Will by which Diogo Álvares Barrenho established an entail with all his assets, instituting the obligation that its administrators celebrated, every year, ten masses. He designated his sister, Inês Pires, to administrate the entail and his niece, Beatriz Garcia, to succeed her. Beatriz should only receive the administration if she married, and until then, the administration should be delivered to a tutor. After her death, the succession should always continue, preferably, on the closest and eldest male relative.
The testator determined that his body had to be buried near the altar of S. João, in the church of Espírito Santo of Alter do Chão.
