How can I take action against a false affidavit?

My sister in law has given a false affidavit with her bail application( rejected ) in the sessions court where her signatures are forged and she has shown her as a married woman whereas she is unmarried. The same woman now in her bail application affidavit in High court has shown herself as unmarried and her signature also entirely different from the previous affidavit . now my querry is that if I file an application under sec 340 in High court where her bail application is yet to be heard what will be the action by High court secondly if HC accepts my sec 340 application and she withdraws her bail application will High court still proceed with my application of section 340 or it will also get withdrawn . Please give your valuable views.thank you
