Appellate Division of the Supreme Court of the State of New York July 18, 2012 (Alexandra D. v. Santos)

Pursuant to Domestic Relations Law § 71, a sibling may commence a proceeding to seek visitation with a whole or half sibling who is under the care, custody, and control of a parent or other person or party. Where the sibling seeking such relief is a minor, “a proper person” may seek such relief on his or her behalf (Domestic Relations Law § 71).
