Declaration deed by Luís Álvares de Madureira and Joana de Madureira, adding some clauses to regulate the entail previously instituted. They established that the properties of the entail could not be given as dowry, nor used to ransom captives. The parents had the right to disinherit the presumptive heir of the entail if he married without their consent, unless the marriage was with a person of honorable lineage. Furthermore, the administrators of the entail were compelled to live in the city of Porto or in its 'termo', unless their service to the king obliged them to live elsewhere. They also required the heir to entail his reserved portion, his inheritance and that of his siters who became nuns, arguing that the monasteries where they lived should abdicate from the estates, since they belonged to the institutors' grandparents and ancestors, and should therefore be included in the entail.
