N.D. Cent. Code § 59-18-01.1: Presumption against trustee

A transaction between a trustee and the trust's beneficiary during the existence of the trust or while the influence acquired by the trustee remains by which the trustee obtains any advantage from the trust's beneficiary is presumed to be entered by the trust's beneficiary without sufficient consideration and under undue influence. This presumption is a rebuttable presumption.
