Fake 498a case against me and my family member

The Hon'ble Supreme Court of India and various Hon'ble High Courts have taken a stern view on blatantly filing an FIR in the case of 498A. The police officer would unlikely to file an FIR against you or your family members unless influenced by extraneous circumstances. The police officer/IO would also hear your version before lodging an FIR.

You can file an Anticipatory Bail Application if you have strong apprehension that FIR is likely to get registered, however, the chances of the Application being allowed at this stage is a bit tricky which depends upon the facts and circumstances of the case.  

The last hearing at the Women’s Cell (Uttar pradesh) is next week, and now I’m confused. If an FIR is filed on the day of the last hearing, can they arrest me on the same day?

Since they have fixed the date for inquiry on the next date, you may appear before them and participate in the inquiry section, cooperate with them.

If you apprehend arrest then you may be accompanied by a lawyer who will bring you out of the police station safely in such an event after which you can file an application for anticipatory bail.

Can I file anticipatory bail before going there

Get an aticipatory bail and only then appear in PS .

Its women cell where they decided that FIR will be filed on next date

Police have no powers to arrest just because an FIR alleging offence undr 498A filed. Why you should rush to get anticipatory bail if the allegations are false?
