N.D. Cent. Code § 32-39-01: Voluntary service or partial payment not admissible

No voluntary service or partial payment of a claim, including a claim of medical malpractice, against any person based on alleged liability of that person for injury or damage arising out of any occurrence may be construed as an admission of fault or liability. Evidence of the service or payment is not admissible in any action for the purpose of determining the amount of any judgment or the liability of any person with respect to the occurrence.
