North Dakota Consumer Fraud Statute (§ 51-15-09)

North Dakota's Unlawful Sales or Advertising Practices chapter (N.D. Cent. Code ch. 51-15) — discretionary treble damages and mandatory attorney fees on a knowing violation, and how it backs up a lemon-law claim.

North Dakota’s consumer-protection statute is the Unlawful Sales or Advertising Practices chapter, N.D. Cent. Code ch. 51-15, with the private civil remedy at § 51-15-09. It backs up a lemon-law claim — especially where a dealer or manufacturer misrepresented or concealed something.

What it prohibits

Section 51-15-02 bars the use of any deceptive act or practice, fraud, false pretense, false promise, or misrepresentation, and the concealment, suppression, or omission of any material fact, in connection with the sale or advertisement of merchandise — including vehicles.

What you can recover

Under § 51-15-09, a person damaged by an unlawful practice may sue and recover:

  • Actual damages.
  • Treble damagesdiscretionary: the court may award up to three times actual damages where the defendant committed the practice knowingly.
  • Costs and reasonable attorney feesmandatory for a prevailing plaintiff where the violation was committed knowingly.

The “knowing” threshold is the hinge: prove the violation was knowing and you unlock both the treble multiplier and fee-shifting. See Consumer Fraud damages.

How it compares

North Dakota’s statute is a discretionary-treble UDAP — comparable to Montana’s and Rhode Island’s, and stronger than South Dakota’s (no treble at all). It is not an automatic-treble statute like Delaware’s or Hawaii’s. But the mandatory fee award on a knowing violation gives it real teeth.

The four-year clock

Consumer-fraud claims run on a four-year limitations period — far longer than the lemon law’s six-month deadline (§ 51-07-21). That makes the Consumer Fraud statute (and Magnuson-Moss) a critical fallback when the lemon-law clock has run.

How it pairs with the lemon law

  • The lemon law gives you the refund/replacement formula and the capped offset.
  • The Consumer Fraud statute adds treble damages and mandatory fees where the conduct was knowing — common in used-car deals involving concealed accident, hail, or flood history.
  • Magnuson-Moss adds a federal fee hook and a longer runway.

Bottom line

North Dakota’s Consumer Fraud statute can treble your damages and force the other side to pay your attorney on a knowing violation, and it runs four years — a vital backstop to the lemon law’s six-month deadline. Get a free case review.
