Indiana Automobile Purchase Agreement Overview

An automobile purchase agreement in Indiana is a pre-sale contract that establishes all terms and conditions before the vehicle transaction closes. This is different from a bill of sale, which simply records a completed sale. The purchase agreement protects both parties by defining the price, financing, inspection contingencies, warranty terms, and conditions for closing.

Indiana's flat 7% sales tax applies to all vehicle purchases. Indiana's Lemon Law covers new vehicles within 18 months or 18,000 miles of delivery.

Indiana Automobile Purchase Requirements

Title transfer must be completed within 31 days.

Emissions testing is required only in Lake and Porter counties (northwest Indiana).

Purchase Agreement vs. Bill of Sale

An automobile purchase agreement is signed BEFORE the sale closes and establishes conditions (financing approval, inspection results, lien payoff). A bill of sale is signed AFTER/AT closing as a receipt. For complex transactions involving financing, trade-ins, or lien payoffs, a purchase agreement provides far more protection than a bill of sale alone.

What to Include in Your Indiana Automobile Purchase Agreement

  • Vehicle Details: Year, make, model, VIN, mileage, color, and condition
  • Purchase Price & Payment: Agreed price, payment method, financing terms, and deposit amount
  • Trade-In: Trade-in vehicle details, agreed trade-in value, and lien payoff (if applicable)
  • Inspection Contingency: Buyer's right to have the vehicle inspected by a mechanic before closing
  • Warranty / As-Is: Whether any warranty applies or the vehicle is sold as-is
  • Emissions Compliance: Required in Lake and Porter counties only — seller must provide valid emissions certificate

Key Provisions for Indiana

Financing Terms

If the buyer is financing the purchase, the agreement should include a financing contingency allowing the buyer to cancel if they cannot obtain financing within a specified period. Include the anticipated loan amount, interest rate, and term.

Lemon Law Protection

New vehicles (within 18 months or 18K miles). Indiana's lemon law covers only new vehicles. For used vehicle purchases, include thorough inspection contingencies in your agreement.

VIN Verification & History

The agreement should require the seller to verify that the VIN matches all documents, disclose whether the vehicle has a salvage or rebuilt title, and allow the buyer to obtain a vehicle history report. This protects against odometer fraud, undisclosed accidents, and title washing.

Lien Payoff Process

If the seller has an outstanding loan on the vehicle, the agreement must address how the lien will be satisfied. Typically, the buyer's payment goes through escrow to pay off the lien first, with the remainder going to the seller. The seller must deliver a clean title within a specified timeframe.
