Where a testator dies leaving a surviving spouse and a person under the age of 18 entitled to claim legitim, and provision is made in his will or other testamentary document for a disposition to his spouse which, if it could take effect, would leave insufficient property in the estate to satisfy the entitlement of that person in respect of legitim, the following provisions of this section shall apply.

Subject to subsections (3) and (4) below, tax shall be charged at the testator’s death as if the disposition to the spouse did not include any amount in respect of legitim, but if within the period mentioned in subsection (6) below the person or persons concerned renounce their claim to legitim, tax shall be repaid to the estate calculated on the basis that the disposition to the spouse did include the amount renounced.

The executors or judicial factor of the testator may, in accordance with the provisions of this section, elect that subsection (2) above shall not apply but that subsection (4) below shall apply.

Tax shall be charged at the testator’s death as if the disposition to the spouse had taken effect, but where the person or persons concerned claim legitim within the period mentioned in subsection (6) below, tax shall be charged on the amount so claimed calculated on the basis that the legitim fund had been paid out in full at the testator’s death (excluding any part of the fund renounced before any claim has been made) and the tax chargeable thereon had been apportioned rateably among the persons entitled to claim legitim (excluding any who have renounced as aforesaid).

Where the executors or judicial factor of the testator decide to make an election under subsection (3) above they shall give notice in writing of that election to the Board within two years from the date of death of the testator or such longer period as the Board may permit.

For the purposes of subsections (2) and (4) above, a person shall be treated as having claimed legitim unless he has renounced his claim before attaining the age of 18 or he renounces his claim within two years of his attaining that age or such longer period as the Board may permit.

Where a person dies before attaining the age of 18 or before making a renunciation under subsection (6) above the provisions of this section shall apply in relation to that person’s executors or judicial factor as they would have applied in relation to that person if that person had attained the age of 18 with the substitution of the date of death of that person for the date on which a person attained that age; but where the executors or factor renounce a claim to legitim in respect of a person the amount renounced shall not be treated as part of that person’s estate.

Where subsection (2) above applies in relation to any estate, then notwithstanding anything in section 241 below the Board may repay tax under that subsection without limit of time.

Where subsection (4) above applies in relation to any estate, then notwithstanding anything in section 239 below a certificate of discharge may be given under that section in respect of the whole estate, and notwithstanding anything in section 240 below the giving of the certificate shall not preclude the Board from claiming tax under subsection (4) above without limit of time.
