Conn. Gen. Stat. § 45a-187: (Formerly Sec. 45-289). Time of taking appeals.

(a) An appeal by persons of the age of majority who are present or who have legal notice to be present, or who have been given notice of their right to request a hearing or have filed a written waiver of their right to a hearing, shall be taken within the time provided in section 45a-186, except as otherwise provided in this section. If such persons have no notice to be present and are not present, or have not been given notice of their right to request a hearing, such appeal shall be taken within twelve months, except for appeals by such persons from an order of termination of parental rights, other than an order of termination of parental rights based on consent, or a decree of adoption, in which case appeal shall be taken within ninety days. An appeal from an order of termination of parental rights based on consent, which order is issued on or after October 1, 2004, shall be taken within twenty days. The appeal periods set forth in this section shall be calculated from the date on which the court sent the order, denial or decree by mail or the date on which the court transmitted the order, denial or decree by electronic service, whichever is later.

(b) An order, denial or decree of a Probate Court shall not be invalid because of the disqualification of the judge unless an appeal therefrom is taken within the time provided in this section and sections 45a-186 and 45a-188.
