1. can i lodge a cheque bounce case . if so how much time it takes
2. since he is in dubai & may not return shortly , does cheque bounce case will have any effect on him
which cheque you are talking about. you have not stated about any cheque in your query. you have not even stated if any cheque exissted. you have not stated whether any such cheque is bounced. you have not stated when it was bounced. you have not stated whether the cheque is now valid.
you may not expect a workable advise without facts. This is not astrological forum.
3. can i register a police complaint under cheating & if i can get a FIR, if i send it to dubai police will t have any effect?
how do you p[rove cheating. your query does not indicate any wrong information givne by him.
given facts only indicate you to be a philonthropist who has just paid a fee of Rs 1 lakh to under stand that the money givne to friends relatives, cousines of self and spounce is a charity in the garb of loan never intended to be refunded.
