P.R. Laws tit. 31, § 1544
Should the usufructuary not give security in the cases when he is bound to give it, the owner may require that the immovables be placed under administration, that the movables be sold, that the public securities, deeds of credit, either payable to order or to bearer, be converted into certificates or deposited in a bank or other public institution; and that the capital or sums in cash and the price of the alienation of the personal property, be invested in safe securities.
Interest on the price of the movables, and that on public securities and bonds, notes, stocks, shares, and others of a like nature (valores) and the proceeds or property placed under administration, belong to the usufructuary.
The owner may, furthermore, if he prefers, until the usufructuary gives security or is excused from so doing, retain in his possession the property in usufruct, as administrator, and with the obligations to deliver the net proceeds thereof to the usufructuary, less the sums which may be agreed upon or may be judicially fixed for the said administration.
