This is a situation for you MarkR because why would your girlfriend be involved with a married man?
It would be easy for her to let the legal wife know about the situation and that will ease some issues between you and your gf. Get them (the father of the children and his wife) over to be involved since it is big decision. That is if you are going to support your gf and her children.
Late registrations will not work anymore. The NSO are now keen about birth simulations and late registrations. It can also lead to more issues in the future when you want the children to come over.
Why not talk over with the father of the children? He is not in the position to command your gf like that as if he owns her like a property.
OMG what happen to the women's right
