North Dakota Auto Repair Law

Educational summary only – not legal advice.

North Dakota does not have a comprehensive auto-repair consumer statute. Auto repair transactions are governed primarily by general contract law, general consumer protection law, and mechanic’s lien statutes. Many consumer protections common in other states are not explicitly required by statute.

1. Written Estimates

State law does not require a written estimate before repairs begin.

North Dakota statutes do not mandate written, oral, or itemized estimates for automobile repairs. If an estimate is provided, it becomes part of the contract between the parties.

State law does not specify written estimate requirements; general contract and consumer protection statutes apply.

2. Authorization to Repair

North Dakota law does not require written authorization to perform repairs.

There is no statute requiring a signed authorization form, specific disclosures, or diagnostic approval language. Authorization may be written, verbal, or implied.

State law does not specify authorization form requirements; general contract law applies.

3. Over-Estimate Approval Rules

North Dakota law does not set dollar or percentage thresholds for exceeding an estimate.

There are no statutory limits such as “$50 over” or “20% over” an estimate. Exceeding an estimate may still violate consumer protection law if deceptive.

State law does not specify over-estimate approval rules; deceptive practices are prohibited under general consumer law.

4. Disclosure Timing

North Dakota law does not specify when cost disclosures must be made.

There is no requirement that costs be disclosed before work begins or that price changes be disclosed mid-repair.

State law does not specify disclosure timing; general contract principles apply.

5. Parts Return Rules

North Dakota law does not require return of replaced parts.

There is no statute requiring automatic return of parts or return upon request.

State law does not specify parts return requirements; general consumer protection law applies.

6. Record Retention

North Dakota law does not specify record-retention requirements for auto repair shops.

There are no statutory timelines for retaining estimates, invoices, or authorizations.

State law does not specify record-retention durations.

7. Mechanic’s / Repairman’s Lien Law

North Dakota provides strong lien rights to repair shops.

Key Provisions

·       Repair shops have a possessory lien on vehicles for reasonable repair and storage charges.

·       Storage charges begin 15 days after the owner is asked to take possession.

Large Repair Notice Requirement

If repairs exceed $6,000 or 30% of the vehicle’s value, and the shop wants lien priority over recorded lienholders, the shop must notify lienholders by certified mail, including:

·       Description of repairs

·       Estimated repair cost

·       Estimated post-repair value

8. Enforcement & Penalties

There are no automatic statutory penalties for failing to provide estimates, authorizations, or parts return.

Enforcement occurs through: – Contract disputes – Unfair or Deceptive Trade Practices law – Civil litigation

Potential consequences include reduced or voided charges and Attorney General enforcement.

What This Means for Consumers

·       Always request written estimates and written authorization

·       Do not rely on assumed statutory protections

·       Disputes depend on what was agreed, not on repair-specific statutes

What This Means for Repair Shops

·       Broad flexibility, but increased litigation risk

·       Written documentation is critical

·       Lien rights are strong, but notice requirements must be followed

Bottom Line

North Dakota auto repair law is minimalist. Documentation—not statute—is the primary protection for both consumers and repair shops.
