“Where a child was conceived by a mother and a father by virtue of an agreement between them that the child would live with and be brought up in the care of the mother and her female partner as the primary care givers of the child, there could be no general rule in family proceedings that the biological father was to be regarded only as a ‘secondary’ parent or to have a limited relationship with the child. Each case was fact specific and the welfare of the child was paramount.”
