Dowry deed by which Luís de Lencastre, 1º comendador-mor, founded an entail to his eldest son Luís de Lencastre, in order to marry with D. Filipa de Meneses, daughter of Diogo da Silveira, Conde de Sortelha and guarda-mor do rei. The institutor obligated himself to buy 400 000 réis of a public debt instrument or immovable goods, and separate one conto de réis from its rents for the entail. His son D. Luís de Lencastre obligated himself to incorporate a public debt instrument of 600 000 réis into this entail after his father's death, and to use his "legítimas" and the couple's third. The institutor also incorporated into this entail his rents from the "comendas" of Estremoz, Fronteira and Landroal. The successor's heirs should give the "arras" to D. Filipa de Meneses. Preceded by an alvará dated 1573-06-10.
