Help in false case of dowry seeking

Yes, you will need to go to Chennai. You may not have attended the marriage or kept contact with her, she may have added your name to harrass your brother, but now that your SIL have implicated you in the case, you should do the needful to get the FIR quashed against you.

first of all it is "quash" and not "sqaush"

My brother told me that he has got anticipation bail for me and him. But I need to go to Chennai to sign the bail. Is it true?

strange do not trust your brother.  how can you just imagine to be c*ntinuing on bail without being at chennai on all dates.

How can I am party, when I did not attend marriage, sought dowry? will Squash happen? How to get rid of this woman?

For dowry demand one does not need to be present under one roof with the bride.  The demand/torture can even be remote. So being away from chennai is no proof of innosence.

How many days I have to go to Chennai?

each and every hearing.  Even if it is twice  a month or twice a week.  Unless court grants exemption from personal hearing.

Whether Quashing would happen or not would be decided on reading the FIR. There are very limited legal grounds on which the quashing does happen.

Did you send any signed documents for applying for AB, if you did not, then be wary, your brother has not got any AB for you.

Regards,

seen facts as stated by you. frist go to chenni,and comply order of court about bail. if you have sufficient proof that you have not demanded dowry, submit before court  toquash f.i.r. u/s482cr.p.c. before high court. you may get favourable order.prakash jain adv.
