For those who are considering terminating a problematic relationship, the presence of children born of the relationship can represent a complicating factor if the intention is to return to their country of origin.
Most countries have laws that protect the rights of the other parent to have reasonable access to and time with their children. This would obviously become extremely difficult if the children were taken to live in another country.
The application of such laws is a complex matter requiring an experienced family lawyer to assist anyone who finds themselves in this situation.
