Entail foundation deed by Rui Brandão, fidalgo da casa do rei. The founder reserves his "terça" and includes in it several urban and rural estates, the head of which is the "Torre de Pedro do Sem", located in the parish of S. Martinho de Cedofeira, outside the walls of Porto, to which the patronage of the church of S. Paio de Guimarei was attached. Rui Brandão appointed his son Luís Brandão, or alternatively Diogo Brandão, as the first administrator. The heirs of the entail would be the first-born sons, or daughters in the absence of male heirs. The heir had to be physically and mentally fit, excluding people of illegitimate descent, clerics, monks, friars and nuns. The administratores had to live in Porto, marry with their parents' consent, entail half of their "terças", use the Brandão's name and coat of arms, and pay an annual rent to Rui's daughters, who were nuns in the convents of S. Bento de Avé-Maria and S. Clara in Porto. Perpetual masses were to be celebrated in the convent of S. Francisco do Porto for the soul of the founder and his wife, Maria de Madureira. Three inventories were to be drawn up, containing the deed of foundation and the property, with the coat of arms of the instituter: one copy was to remain in the hands of the administrators, while the other two were to be kept in the Convent of S. Francisco, where the founder was to be buried, and in the Misericórdia of Porto.
