1. Can he file divorce in Hyderabad, when Marriage took place in Jaipur and both are permanent residents of UK.
2. If he can then can he send divorce notice to her at my address at Jaipur.
3. If we refuse to accept the notice as our daughter is not there, will it lead to her not appearing for court hearing and can family court of Hyderabad issue ex-parte decree?
For all the above questions, since the marriage has not taken place at Hyderabad, nor they both lived or last resided together in Hyderabad nor she is living at Hyderabad now, the divorce case intended to be filed a t Hyderabad by him will be barred by jurisdiction. If somehow he manages to file a case at Hyderabad by bribing the corrupt court officials and sends a summons to your Jaipur address or to her present address, accept the summons from court, get a power of attorney deed executed by yor daughter in your favor or somebody who will be able to travel to Hyderabad to attend the court for this case and i the first appearance itself an application to reject the case can be filed mentioning jurisdictional issue. The court if satisfied with the documentary evidences provided for your claim , may reject the divorce case.
since your daughter has already initiated a DV case against him elsewhere, the details of the same also can be provided to prove the jurisdictional issue. Suppose the court is rejecting the application for rejecting the case, you may prefer a revision against it before the high court and fight to get the cae rejected.
In fact she can file a domestic violence case and divorce or maintenance suit in UK itself based on the joint ownership of the property held in UK as well as her citizenship status. This will bring to the edge of the seat and may come to a negotiable terms when being attacked from all corners.
