When a mortgagor of personal property is summoned as trustee of the mortgagee, the plaintiff may direct the officer serving the writ to attach the mortgagee's interest in such property. The officer when so directed shall attach such interest by leaving a copy of the writ in the town clerk's office where the mortgage is recorded, with his or her return thereon describing the property and the interest of the mortgagee therein. The town clerk shall enter upon the margin of the record of such mortgage, a statement that the interest of the mortgagee is attached, and make such other record and entry as is required by law to be made where property is attached by copy.
