I have been asked to undergo DNA test to prove parent-child between me and my included dependant which are my ex-husband my two kids. The problem is we are divorced and he has remarried and the kids custody has been given to me which I have all the documents, I don't know how to go about this DNA since we are no longer together, I don't know if I have to contact the embassy and explain this to them or not. Please advice if I will need a lawyer to contact them with my divorce paper, don't really know what to do.
