"Where a child's father and mother were married to or civil partners of each other at the time of the birth, they shall each have parental responsibility for the child."
"In this Act and enactments passed and instruments made after the coming into force of this section, references (however expressed) to any relationship between two persons shall, unless the contrary intention appears, be construed without regard to whether or not the father and mother of either of them, or the father and mother of any person through whom the relationship is deduced, have or had been married to each other at any time."
" In this Schedule, except paragraphs 2 and 15, “parent” includes— (a) any party to a marriage (whether or not subsisting) in relation to whom the child concerned is a child of the family, and (b) any civil partner in a civil partnership (whether or not subsisting) in relation to whom the child concerned is a child of the family; and for this purpose any reference to either parent or both parents shall be read as a reference to any parent of his and to all of his parents."
"It has been held that if a legal presumption is allowed to prevail over biological and social reality, this may amount to a breach of Article 8. (See Znamenskaya v Russia (Application No 77785/01) [2005] 2 FCR 406)."
"In the Court’s opinion, "respect" for "family life" requires that biological and social reality prevail over a legal presumption which, as in the present case, flies in the face of both established fact and the wishes of those concerned without actually benefiting anyone."
