Joan Garcia was a royal notary who chose as his exectuors his daughter-in-law Sor Margarida Fontcabla, a nun at the Monastery of Montsion, and his own daughter, Elizabet, who, at the time of the will was not married. He wished to be buried with his wife Isabel in S. Pere de les Puelles in the place allotted by the abbess and instructs his heirs to make a stone to mark the burial place.

He specifies a number of Masses, one at the main altar of the Abbey of Montserrat, and a trentenari at the Franciscan monastery, where he also asks for the prayers of the lashes ('les orations dels assots o flagells de nostre señor'), and he also asks for a Mass to be sung there on the day of his burial by the friars ('sien tenguts a dir me o celebrar vna missa cantada lo dia de la mia mort o sepultura'. In the Monastery of Jerusalem he gives 40s for lighting and ceremony and a further 3l 'pregant les monjes de dit monastir vullen dir y fer vn offici cantat per la anima mia y de la dita muller mia'.
Among his personal bequests he leaves 6 ducats for his daughter Maria Anna Dorotea who is a nun in the convent to purchase a habit.
