P.R. Laws Ap. tit. 32A, § III, Rule 56.4
If the requirements of Rule 56.3 have been met, the court shall issue, on motion ex parte of a claimant, an order of attachment or of prohibition to alienate. The attachment and prohibition to alienate real property shall be effected by recording them with the Registry of Property and notifying the defendant. In case of personal property, the order shall be carried out by depositing the personal property in question in court or with the person designated by it under the claimant’s responsibility. On petition of any of the parties the court may order the auction and sale of fungible goods whose attachment or prohibition to alienate has been issued and the proceeds thereof shall be deposited in the manner provided by the court.
The party requesting the designation of a depository of the property to be attached shall furnish his address and telephone number, if any, of his residence or of his place of employment or business. The designated depository shall immediately notify the court, under the title of the case, any change of address or telephone number, or of place or conditions of the property attached.
