Can a Business IFS Letter be signed electronically?

Yes. Electronic signatures are valid under the ESIGN Act (15 U.S.C. §7001). UETA governs intrastate transactions in most states. Ensure intent, consent, attribution, and reliable record retention to meet the four-part ESIGN test.

When is notarization required?

Notarization depends on the letter's purpose and recipient requirements. Deeds and some affidavits always require a notary; other letters only when the recipient requests notarized proof of authority.

Who can sign on behalf of the company?

An authorized officer, director, or expressly delegated agent may sign. Verify internal authority via board resolution or delegation letters to avoid enforceability disputes.

What should I do if I entered incorrect information?

Do not alter a signed letter; prepare an amended letter clearly labeled as such, have the authorized signer execute it, and transmit with a short cover explaining the correction.

How long must I retain the signed letter?

Retain according to applicable rules: general tax records three years (IRC §6501(a)), HIPAA records six years (45 CFR §164.530(j)), and longer if industry rules or litigation holds apply.

Is a typed name sufficient as a signature?

A typed name can constitute an electronic signature if it meets ESIGN’s intent and attribution tests. For high-risk matters, prefer a full signatory or cryptographic signature and preserve the audit trail.
