Dear Lawhands, first of all accept my apology for being straight in this context.Secondly you would have to face many hurdles in such a situation:
a) Hiring a sincere lawyer itself is a herculean task.Because had it been not so, you would not have approached the LCI.But please keep on imploring your lawyer.
b) Once you sign on the VAKALATNAMA ( A power of attorney in the name of a lawyer) though theoretically client is considered master and a lawyer has to act as per your advise of client but it becomes reverse and you have to be on his mercy because a lawyer doesn't follow any code of conduct and he is law unto himself.
c) If you have all the details of that erring husband's passport, his tentaive departure date, his flight number etc then you can approach IMMIGARATION at the respective airport, if not possible, then kindly raise an RTI but you have to furnish all the particulars about him and not the vague request.
d) You can submit that information to the Indian court of the case and request suitable action.
e) It would be a herculean task to serve any Summons on him abroad even with the help of External affairs at India and the Indian embassy abroad because you are unaware of his residence over there.
f) Keep on following the case and pressurize, implore, request, beg his parents, relatives in India to help them, you may succeed or not.
g) Try to find out any lacunae/false information in his passport application form with the passport issuer at India and initiate imponding actions if found to be incorrect.
h) Keep on trying with his employers at India if any for information on him.
i) Have faith on god,though you may find it illogical but I do have it on him.
Thanx and regards,
