Valens, Trusts, Book VII. Javolenus gave it as his opinion, with reference to an heir who having been charged to pay a certain sum of money after the lapse of ten years paid it before the expiration of the time, that, if it could be proved that the trust had been left for the said period to benefit the party entitled to it, because he could not take care of the property, and the heir paid him the money before the time, knowing that he would squander it, he will, under no circumstances, be released from liability. If, however, the time had been fixed on account of the heir, in order that he might profit by the delay, it is understood that he will be released; and, indeed, it may be said that he paid more than he should have done.
