Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
What links do you still have in the UK?
Then you have sufficient links to allow you to issue a petition based on the fact that you have lived apart for more than five years
You will also have to apply for permission to go ahead without serving the paperwork on him
But will have to show that you have actively attempted to trace him
I hope that this is of assistance - please ask if you need further dteails
