I’ve heard of those, but I don’t think Megs cares all that much for the legalities. She can get it done outside the UK and Harry’s pretty far down the line of succession.
That being said, I’m in the minority about the surrogacy. The Talking Tarot blog, for example, is pretty sure it’s not surrogacy.
I’ll say it again. Surrogacy contracts are NOT legally enforceable in the UK.
And the kid needs to be born in the UK as part of the royal family.
