Can an engagement letter be signed electronically?

Yes. Electronic signatures are enforceable under the federal ESIGN Act (15 U.S.C. ch. 96) and UETA in most jurisdictions. Ensure the signer’s intent, consent to electronic records, attribution, and reliable retention to meet the four-part validity test.

Do engagement letters need notarization?

Typically no. Engagement letters are contractual; notarization is rarely required. If a jurisdiction or specific corporate process demands notarization or a witness, include that step before relying on the document for regulatory submissions.

Who must sign to make the letter binding?

An authorized company officer (e.g., CEO, CFO, or board chair) must sign for the client. Verify authority through corporate resolutions or board minutes to avoid disputes over signer capacity.

How long must signed letters be retained?

Retention depends on regulatory context: retain audit files and engagement letters per SOX (7 years, 15 U.S.C. §7245) and IRS minima (3 years, IRC §6501(a)), and longer for industry-specific rules.

What authentication level is recommended?

At minimum, use email verification with an audit trail. For higher-risk clients or regulated industries, use stronger methods such as SMS codes, knowledge-based authentication, or SSO.

Can I amend the letter after signing?

Yes, but amendments should be in writing, signed by both parties, and reference the original engagement letter; document any changes to scope, fees, or timing explicitly.

What a Financial Audit Engagement Letter Is and When It’s Used

A Financial Audit Engagement Letter is a written agreement between an audit firm and a client that defines the scope, objectives, responsibilities, and timing of a financial statement audit. It documents the auditor’s deliverables, management’s responsibilities for records and internal controls, reporting deliverables, limitations of the engagement, and fee arrangements. For external financial audits, the engagement letter establishes professional standards to be followed and provides evidence of mutual understanding before fieldwork begins. Many regulators and auditing standards bodies expect a signed engagement letter on file before substantive audit procedures commence.

Why a Clear Engagement Letter Matters for Audits

A precise engagement letter reduces misunderstandings, clarifies deliverables, limits professional liability, and documents the terms auditors and management agreed to before work starts; it serves both compliance and project-management functions.

Who Prepares and Signs a Financial Audit Engagement Letter

Ensure signatory authority is documented and consistent with corporate governance or board resolutions before signing.

Audit firm partner or engagement manager prepares the draft and confirms scope with the client before circulation for signature.
Chief financial officer, controller, or authorized company officer signs on behalf of the client to accept responsibilities and confirm representations.
Board audit committee chair or governance designee may sign for public companies or entity-level engagements requiring formal board acceptance.

Not documenting management representations or deliverable timelines, which complicates audit conclusions and reporting deadlines.
