About this page

North Dakota rent late fee law

North Dakota's Century Code chapters on leasing real property (47-16) and on eviction (47-32) contain no late fee provision, so neither limits a late rent fee or gives a grace period.

Read in full for this check: North Dakota Century Code, chapter 47-16 (Leasing of Real Property) and chapter 47-32 (Eviction). Official source · checked .

Before you send the late rent notice: it is a reminder letter about overdue rent and a late charge, not an eviction notice. A notice to pay rent or quit is a separate document, and North Dakota has its own rules for it. Nothing on this page is legal advice.

What North Dakota law says about invoice interest

Interest for any legal indebtedness must be at the rate of six percent per annum unless a different rate not to exceed the rate specified in section 47-14-09 is contracted for in writing. Unless otherwise agreed by the parties in writing, all contracts must bear the same rate of interest after maturity as they bear before maturity.
— N.D.C.C. § 47-14-05 (Legal rate of interest - Interest after maturity). Read it at the official source · row verified 2026-10-01.

Loans to a corp/LLC/partnership, and any deal over $35,000, are exempt. A sub-$35k debt owed by a sole prop stays under the floating cap (T-bill+5.5%, 7% floor; 9.293% as published for October 2026).
