What to know about partial payment sales in California

Do not transfer the title until you have received full payment. Hold the title until all installment payments are made. Document the deposit amount, remaining balance, payment due date, and consequences of default in the bill of sale. Consider retaining the vehicle in addition to the title until final payment.

What to include in your bill of sale

  • Full legal names and addresses for both buyer and seller.
  • Car make, model, year, VIN, and current mileage.
  • Agreed sale price, payment method, and transaction date.
  • Any partial payment-specific disclosures required in California.

Seller guidance

Do not transfer the title until you have received full payment. Hold the title until all installment payments are made. Document the deposit amount, remaining balance, payment due date, and consequences of default in the bill of sale. Consider retaining the vehicle in addition to the title until final payment.

Buyer guidance

Get a signed receipt for your deposit and ensure the payment schedule is in writing. Clarify when you will receive the title and in what condition. Without a written agreement, a partial payment creates an ambiguous legal relationship and may give you limited recourse if the seller backs out or sells the vehicle to another buyer.

Legal considerations

Partial payment contracts are treated as installment sale agreements under UCC Article 2. Both parties have rights and obligations under the contract from the moment of deposit. The seller retains a security interest in the goods until payment is complete under UCC § 2-401. An installment sale may trigger TILA disclosure requirements if the buyer is paying interest. Each state may have its own requirements for documenting the security interest on the title.
