since amount involve is rs 10lakh then can go to district court of vaishali and my permanent residence is hajipur vaishali .
You can approach the jurisdictional court only, your lawyer would be able to file the case in the appropriate court, so dont worry about this.
A local lower advice me that I hve to approch high court to stop payment to nominee by LIC
It is sheer misguidance. You can consult a different and knowledgeable lawyer.
Lic inform me in written that if I won't take stay order from court then they will proceed the claim in fvg og nominee.
They are right in saying so because they are bound to answer the claimant i.e., your father in law otherwise he may drag lic to consumer forum for unnecessary delay in settlement of claim amount.
Kindly advice me that what will be best district court hajipur or high court patna . I don't want to approch Aurangabad court for some reason
The court within whose jurisdiction the lic branch office falls shall be the proper jurisdiction.
You can consult a good lawyer with proper knowledge on the subject.
