Get Started

Most business documents can be signed electronically under the federal ESIGN Act. A specific set still can’t: wills and estate documents, certain court filings, notices of foreclosure or eviction, insurance cancellation notices, and negotiable instruments like promissory notes. Legal, lending, and government records teams run into this most often.

What “Wet Signature” Actually Means

A wet signature is a signature made by hand, in pen, on a physical document: the opposite of a typed name, a click-to-sign checkbox, or a cryptographic e-signature. The term exists because, for the last two decades, it hasn’t been the default. It’s the exception you now have to name.

That shift happened fast. The federal ESIGN Act passed in 2000 and gave electronic signatures the same legal weight as ink ones for most contracts. Twenty-some years later, most businesses sign everything from NDAs to six-figure vendor contracts with a few clicks. So when someone flags that certain industries still can’t do that, the usual reaction on a records team is surprise: wait, which ones, and why?

The ESIGN Act carves out a specific, short list of document types where an electronic signature doesn’t automatically count, no matter how the underlying deal feels about it. The two categories that show up most for a records team: wills, codicils, and testamentary trusts, and anything filed with a court.

This isn’t an oversight in the law. Congress wrote 15 U.S.C. § 7003 to exclude the specific situations where a click doesn’t carry enough legal weight, or where a state’s existing rules (probate law, landlord-tenant law) already predate e-signatures by decades. The excluded categories are:

  • Wills, codicils, and testamentary trusts, governed entirely by state law
  • Family law matters: adoption, divorce, and similar proceedings
  • Most of the Uniform Commercial Code, except Article 2 (sales) and Article 2A (leases), which means negotiable instruments and most secured transactions fall outside ESIGN
  • Court orders, notices, and official court documents, including briefs and pleadings
  • Notices of utility service cancellation or termination
  • Notices of default, acceleration, repossession, foreclosure, or eviction tied to a primary residence
  • Notices of health or life insurance cancellation
  • Product recall notices involving a health or safety risk
  • Documents required to accompany the transport of hazardous materials

Every state has adopted a version of the same framework, mostly through the Uniform Electronic Transactions Act, which draws nearly identical lines. A few states run their own statute instead. New York uses the Electronic Signatures and Records Act rather than UETA, though the practical effect on most of these exceptions is similar.

The Documents and Industries Where Original Signatures Still Rule

In practice, four categories come up over and over: estate documents, litigation records, high-stakes consumer notices, and negotiable financial instruments.

Wills and estate planning. This is the cleanest case. Nearly every state still requires a will to be signed in ink, in front of witnesses, sometimes notarized on top of that. A small, growing number of states now allow electronic wills under versions of the Uniform Electronic Wills Act, but it’s still the exception, and the rules differ enough state to state that most estate attorneys default to paper anyway. Every signed original then has to survive the client, sometimes for decades, before anyone needs it again.

Court filings and litigation records. Pleadings, motions, and anything a court requires “executed in connection with court proceedings” sit outside ESIGN by name. Litigation adds a second layer on top: once a document becomes evidence, or falls under a preservation duty, it needs a demonstrable chain of custody, not just a valid signature.

Notices that protect someone’s home, utilities, or coverage. This one surprises people. The exceptions here, foreclosure, eviction, utility shutoff, insurance cancellation, aren’t really about signatures at all. They exist so nobody loses a house or a health plan over a notice that got buried in a spam folder. Congress built consumer protection directly into the exceptions list.

Negotiable instruments. A promissory note is a good example: it’s a UCC Article 3 instrument, which ESIGN doesn’t touch. Lenders who want to convert paper notes into electronic ones need a purpose-built registry system for that, not just an e-signature tool. Until that’s in place, the paper note is the only enforceable one, and it has to be tracked as a single controllable original rather than just filed away.

Here’s the part that trips people up if they only skim an ESIGN Act summary online: this list isn’t really about which documents are “important.” Plenty of e-signed contracts carry more money and more risk than a routine will. It’s about which situations lawmakers decided needed a harder-to-fake, harder-to-rush signal, or where a state’s existing rulebook, probate law, the UCC, landlord-tenant law, simply predates electronic signatures and nobody’s rewritten it yet.

Law firms end up holding more of these permanently-paper documents than almost any other kind of business, because the exceptions cluster around exactly what they handle: wills, court filings, and the negotiable instruments tied to a case or a closing.

That’s a big part of why legal remains one of the strongest verticals for physical document storage, even as firms digitize everything else. A firm can move its billing, its email, and most of its client files to the cloud and still end up as the long-term custodian of a signed will, an executed settlement agreement, or a client’s original promissory note, because nothing about digitizing the rest of the practice changes what the law requires for those specific documents. The access delays firms feel when a partner needs a twelve-year-old original for a probate dispute are a direct result of this: the document has to exist somewhere on paper, and somebody has to be able to find it fast.

What Proper Storage Actually Looks Like for These Originals

A wet-signature original needs three things a filing cabinet doesn’t reliably give it: a documented chain of custody, fast and controlled retrieval, and protection from the slow physical decay nobody notices until the document is already damaged.

The chain-of-custody part matters more than it sounds like it should. If a promissory note or a will ever gets challenged, a valid signature alone doesn’t settle it; someone has to be able to prove the document wasn’t altered or swapped since the day it was signed. That’s what a barcoded chain-of-custody system is built to answer: every pickup, storage location, and retrieval logged against a specific original, not just filed and hoped for.

The practical move most firms land on is a hybrid, not an all-or-nothing choice. The wet-signature original goes into secure, climate-controlled storage where it won’t degrade and can be tracked by barcode. A scanned working copy handles daily business: pulling up a contract during a call, sending a copy to opposing counsel, attaching it to a filing. Nobody needs the ink version day to day; they just need to know exactly where it is and how fast they can get it back when it counts. A self-service retrieval system, like GRM’s eAccess portal, exists for that last part: requesting a specific box or file without waiting on a phone call, with same-day or next-day delivery depending on the service level.

One more thing worth saying plainly: none of this is an argument for destroying anything early. A wet-signature original that’s no longer legally required to stay on hand often still sits through the same retention schedule as its digital counterparts. Storage stays the default. A documented review, not a calendar reminder, is what decides when, or if, that changes.

Frequently Asked Questions

Are electronic signatures legally valid in the United States?

Yes, for most contracts. The federal ESIGN Act (2000) and the state-level Uniform Electronic Transactions Act give e-signatures the same legal standing as ink signatures for the large majority of business documents, as long as both parties agree to sign electronically.

What documents cannot be signed electronically?

Wills, codicils, and testamentary trusts; most documents governed by the Uniform Commercial Code outside of sales and lease contracts, including negotiable instruments like promissory notes; court orders and official court filings; and specific consumer notices covering utility cancellation, foreclosure, eviction, and health or life insurance cancellation.

Do real estate documents require a wet signature?

Most real estate contracts can be signed electronically under the ESIGN Act. The exceptions tend to show up around the edges: notarization and county recording requirements still vary by state, and any promissory note involved in the financing is a separate UCC instrument that typically needs an original signature or a purpose-built electronic note system.

Can a will be signed electronically?

In most states, no. A small number of states have adopted versions of the Uniform Electronic Wills Act, but the requirements differ enough between them that most estate planning attorneys still default to a signed, witnessed paper original.

How should a business store original wet-signature documents?

In a secure, climate-controlled facility with a documented chain of custody for every pickup and retrieval, indexed by barcode rather than a manual log. Pairing that with a scanned working copy lets a team handle daily business off the digital version while the original stays protected and retrievable for the rare moment it’s actually needed.
