Sharing this as it's a really complex and fairly recent case that went through the U.K. courts. I'll try to summarise but suggest anyone with a strong interest read in full.
A husband and wife have a surrogate born son in another country. All of fine and the parental order goes through. Meanwhile the wife has instructed the overseas clinic to store her husbands sperm for longer and later uses it to have surrogate born twins with a different surrogate mother, also overseas, without his knowledge or consent. She takes £60k from the joint account and doesn't say a word at any social worker appointment or during legal proceedings for the parental order and doesn't tell her husband, the father until it it too late.
Understandably it all goes a bit wrong in their marriage and various accusations or assault are made and it all breaks down. The wife plans to travel to care for the surrogate born twins for two weeks then return to care for her the young boy for two weeks but she can't manage this.
Ultimately the son lives with the father but they both have parental rights and there is some discussion of how the boy will meet his twin half-siblings (different egg donor).
The mother is not related to any of the children but the father is the biological father and takes financial responsibility and says the twins are 'innocent'.

Though it is both international and commercial surrogacy so not directly connected, it is the U.K. courts that have the jurisdiction over the decision and it explains why when genetic material leaves your body it is important to retain consent.
As the law commission are using their position to justify what they call altruistic surrogacy to be kept in the U.K., the natural increase in cases will burden both the legal system and the NHS.
There was no real coverage of donor gametes in the LC's documents on donated gametes, as pointed out by that blog, so surely it's this sort of case that creates an argument for tighter restrictions around both this and surrogacy?
