If you die without a valid will while residing in the State of Idaho, you are said to have died "intestate." In order to determine who will receive your property if you die intestate, the State of Idaho has established a number of laws (known as "intestacy laws" or "laws of intestate succession.") The primary statutes comprising these intestacy laws, or laws of intestate succession, are set forth below. For a more complete list, see Idaho intestacy Laws | Intestate Succession statutes.
Any part of the estate of a decedent not effectively disposed of by his will passes to his heirs as prescribed in the following sections of this code.
The intestate share of the surviving spouse is as follows:

(2) If there is no surviving issue but the decedent is survived by a parent or parents, one-half (1/2) of the
(3) If there are surviving issue of the deceased spouse, one-half (1/2) of the intestate estate.
(b) As to community property:
(1) The one-half (1/2) of community property which belongs to the decedent passes to the surviving spouse.
The part of the intestate estate not passing to the surviving spouse under section 15-2-102 of this part, or the entire intestate estate if there is no surviving spouse, passes as follows:
(a) To the issue of the decedent; if they are all of the same degree of kinship to the decedent they take equally, but if of unequal degree, then those of more remote degree take by representation;
(b) If there is no surviving issue, to his parent or parents equally;
(c) If there is no surviving issue or parent, to the issue of the parents or either of them by representation;
(d) If there is no surviving issue, parent or issue of a parent, but the decedent is survived by one (1) or more grandparents or issue of grandparents, half of the estate passes to the paternal grandparents if both survive, or to the surviving paternal grandparent, or to the issue of the paternal grandparents if both are deceased, the issue taking equally if they are all of the same degree of kinship to the decedent, but if of unequal degree those of more remote degree take by representation; and the other half passes to the maternal relatives in the same manner; but if there be no surviving grandparent or issue of grandparents on either the paternal or the maternal side, the entire estate passes to the relatives on the other side in the same manner as the half.
