[001] she had claimed while alive, the exception of gift could be raised against her, against [002] which she could replicate that she could not gainsay her husband, [which] replication [003] does not lie in the mouth of the heir, because when he says my mother could not gainsay, [004] by that he shows that the replication lies for the mother and not for him, nor [005] could the heir properly say that his mother had to do the will of her lord, nor may the [006] heir be certain as to the intention of his mother, who perhaps, had she lived, would [007] never have revoked the gift.12<In truth though he has no inheritance3 from his [008] father, and thus is not his heir, as is evident, he cannot claim since he is bound to warrant, [009] though the mother could claim; he is bound to warrant as heir, because here he [010] will be the heir of his father because of the homage and service which ought to descend [011] to him from his father's seisin, though the feoffment was made of the mother's inheritance. [012] For one may give another's property to hold of himself and his heirs, and [013] by reason of such feoffment his son will be his heir, though no other inheritance descends [014] to him, but he is not bound to escambium except from that which descends to [015] him from his father's inheritance.4 It would be otherwise if the father gave it to be [016] held of others than his heirs, as of the chief lords or others.5 And what if he says of the [017] wife and her heirs? This does not bind the wife nor her heirs. But what if the wife [018] claims and the common heir is vouched to warranty? He is bound to warrant, for the [019] reason aforesaid; she will recover, and the common heir, since he has nothing from [020] the paternal inheritance, will not be bound to escambium, though he is bound to [021] warrant, and after her death he will succeed her in that land and is not bound to give [022] escambium from it.6 Hence it is evident, whatever others may say, that if the mother [023] dies before her husband, and her heir by the same husband claims, that since he is [024] bound to warrant, he ought to be barred from suing for what he could not recover, [025] though he is not bound to escambium from the mother's inheritance. In truth if [026] neither the father nor the mother has another heir, as where the father has no son by [027] another wife nor the wife by another husband, but the two have a single heir, such [028] heir cannot revoke his father's gift of his mother's inheritance since he is bound to [029] warrant as heir, for the reason aforesaid. But the mother may do so if she survives her [030] husband, and thus the thing so given may descend to the common heir, since by the [031] mother's act the father's gift is destroyed, which cannot be done by the common heir. [032] If they do not have a common heir, the mother's heir may well reclaim the gift, and [033] the father's heir by another will be bound to warrant and escambium,
