R.I. Gen. Laws § 10-5-45: Dissolution of attachment for failure to file complaint.

An attachment of property on any writ hereafter issued shall be dissolved if the complaint in the action is not filed with the court either before or within thirty (30) days after the attachment is made. A certificate signed by the clerk of the court to which the writ is returnable which states that according to the records of the court the complaint has not been filed shall be sufficient authority to dissolve the attachment and to release any funds or properties attached pursuant to the writ and shall further serve to release the garnishee from any liability that might exist by virtue of the issuance of the writ.
