Where a minor is appointed executor jointly with one or more other executors, probate may be granted to the executor or executors not under disability with power reserved to the minor executor, and the minor executor shall be entitled to apply for probate on attaining the age of eighteen years.

Administration for the use and benefit of a minor executor until he attains the age of eighteen years may be granted under rule 32 if, and only if, the executors who are not under disability renounce or, on being cited to accept or refuse a grant, fail to make an effective application therefor.
