(a) The surviving spouse of any decedent shall be entitled to receive and the executor or administrator shall pay to such spouse as soon as convenient, in the manner provided in this section, cash up to the amount of $7,500 out of the estate of the decedent, which payment shall be made in the order of preference of claims against the estate in § 2105 of this title, as amended. The foregoing provision shall not affect any other rights to which such spouse may be entitled, either under the will of the decedent or the intestacy laws of this State.
(b) The allowance to the surviving spouse of a decedent provided for in subsection (a) of this section shall be of no effect unless and until such spouse shall, within 9 months from the date of death or 6 months from the date of the granting of letters, testamentary or of administration, whichever shall be the shorter period, notify in writing the Register of Wills of the county wherein the letters were granted and the executor or administrator of such spouse's demand that a specific sum, not exceeding $7,500, be so set aside out of the proceeds of the estate of the decedent.
(c) The allowance provided for in subsection (a) of this section shall be considered to be a debt of the estate, and the executor or administrator may sell so much of the property of the decedent as will enable the executor or administrator to pay the allowance in the same manner as the executor or administrator may be enabled to do by law for the payment of other debts of the decedent or of the estate.
