Letter Of Explanations Form
Use a Letter Of Explanations template to make your document workflow more streamlined.
What a letter of explanations does
A Letter Of Explanations Form is a written statement that clarifies unusual facts, missing records, or circumstances surrounding a U.S. business, financial, housing, or administrative matter. It gives a reviewer the relevant context, identifies supporting documents, and records the writer’s explanation for later reference. The letter is not a universal government form with one required layout, so its fields and filing deadline depend on the recipient’s instructions. With signNow, the writer can upload the letter, place fields, request a signature, and preserve the completed document with its audit trail.
Who uses explanation letters
Mortgage applicants
Mortgage applicants use explanation letters to clarify employment gaps, deposits, credit events, or missing records requested during underwriting.
Business owners
Business owners use them to document unusual transactions, explain incomplete files, or provide context to lenders, auditors, and counterparties.
Business types using explanation letters
Explanation letters help organizations document context when a reviewer needs more than the underlying record alone.
Solo mortgage advisers use explanation letters to organize borrower context, attach supporting records, and send one signed explanation for underwriting review without reconstructing the file manually. Regional accounting firms use them to document unusual client transactions, obtain an acknowledgment, and retain a traceable explanation alongside invoices or tax-supporting records. Enterprise compliance teams use controlled templates, signer authentication, and audit trails when explanations move between departments, regulated partners, or external reviewers.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.

Privacy pitfalls in explanation letters
Including unnecessary Social Security numbers, account details, or health information can expose personal data beyond the reviewer’s actual need. A missing consent statement can weaken electronic delivery when a consumer must receive records under the ESIGN Act. Sharing a signing link without access controls can expose an explanation letter to an unintended recipient. A vague explanation without dates, supporting records, or a clear signer identity may not resolve the reviewer’s question.

Legal standing of explanation letters
A signed Letter Of Explanations Form may provide evidence of the writer’s explanation, intent, and document history when executed under the ESIGN Act, UETA, or New York ESRA. Electronic records do not replace wills, court orders, official court filings, or family law decrees excluded by 15 U.S.C. §7003.

When other legal rules apply

Wills and codicils
Court documents
Real-estate deeds
Troubleshooting explanation letters
Resolve field, signer, consent, compliance, and document-scope issues before relying on a signed Letter Of Explanations Form.
Upload the original PDF again and check whether fields are selectable. signNow can auto-detect fillable fields, but a scanned image may require manually placed text, date, or signature fields before sending.
Confirm the signer’s email address and resend the invitation from the document workspace. If the signer still cannot open it, use a signNow signing link or request a new invitation rather than editing the completed record.
Business includes legally binding eSignatures, templates, and audit trails at $8/user/month when billed annually. It includes 100 signature invites per user annually, with overage fees, so confirm volume before sending repeatedly.
For consumer-facing explanation letters, apply the ESIGN Act’s consent requirements under 15 U.S.C. §7001(c): disclose electronic-record rights and confirm access to the electronic format before relying on electronic delivery.
signNow lists HIPAA compliance with a BAA requirement. Use that configuration only when the explanation letter contains protected health information and the responsible organization has executed the required BAA.
An explanation letter does not override ESIGN exceptions. Wills, codicils, testamentary trusts, court orders, official court filings, and family law decrees may require another process under 15 U.S.C. §7003.
