Adoption Deed for Passport

I was a divorcee and got remarried in 2012. I am twins from my first marraige and now we are suffering in making the passports for my kids bcoz legal adoption is not there. In school and on all documents kids are having the new father's surname. But while we applied for passport two years back we learnt that we need a legal addoption deed as a document for passport...And immediately we filed a court case in October-2015 for this. In my Divorce paper custody of kids is with not mentioned. My ex-husband refused to give NOC though he has never seen the face of teh kids since they were 4 months old. Till date we have not received any result from the court that since there are only dates going on in the court. The advocate says nothing is happening...the judge is not willing to listen anything and gives the next date. We both are in dubai and kids are back in India with my parents who are really aged to take care of the kids. We can't go back to India since has many financial responsibilities and kids are unable to come here because of the passport issue. We are going thru the mental trauma everyday single. Please let me know any way out of this.
