15A V.S.A. § 3-403: Manner and effect of service

(a) Service of the notice required by section 3-401 of this title shall be made in a manner appropriate under the Vermont Rules of Probate Procedure unless the court otherwise directs; provided however, a parent or alleged parent who has not consented to the adoption or whose parental rights have not been terminated shall be personally served in accordance with the Vermont Rules of Civil Procedure.

(b) Except as otherwise provided in subsection (c) of this section, a person who fails, without good cause, to respond to the notice within 20 days after its service may not appear in or receive further notice of the proceeding for adoption.

(c) If a person is a respondent in a petition to terminate the relationship of parent and child and the petition is served upon the respondent with the notice required by section 3-401, the respondent may not appear in or receive further notice of the proceeding for adoption or for termination unless the respondent responds to the notice as required by section 3-503 of this title.
