Hi, My marriage was solemnised with the UK citizen in india in the year 2007. I had got the marriage registered here. However after 2 years of separation, my ex husband had filed for a divorce in the UK on the grounds"the marriage had irretrievably broken down, the facts found proved being the respondent(myself) unreasonable behaviour". I was sent the notice of the proceedings through emails by the Nottingham county court. It stated in it that the court had jurisdiction to hear the case under" Article 3(1) of the Council Regulation(EC) No 2201/2003 of 27 November 2003". I haven't participated in any of the proceedings as I didn't had the visa to visit the UK. However, I had accepted these grounds of divorce and had signed , scanned the papers and emailed back to them I had not engaged any lawyer in india to contest my case as I had no issues to accept the divorce myself. I had finally received an original copy of final decree from the Nottingham court stamped but not signed with the divorce date august 2012. I haven't done anything to register this case or decree in indian court. Please advise.
