Are electronic letters legally valid?

Yes. Electronic signatures and records are generally legally binding under the ESIGN Act (15 U.S.C. ch. 96) and UETA where adopted; ensure the signature demonstrates intent, consent, attribution, and retention capability.

Do I need notarization or witnesses?

Not typically required for a commercial undertaking unless the beneficiary or a state law demands it; check local rules and the beneficiary's acceptance standards before executing.

How do I prove the signer had authority?

Attach a board resolution, power of attorney, or other delegation document. Including a reference to such authority in the signature block reduces later disputes.

Can I eSign if the counterparty insists on paper?

If a counterparty requires an original ink signature, provide a paper copy; otherwise ESIGN/UETA generally allow electronic records unless a statutory exception applies.

How do I revoke an undertaking?

Revocation depends on the letter's terms and applicable law; include explicit termination or revocation clauses and follow contractual notice requirements to avoid breach claims.

What authentication level is advisable?

Use at least email plus an audit trail for low-risk undertakings; use stronger methods (SMS OTP, KBA, or certified digital signatures) for high-value or regulatory-sensitive commitments.
