§ 34-77-155

(a) Upon the death of a spouse, one-half of the aggregate value of the community property owned by the spouses and by any community property trust established by the spouses reflects the share of the surviving spouse and the other one-half reflects the share of the decedent. (b) Upon the death of a spouse, the deceased spouse's personal representative and the trustee of a community property trust each have the power to distribute community property in divided or undivided interests and to adjust resulting differences in valuation. A distribution of community property in kind may be made on the basis of a non pro rata division of the aggregate value of the community property, on the basis of a pro rata division of each individual item or asset of community property, or by using both methods. (c) Notwithstanding (a) and (b) of this section, spouses may agree in writing to divide their community property on the basis of a non pro rata division of the aggregate value of the community property or on the basis of a pro rata division of each individual item or asset of community property, or by using both methods.
