R.I. Gen. Laws § 33-22-14: Findings of court as to notice.

If it shall appear to the court, before proceeding, that notice has been given to all known parties interested, in accordance with the foregoing provisions, and in a manner satisfactory to the court, it shall be sufficient to warrant proceeding; and its findings as to notice, unless appealed from, shall be conclusive. Notice by telephone, facsimile, e-mail, or other electronic transmission may supplement, but shall not discharge any party’s obligation under this chapter to give notice by service or mail.
