Indiana Auto Repair Law

Educational summary only – not legal advice.

Indiana does not have a standalone Motor Vehicle Repair Act. Instead, auto repair practices are governed primarily by Indiana’s Deceptive Consumer Sales Act (DCSA) and general contract law. This document decodes what the statutes actually require in day‑to‑day repair situations.

1. Estimates & Dollar Thresholds

Written Estimates

State law does not require a written estimate before work begins.

However, estimates become legally significant once given.

Over‑Estimate Rule (Critical)

A repair shop commits a deceptive act if all of the following occur: – The final price exceeds the estimate by 10% or more, and – The total repair cost is over $750, and – The shop did not obtain written authorization to exceed the estimate.

This is the only explicit dollar threshold in Indiana auto repair law.

2. Authorization Requirements

Authorization to Perform Repairs

·       Repairs must be authorized.

·       Performing repairs the shop knows (or should know) are unauthorized is a deceptive act.

Form of Authorization

State law does not specify a required authorization form. – Authorization may be verbal or written. – Written authorization is strongly recommended, especially for jobs over $750.

3. Disclosure Timing

·       No statutory requirement that estimates or labor rates be disclosed before work begins.

·       Once an estimate is given, it cannot be exceeded beyond the 10% / $750 threshold without written approval.

Where timing is disputed, general consumer protection and contract law apply.

4. Parts Return & Inspection Rules

Replaced Parts

·       Shops must retain replaced parts for at least 72 hours after notifying the customer that repairs are complete.

·       Customers must request inspection within that 72‑hour window.

Automatic Return?

State law does not require automatic return of replaced parts. Inspection is on request only.

Disposing of parts earlier than allowed is a deceptive act.

5. Record Retention

State law does not specify record retention periods for independent repair shops.

·       No statutory minimum for keeping estimates, invoices, or authorizations.

·       General business record‑keeping principles apply.

(Dealers performing warranty work have additional documentation obligations.)

6. Enforcement & Consequences

Consumer Remedies Under the DCSA

If a repair shop violates the law, a consumer may recover: – Actual damages – Statutory minimum damages per violation – Treble damages for willful violations – Attorney’s fees

Consumers usually must send a written demand notice before filing suit.

Effect on Charges

·       Unauthorized or deceptively increased charges may be unenforceable.

·       Shops risk civil liability even if repairs were mechanically successful.

7. Mechanic’s Lien (Payment Disputes)

·       Indiana allows repair shops to assert a mechanic’s lien for unpaid repairs or storage.

·       Strict statutory notice and sale procedures must be followed.

·       Improper lien enforcement can expose shops to liability.

Executive Summary

What This Means for Consumers

·       Always request a written estimate and keep a copy.

·       If your bill exceeds the estimate by 10% or more on a job over $750, the shop must have your written approval.

·       You have the right to inspect replaced parts within 72 hours after being notified repairs are complete.

·       Unauthorized repairs or premature disposal of parts may violate Indiana consumer protection law.

What This Means for Repair Shops

·       Indiana law is permissive, but documentation protects you.

·       Always get written authorization before exceeding estimates on jobs over $750.

·       Retain replaced parts for at least 72 hours after notifying the customer.

·       Clear estimates, signed repair orders, and approval logs are your best defense against DCSA claims.

Bottom Line: Indiana auto repair law is short on technical rules but strict on deception. If a dispute looks unfair or misleading, the DCSA is likely the enforcement tool.
