C.R.S. § 15-12-612

Except as otherwise ordered in formal proceedings, the probate of a will subsequent to the appointment of a personal representative in intestacy or under a will which is superseded by formal probate of another will, or the vacation of an informal probate of a will subsequent to the appointment of the personal representative thereunder, does not terminate the appointment of the personal representative although his powers may be reduced as provided in section 15-12-401 . Termination occurs upon appointment in informal or formal appointment proceedings of a person entitled to appointment under the later assumption concerning testacy. If no request for new appointment is made within thirty days after expiration of time for appeal from the order in formal testacy proceedings, or from the informal probate, changing the assumption concerning testacy, the previously appointed personal representative upon request may be appointed personal representative under the subsequently probated will, or as in intestacy as the case may be.
