If the decedent was domiciled in this state at the time of death the surviving spouse is entitled to receive, in addition to the homestead allowance, property of a value not exceeding seven thousand five hundred dollars ($7,500) in excess of any security interests therein in household furniture, automobiles, furnishings, appliances and personal effects. If there is no surviving spouse, children of the decedent are entitled jointly to the same value. If encumbered chattels are selected and if the value in excess of security interests, plus that of other exempt property, is less than seven thousand five hundred dollars ($7,500), or if there is not seven thousand five hundred dollars ($7,500) worth of exempt property in the estate, the spouse or children are entitled to other assets of the estate, if any, to the extent necessary to make up the seven thousand five hundred dollars ($7,500) value. Rights to exempt property and assets needed to make up a deficiency of exempt property have priority over all claims against the estate, except that the right to any assets to make up a deficiency of exempt property shall abate as necessary to permit prior payment of homestead allowance and family allowance. These rights are in addition to any benefit or share passing to the surviving spouse or children by the will of the decedent unless otherwise provided, by intestate succession, or by way of elective share.
