What is an Addendum Request Form?

An addendum is a written amendment that modifies an existing agreement while leaving the original contract intact. It must identify the original agreement, specify exact changes, include an effective date, and be signed by authorized parties to be enforceable.

Can an addendum be signed electronically?

Yes. Under the ESIGN Act (15 U.S.C. ch. 96) and UETA (1999), electronic signatures satisfy legal signature requirements for most transactions provided the e-signature meets the intent, consent, attribution, and retention criteria.

When is notarization required?

Notarization is usually not required for simple contract amendments but is often required for documents recorded with public offices or for specific statutory instruments. Check local recording and real estate rules before execution.

What if party names differ from the original contract?

Use exact legal names as used in the original agreement or clearly indicate a legal name change with supporting documentation. Mismatched names can cause enforceability and title issues.

How do I revoke or cancel an addendum?

Revocation requires a new written amendment or mutual agreement that expressly rescinds the earlier addendum; unilateral cancellation is effective only if allowed by the contract or by mutual consent.

How should executed addenda be stored?

Store signed originals (or high-fidelity electronic copies with audit trails) in a controlled repository. Retain according to applicable federal and industry retention rules, and ensure reproducibility for audits or litigation.

What an Addendum Request Form Is

An Addendum Request Form is a written amendment used to change, clarify, or add terms to an existing agreement without replacing the original contract. It references the original document, describes specific modifications, and records the parties' mutual consent. Commonly used for contracts, leases, purchase agreements, and employment terms, the form preserves continuity by linking to the original agreement and establishing the effective date and scope of the change to avoid ambiguity in enforcement and recordkeeping.

Why Use an Addendum Request Form

An addendum formalizes agreed changes and reduces disputes by creating a clear, dated amendment that references the original contract. Properly executed, an addendum preserves enforceability under ESIGN (15 U.S.C. ch. 96) and UETA (1999) when electronic execution requirements are met.

Who Typically Prepares and Signs Addenda

Common users span legal, operations, and transactional roles across industries.

Contract managers and corporate counsel who track and approve contractual changes during negotiations or project updates.
Real estate brokers, title officers, and property managers issuing post-agreement updates to leases or purchase contracts.
HR and hiring managers updating offer terms, compensation schedules, or employment conditions during onboarding or renegotiation.

Tailor the form to the role: corporate records need board approval workflows; field teams need quick mobile signing.

Core Elements of a Professional Addendum Request Form

A well-structured addendum is concise, references the original agreement, identifies parties, and explains each change with an effective date and signature blocks to confirm mutual acceptance.

Addendum Title

A short descriptive title that identifies the original agreement and addendum purpose, so records are easy to locate and index.

Original Agreement

Clear reference to the original contract including title, date, and parties so the amendment links precisely to the correct document.

Amendment Details

Line-by-line description of changes: insertions, deletions, or replacements. Use numbered paragraphs to map each modification to the original text.

Effective Date

Explicit effective date or triggering conditions for the amendment to establish when rights and obligations change.

Consideration

If applicable, a brief statement of consideration or mutual exchange confirming the amendment is supported by value or mutual obligation.

Signature Blocks

Signature lines for all parties, dates, printed names, and authority titles to confirm who is authorized to bind each party.

Essential Fields Required on the Form

Addendum Title: Short descriptive name

Referenced Contract: Original agreement date

Parties: Full legal names

Effective Date: MM/DD/YYYY
