Interesting case:
https://www.google.ie/amp/s/amp.theguardian.com/society/2017/oct/06/man-loses-damages-claim-against-ivf-clinic-over-forged-consent
Wealthy man's xgirlfriend, forged his signature, and uses a frozen embryo to get pregnant after they broke up. He sues the clinic for negligence but loses despite the judge remarking;
"Although [the father] has lost this case, my judgment must be seen as a complete personal and moral vindication. The same, of course, cannot be said for the mother" ...accusing her of " mendacious embellishment”...and making up evidence "as she went along.”
He seems well healed, so can probably afford to provide "private education, nannies, her wedding, university education, skiing trips, refurbishing her bedroom and a Land Rover Discovery used to transport the girl and his eight-year-old son."
What a bitch though, looks like she has totally gotten away with it.
