I was having a debate with my family as to whether or not two people adopted as children into the same family, making them lawfully siblings, could then go on to marry as adults, or whether it is against the law? Can't find the answers anywhere and are really interested!
Lol, ok, so which of you is 100% sure about the answer, cos I got different answers

and I'm not suggesting anyone would want to, merely questioning the law. Thanks for answers!

Thanks everyone for posts - we have now found in the Civil Partnership Act 2004 it IS illegal to marry an adoptive sibling. Hugely interesting subject I think..but then I suppose I would with my mum and dad foster carers for 10 yrs and being a Social Work student!!! Thanks again
