CIVIL CODE
SECTION 739-742
739. A future interest, depending on the contingency of the death of any person without successors, heirs, issue, or children, is defeated by the birth of a posthumous child of such person, capable of taking by succession. 740. A future interest may be defeated in any manner or by any act or means which the party creating such interest provided for or authorized in the creation thereof; nor is a future interest, thus liable to be defeated, to be on that ground adjudged void in its creation. 741. No future interest can be defeated or barred by any alienation or other act of the owner of the intermediate or precedent interest, nor by any destruction of such precedent interest by forfeiture, surrender, merger, or otherwise, except as provided by the next section, or where a forfeiture is imposed by statute as a penalty for the violation thereof. 742. No future interest, valid in its creation, is defeated by the determination of the precedent interest before the happening of the contingency on which the future interest is limited to take effect; but should such contingency afterwards happen, the future interest takes effect in the same manner and to the same extent as if the precedent interest had continued to the same period.
