Is an e-signature legally valid?

Yes. Electronic signatures meet federal ESIGN standards (15 U.S.C. ch. 96) and UETA requirements where adopted when intent, consent, attribution, and retention are satisfied. Be aware of statutory exceptions such as wills or certain court filings that may require wet signatures.

When is notarization required?

Notarization is required only when the recipient or the document’s intended legal effect demands it (for example, sworn affidavits). Remote online notarization (RON) is permitted in many states but verify state-specific rules and identity-proofing requirements before scheduling a session.

What supporting documents should I attach?

Attach the minimum set that proves the facts: relevant bank statements, invoices, payment confirmations, reconciliation spreadsheets, and, when appropriate, corporate resolutions or authorization letters to establish signer authority.

How long will review typically take?

Review times vary by recipient; banks often take 5–30 business days depending on complexity. Providing a clear chronology and labeled exhibits accelerates review and reduces the likelihood of follow-up requests.

What if the IRS or bank disputes the statement?

Provide additional supporting documentation promptly, preserve originals, and consider legal or tax counsel for formal responses. For tax exposures, incorrect reporting can trigger penalties under IRC §6721 or backup withholding rules, so escalate where necessary.

What a Business Account Letter of Explanation Is

A Business Account Letter of Explanation is a concise, written statement a company or authorized representative provides to clarify account activity, identity discrepancies, ownership details, or unusual transactions when opening or maintaining a business account or responding to inquiries from banks, processors, lenders, or regulators.
