Letter Of Agreement Between Two Parties Letter Form

Use a Letter Of Agreement Between Two Parties Sample Letter template to make your document workflow more streamlined.

What this agreement letter does

A Letter Of Agreement Between Two Parties Letter Form records the terms two parties accept for a defined business arrangement. It identifies the parties, describes the services or obligations, states payment and timing terms, addresses confidentiality or ownership, and provides signature lines. Each party should review the completed letter before signing. With signNow, upload the agreement, place or confirm fillable fields, send it to the named signers, and retain the signed document with its audit trail. ESIGN and applicable state law may recognize the electronic record when intent, consent, attribution, and reliable retention are established.

Who uses this agreement letter

Real estate

Real-estate professionals and property owners use agreement letters to document service scopes, referral terms, lease-related arrangements, or transaction responsibilities before formal closing documents.

Business teams

Legal, healthcare, construction, and finance teams use two-party letters for defined engagements, approvals, project obligations, and service arrangements requiring review and signatures.

Legal standing for business agreements

A signed Letter Of Agreement Between Two Parties Letter Form can document mutual assent and help establish the parties’ agreed obligations. Under ESIGN, 15 U.S.C. ch. 96, and UETA in adopting jurisdictions, electronic signatures may carry the same legal effect as handwritten signatures when intent, consent, attribution, and record retention are demonstrated. Wills, court orders, and certain family law documents remain excluded.

Why teams look for DocuSign alternatives

Challenges when preparing the agreement letter

  • Unclear party names or signing authority can make it difficult to prove which individuals accepted the agreement for each organization.
  • Broad descriptions of services, payment, or delivery dates may leave the parties disputing what performance the letter actually required.
  • Missing amendment procedures can create uncertainty when the parties later change scope, pricing, deadlines, or responsibilities.
  • A completed letter without an accessible audit trail may provide weaker evidence about signer identity, intent, and document integrity.

Best practices for agreement letters

Accurate party details, complete commercial terms, controlled signing, and organized records make this agreement letter easier to administer and defend.

Identify parties and signing authority

Name each party exactly as represented in the underlying business records, identify each signer’s role, and confirm that the signer has authority to bind the organization. Include addresses or notice details when the agreement requires formal communications between the parties.

State obligations and payment terms

Describe the deliverables, acceptance criteria, payment amount, invoicing schedule, start date, end date, and termination rights directly in the letter. Avoid relying on oral promises or undefined terms that could make performance obligations difficult to interpret later.

Assign and review every field

Assign every signature, date, initials, and acknowledgment field to the correct party before sending. Ask each signer to review the complete letter, preserve consent evidence, and avoid altering the agreement after a signature has been completed.

Archive the signed record securely

Export the completed agreement and audit trail, then store them in a restricted repository with a documented retention policy. Retention depends on the transaction and industry; state law or a contract may require longer storage than a general business policy.

Agreement letter processing stages

The completion time depends on document accuracy, signer availability, and any review or notarization requirement attached to the transaction.

Confirm parties, scope, payment, dates, signatures, and required attachments.

Send assigned fields through signNow email delivery or a signing link.

Troubleshooting agreement-letter workflows

Resolve the issue by checking the document fields, signer assignments, plan limits, consent record, and applicable U.S. requirements.

A missing signature field usually means the uploaded agreement was not prepared with a field at that location. In signNow, open the document editor, add the required signature, date, initials, and text fields, assign each field to the correct party, then resend the agreement. This preserves a clearer signing record.

Business includes legally binding eSignatures, templates, and audit trails at $8 per user per month when billed annually. It includes 100 signature invites per user per year, with overage fees. Business Premium adds bulk send and kiosk mode at $15 per user per month annually.

For a consumer-facing agreement, ESIGN requires disclosure of the right to receive paper records, access to the electronic format, and procedures for withdrawing consent under 15 U.S.C. §7001(c). Capture that consent before signing; signNow’s audit trail can preserve the related signing activity.

If a signer cannot open the agreement, confirm the recipient email address, resend the invitation, or provide a signNow signing link. The signer may review and sign from a supported browser or mobile app without changing the underlying agreement fields or signer assignments.

A signed agreement does not replace notarization when state law requires notarization for the specific transaction. For example, real-estate deeds generally require a notary acknowledgment in all 50 states. Check the applicable state Secretary of State or recording office before relying on electronic signing alone.

If your organization handles protected health information in the agreement workflow, HIPAA compliance requires a business associate agreement with signNow. The HIPAA retention rule requires six years from creation or the last effective date under 45 CFR §164.530(j).
