Installment Sale and Security Agreement Regarding Sale of Automobile

What this Installment Sale and Security Agreement is

The Installment Sale and Security Agreement Regarding Sale of Automobile is a written contract that records the sale of a motor vehicle where the buyer pays the purchase price over time and the seller retains a security interest until full payment. It sets the sale price, payment schedule, late charges, default remedies, and describes the vehicle by VIN, make, model, and year. The agreement also creates a lien under Article 9 of the Uniform Commercial Code until the buyer satisfies the debt and provides the parties with clear remedies and notice requirements for repossession and title transfer.

Why a formal agreement matters for installment vehicle sales

A clear written agreement protects both parties by documenting payment terms, collateral description, default remedies, and title transfer conditions, reducing disputes and supporting enforcement in court or through repossession.

  • File formats: PDF, DOCX supported

Ensure your chosen provider supports HIPAA/21 CFR or a BAA where applicable, preserves AES-256 at rest and TLS 1.2/1.3 in transit, and provides an auditable certificate of completion.

Real-world examples of how this agreement is used

Two short scenarios illustrate typical uses: private-party financing and dealer financing with securitization or title retention.

Private-Party Installment

A seller finances a buyer over 24 months with monthly payments and retains a security interest in the vehicle.

  • The buyer provides proof of insurance and makes electronic payments.
  • On final payment the seller files a lien release and transfers title with DMV forms to complete the sale and remove encumbrance.

Dealer Retail Installment

A dealership sells a vehicle and documents the finance contract with a third-party lender listed as secured party.

  • Payments flow to the lender and dealer retains conditional title paperwork.
  • The lender registers its lien via UCC-1 or DMV, and when the buyer completes payments the lender provides lien release for title transfer.
