Affidavit / determination of heirshipMaine has no affidavit-of-heirship statute for real estate. Heirs are determined by the Probate Court: a petition for formal probate of a will, or for adjudication of intestacy, asks the court to determine the heirs after notice and hearing, and a petition may request an order determining intestacy and heirs without appointing an administrator.
Who inherits without a willSurviving spouse: the entire estate if the deceased left no descendants or parents, or if all of the deceased's descendants are also the spouse's and the spouse has no other descendants. If no descendants but a parent survives, the spouse takes a set dollar amount plus 3/4 of the rest. If all descendants are shared but the spouse has other descendants, the spouse takes a set dollar amount plus 1/2 of the rest. If the deceased has descendants who are not the spouse's, the spouse takes 1/2. For deaths in 2026 the set amounts are $394,000 and $131,300 (the statute's $300,000 and $100,000, adjusted yearly for inflation). Whatever does not pass to the spouse goes to descendants; if none, to parents; if none, to brothers and sisters and their descendants; then to grandparents' families.
