[001] made a gift subject to an agreement is unable to put himself in seisin; recourse must [002] be had to a superior. He will be given an action based upon the agreement when he is [003] out of seisin; when he is in seisin, he will be given an exception based on the agreement.1
Matters which bar restitution by the assise.
[005] Uncertainty, whether as to the thing itself, the body or2 tenement, or as to a right [006] appurtenant to the tenement, or as to the person of the plaintiff [impedes restitution].3 [007] I do not say this if certainty may by some means be secured or at least a presumption [008] raised, but if certainty can in no way be reached nor any presumption [009] raised.4 Negligence or dissimulation for a time, which are taken for consent, are also [010] impediments to restitution, not to the extent of destroying the action completely, [011] but to that of taking from the disseisee the right to re-eject immediately, for dissimulation [012] and gross negligence, which is taken for consent, gives the disseisor a quasi free [013] tenement, so that he cannot be ejected without judgment, and takes his privilege [014] from the disseisee, for since he is negligent it is at least presumed that he was not [015] unwilling to be disseised,5 and also that he has lost both possessions, natural and [016] civil. Similarly consent, whether it exists from the beginning or is given subsequently, [017] remits the injuria and quitclaims the tenement. A transactio [the compromise of a [018] doubtful claim] also impedes restitution, as where, for the avoidance of strife, he [019] remits part of the tenement and accepts part, which may be allowed him as a matter [020] of grace and for the furtherance of peace, not de jure, for with respect to things done [021] against the peace of the lord king there is no concord or compromise, only judgment, [022] according as the plaintiff withdraws or the disseisor acknowledges the disseisin. Confirmation [023] or consent also impedes restitution: [confirmation], as where the disseisee [024] confirms the things seized to the disseisor, for a confirmation willingly made nullifies [025] an injuria; consent, as where the disseisor makes a gift and the disseisee consents to [026] it and ratifies it, when it is first made or after a time.6 The disseisee's usurpation, without [027] judgment, of his own property after the disseisin also impedes restitution, but [028] only after time has passed, as where a disseisee is negligent in impetrating or prosecuting [029] or both; he cannot usurp his own property without judgment, as above.7 He [030] may accept it, however, if it is freely offered him. [Only sometimes, not always,8 for [031] example, A. disseises B., C. disseises A., or A. gives the tenement to C.; B. impetrates [032] against A. A. fearing the disseisin and the assise ejects C. without judgment and [033] restores the tenement to B., after impetration by C. or before. If C. sues A. alone and [034] not B., A. cannot restore. If he sues B. alone, B. did not disseise C. He thus must sue
