R.I. Gen. Laws § 34-27-3: Discharge of purchaser at sale by payments to mortgagee.

The receipt in writing of a mortgagee shall be a sufficient discharge for any money accruing from sales made under the powers of sale conferred by his or her mortgage; and a person paying it to the mortgagee shall not be obliged to inquire whether any money remains due under the mortgage, or to see as to the application of such proceeds in case of sale.
