Can the agreement be e‑signed?

Yes. Under the ESIGN Act and state e‑signature laws, electronic signatures are generally enforceable if intent, consent, attribution, and reliable record retention are present.

Is notarization required?

Not usually required for donor agreements, but some states or institutional policies recommend notarization for added evidentiary weight or where real property or other formalities are involved.

How do I correct a signed error?

Prepare a short corrective amendment signed by the same parties or execute a mutually agreed replacement agreement; document the change and retain both versions.

What if a donor revokes the gift?

Review termination and refund clauses in the supplemental and original agreements. If the agreement lacks revocation terms, consult legal counsel for obligated funds.

Who must sign on behalf of the organization?

An authorized officer with delegated gift acceptance authority should sign; record the officer’s title and evidence of delegation in governance documents.

How should executed agreements be stored?

Store tamper‑evident signed PDFs in a centralized records system with backups, role‑based access, and retention aligned with IRS and industry requirements.

What a Supplemental Financial Donor Agreement Is

A Supplemental Financial Donor Agreement documents additional or changed financial commitments between a donor and a recipient organization after an initial gift or grant agreement. It records the donor's intent, any restrictions or designated purposes, payment schedules, reporting requirements, and conditions for use of funds. The supplemental agreement clarifies expectations for stewardship, supports internal controls for finance and compliance, and creates an auditable record for donors, nonprofit finance teams, and auditors. Where permitted, electronic execution and storage under ESIGN and state UETA laws make remote completion practical and defensible.

Why a Supplemental Agreement Matters to Donors and Organizations

A clear supplemental agreement reduces ambiguity about donor intent, protects restricted funds, and documents reporting obligations for tax and audit purposes.

Who Typically Completes a Supplemental Financial Donor Agreement

Typical users include both donor representatives and organizational staff responsible for gift acceptance and finance.

Donor representatives and foundation program officers who specify restrictions, schedules, and recognition preferences.
Development and gift-processing teams responsible for receipting, accounting entries, and donor stewardship.
Finance, grants, or compliance officers who track restricted balances and required reporting.

Accurate completion ensures legal clarity and enables consistent financial controls across gift administration and audit processes.
