Canon 1043

1. Those who in virtue of natural or canon law can freely dispose of their goods can leave them to pious causes either by an

act which becomes effective during life or at death. 2. The

prescriptions of civil law are as far as possible to be observed

in the last wishes made for the good of the Church; if these prescriptions are not observed, the heirs must be advised of their

obligation to fulfill the will of the testator.
