Yes, the right to statutory paternity/partner leave is available to the civil partner of the biological mother of a child. It is also available to the partner of the biological mother of a child, where "partner" means a person of either sex who lives with the mother or adopter in an enduring family relationship but is not an immediate relative (i.e. is not the child’s mother or adopter’s: parent, grandparent, sibling, uncle or aunt).
The term ‘mother’ is defined in relation to paternity/partner leave as the mother who gave birth to the child i.e. the biological mother. However, it is recognised that in some female same sex relationships the term ‘mother’ is used for both parents.
Paternity/Partner leave is also available to the spouse, civil partner or partner of either sex of a child’s adopter, or to one of a couple who jointly adopt a child or for University staff who enter into a legal surrogacy arrangement.
