Unless Dev volunteers, Geet has a hope in hell to achieve her goal.
Since the Delhi police refused to write an FIR against Dev without proof, Dev isn't legally bound to submit his DNA sample.
If he does, it would be on his own volition. And if he does that, hats off to him.
Again, if the DNA matches, there is no way Geet can prove that the marriage took place....no record of it as far as I can guess.
Again, it would have to be Dev who admits to his fraud.
