R.I. Gen. Laws § 33-15-32: Sale or mortgage of real estate.

If the personal property in the hands of a limited guardian or guardian is insufficient to pay the debts of his or her ward, including incumbrances on the ward’s estate, and the expense of supporting the ward and his or her family, and if the limited guardian or guardian has authority to make decisions regarding the ward’s real property, the limited guardian or guardian may be authorized by the probate court to sell, or to mortgage for an amount decreed, the real property of his or her ward or any interest therein for the purpose of paying debts. A limited guardian or guardian may also be authorized to sell the real estate of his or her ward or any interest in real estate for the purpose of making a better investment or for any other proper purpose.
