will also gives to him or her absolutely the income to arise from the fund before he or she reaches that age, or directs the income, or so much of it as may be necessary, to be applied for his or her benefit, the bequest of the fund is not contingent. 108. Vesting of bequest to members of a class attaining particular age. Where a bequest is made only to such members of a class as shall have attained a particular age, a person who has not attained that age cannot have a vested interest in the legacy. PART XIV—ONEROUS BEQUESTS. 109. Onerous bequest. Where a bequest imposes an obligation on the legatee, he or she can take nothing by it unless he or she accepts it fully. 110. One of two separate and independent bequests to same person may be accepted. Where a will contains two separate and independent bequests to the same person, the legatee is at liberty to accept one of them, and refuse the other, although the former may be beneficial and the latter onerous. PART XV—CONTINGENT BEQUESTS. 111. Bequest contingent upon specified uncertain event. Where a legacy is given if a specified uncertain event shall happen, and no time is mentioned in the will for the occurrence of that event, the legacy cannot take effect unless the event happens before the period when the fund bequeathed is payable or distributable. 112. Bequest to persons surviving at some period not specified. Where a bequest is made to such of certain persons as shall be surviving at some period, but the exact period is not specified, the legacy shall go to such of them as shall be alive at the time of payment or distribution, unless a contrary intention appears by the will.
