Borrowers periodically ask whether commercial loan documents can be executed electronically. While electronic signatures are legally recognized, their use in commercial lending remains institution-specific. Many lenders continue to require traditional “wet-ink” signatures for certain core documents, particularly promissory notes and mortgages, based on enforcement, operational, and recording considerations.

As a general matter, electronic signatures are enforceable under the federal Electronic Signatures in Global and National Commerce Act (E-SIGN) and the Uniform Electronic Transactions Act (UETA), adopted in most states. A contract or signature may not be denied legal effect solely because it is in electronic form, provided the parties intend to sign electronically and proper records are retained.

A few documents of particular note:

  • For ancillary loan documents, electronic execution can present limited legal risk if reliable authentication and record retention procedures are in place. Greater complexity arises with promissory notes. Because a note is typically a negotiable instrument governed by Article 3 of the UCC, enforcement traditionally depends on possession of the original wet-ink note. If the original cannot be produced, enforcement may require additional steps, such as a lost note affidavit.
  • Electronic promissory notes (eNotes) are permitted but must qualify as “transferable records” under E-SIGN. In lieu of physical possession, the lender must demonstrate “control” of a single authoritative copy. This is typically accomplished through a secure electronic vault (eVault), which serves as a digital lockbox—maintaining the authoritative copy, preventing alteration, and tracking transfers of control. Lenders without compliant vaulting infrastructure may determine that wet-ink notes better align with their enforcement and secondary market practices.
  • Mortgages and deeds of trust present additional considerations. These instruments must generally be notarized and recorded to perfect a lender’s lien. While many states now authorize remote online notarization (RON) and electronic notarization, the rules vary by jurisdiction. Compliance requires not only a valid electronic signature, but also adherence to state-specific notarial procedures, identity verification standards, and approved technology platforms. In addition, county recording offices differ in their acceptance of electronically executed and electronically notarized documents. Some permit full e-recording; others continue to require paper submissions.

In short, although electronic signatures are legally viable, their use in commercial lending involves more than simple execution mechanics. Lenders should evaluate enforceability, vaulting capabilities, notarization requirements, and local recording practices before modifying established closing procedures.

As borrowers continue to request greater efficiency in closings, lenders are weighing how and when electronic execution makes sense within their existing credit, enforcement, and operational frameworks. There is no one-size-fits-all approach. Careful evaluation of note control, vaulting systems, notarization compliance, and local recording practices is essential before changing documentation procedures.
