How to get ex parte order?

Sir, I am Mrs. Chakraborty. My husband has deserted me around 6 yrs back after a conjugal life of 1.5 yrs. I stay in my father's place with my only son. We used to stay in a rented place. The Last half of our married life was bitter & he used to do lots of physical assault. I left his rented house after such an incidence with my father & filed a GD in the court. I have been looking for divorce & the case sub judice but he has never appeared the court & all summons are refused from his uncle's house which I was told is his permanent residence.His current location & status is unknown to me. I don't have any clue. Court is asking for proof of his address for granting paper publication order. I don't have any doc proof of his address. I applied to the PIO of the Bank where he had his bank A/C but PIO also refused to furnish the document.I changed couple of advocates but no one is showing the right way. I have financial limitation also. Kindly let me know the way out. How to get paper publication & ex parte order. Regards Ms. Chakraborty
