R.I. Gen. Laws § 33-5-9.1: Revocation of provision in will for divorced spouse.

The entry of a final judgment in the divorce of a person shall act as a revocation of all provisions for the benefit of the former spouse in a will made by the person prior to the divorce, unless it appears from the will that the will was made in contemplation of the divorce. All other provisions in the will shall take effect as though the former spouse had predeceased the person.
