Hello
My son and his Chinese wife have separated. The three children were all born in China, but now have UK passports and lived in the UK for 3 years. One of the reasons for the separation was that my Daughter-in-law wanted to return to China. During arguments, she always threatened to take the children (either all of them of just one/two). The parents have an informal agreement to share custody. I am now frightened that my DIL will take the three children and disappear into China. Does my son have any legal rights to keep the children in the UK?
