Annexation deed by Luís Álvares de Madureira, son of Diogo de Madureira, administrator of the entail. Luís mentioned the division of his parents' inheritance made by the "Juíz dos Órfãos". By this annexation deed, he entailed more properties, fulfilling the entail's clause that stated that every administrator ought to entail more assets.

Annexation deed by Maria de Madureira, daughter of Luís Álvares de Madureira and Joana de Madureira. She declared that she had shared the inheritance of her parents with her brother Diogo de Madureira, heir to the entail, who was already deceased. Maria decided to include part of her inheritance in the entail and asked for it to be entered in the book and inventory of the entail.

Declaration deed by Luís Álvares de Madureira and Joana de Madureira, by which they decided to incorporate in the previously instituted entail the inheritance they had received from Pedro de Madureira, father of Joana and father-in-law and uncle of Luís Álvares. They also included the houses they owned in Rua Nova, in Porto, as well as estates in the outskirts of Porto and Guimarães. They also decided that the administrators of the entail would be obliged to celebrate perpetual masses in the chapel located in the farmstead of Freixo, the head of the entail.

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.

Donation deed by Inês de Madureira, giving all her inheritance to her sister Isabel de Madureira.

Entail foundation deed by Luís Álvares de Madureira, fidalgo da casa do rei, his wife and first-cousin Joana de Madureira, and his aunt Isabel de Madureira. Together they decided to establish an entail, using their farmstead of Freixo, in Guilhabreu, as the head of the entail. They decided to create the entail in order to avoid the division of the estates and the dilution of the memory of the lineage, arguing that the concentration of the inheritance in one institution, managed by the first-born, was also a way of supporting the other relatives. At that time, the couple had no children and decided that in the absence of descendants, the surviving member of the couple had the power to appoint the successor. However, the administrator of the entail should primarly be the first-born son, excluding clerics and those who commited lese-majeste crimes. The administrators were also required to entail other lands and to use the Madureira name and coat of arms. An inventory of the entail was to be made, with three copies: one to be kept by the administrator, and the others to be kept in the Municipality of Porto and in the Cathedral.

Genealogical narrative, included in the book of the entail, presenting the history of the Madureira lineage until 1597. The narrative states the origin of the lineage, how they became citizens of the city of Porto, their marriages and generations.
