P.R. Laws tit. 31, § 767
The following persons shall be exempted from giving bond for the tutorship:
(1) The father, the mother and the grandparents, whenever called to the tutorship of their descendants.
(2) The testamentary tutor relieved by the father or mother, in the proper cases, from this obligation. This exception shall cease when causes arise subsequent to the appointment of the tutor and which were not known to the testator, which make such bond indispensable in the judgment of the Court of First Instance.
(3) The tutor appointed and excused from giving bonds by strangers who may have made the minor or incapacitated person their heir or left him a legacy of importance. In this case, such exemption shall be limited to the property or income in which the inheritance or legacy consists.
