Section 30.1-04-01 - (2-101) Intestate estate1. Any part of a decedent's estate not effectively disposed of by will passes by intestate succession to the decedent's heirs as prescribed in this title, except as modified by the decedent's will.2. A decedent, by will, may expressly exclude or limit the right of an individual or class to succeed to property of the decedent passing by intestate succession. If that individual or a member of that class survives the decedent, the share of the decedent's intestate estate to which that individual or class would have succeeded passes as if that individual or each member of that class had disclaimed the intestate share.
