accepted outside USCIS's own e-filing system; a scan or fax of a properly wet-signed original is. What changed is the consequence: a filing with a defective signature is improperly filed from the outset, there is no chance to correct it, and the fee can be retained on denial.

The same instinct runs through consulates and foreign registries. Documents crossing a border for official use are usually authenticated under the 1961 Apostille Convention, which has 130 contracting parties and replaces the old chain of consular legalisation with one certificate. The Convention has moved on — an e-Apostille cannot be refused for being electronic — but the underlying document must still satisfy whoever receives it, and many still expect notarised paper. Since an apostille certifies a notarial signature, the notarisation question comes first.

Why arguing about it is a losing move

There is a specific failure pattern here. Someone establishes, correctly, that ESIGN makes their electronic signature valid, then spends a fortnight explaining it to a bank's document-processing team — which has no authority to change the requirement and no interest in the statute. Meanwhile the closing date moves.

The asymmetry is worth stating plainly. Complying with an unnecessary ink request costs a printer, a pen and a courier. Not complying costs the transaction. Escalating is worth it only where the requirement is systematic and you can reach whoever owns the policy — and even then it is a procurement conversation, not a legal one.

If you have to produce ink

A narrow exception with a wide shadow

The statutory list is short: wills and the documents around death, the parts of family law a court controls, most of the UCC outside the sale of goods, court filings, a named set of notices — plus whatever your state added to its UETA. If your document is not on it, the law is not the reason someone wants it printed.

The shadow is wider than the list because institutions are slow and paper is a habit, and that gap is not something to discover on the day of a closing. At the start of any transaction involving a registry, a lender, a consulate or a court, ask what format each accepts. The answer takes one email, is rarely what anyone assumed, and sets the schedule for everything after it.
