Entail foundation deed by Pedro Gonçalves do Lago. The founder declared his will to perpetually entail and unite his properties in São Martinho de Escariz, the income from which would also support masses for the benefit of Pedro's soul, as well as that of his parents and relatives. The masses were to be celebrated in the Convent of Salvador in Braga. The first administrator of the entail was to be his brother, Manuel Ribeiro do Lago, followed by his descendants, with preference given to first-born sons. The administrators had to be mentally and physically fit. Clerics, illegitimate children and those who had committed lese-majeste crimes were excluded. In addition, the institutor required the administrators to register the institution in the "livro da provedoria desta comarca", in Braga, and also in the records of the church where the masses would be celebrated.
