So I've got a question relative to paternity in UK (as said in the title). So in my story, the dad left the mom before the child's birth, but they were still married (the divorce was done after the birth). So I assume the dad is technically legally the father, because according to wikipedia and a bunch of others websites : "A child born to the wife during a marriage under common law is determined to be the husband's child by a 'presumption of paternity'"even though he did not meet his kid until she grow up.
However, as the dad left, I wonder if he is stills legally the father or if the kid is consider fatherless, even though there is no possible doubt about paternity. I digged a little on google, and quickly found this : http://ciec1.org/Etudes/ColloqueCIEC/CI
So far I search using the word "paternity in UK" "fatherless child" "unwanted fatherhood" (An article I read on paternity implied that it could be realte to my situation, but it was not). I also tried some similar key word in French, without satisfying result.
My questions are :
1)Is the dad still the dad?
2) If not, can he recognize the kid or not (she's 18, so not exactly a kid but willingly to get along with her father and to have legally bond) ? Maybe in front of a court of something?
Because of my plots, the dad and the kid had to be legally bonded (she is sick and need a kidney that he is willigly to give her and because of law around it, it would be easier if he was legally his father).
Thank you for your future help =)
