Signature forgery

Hi sir, My sister was working in a company where she has forged signature of seniors on a normal A4 sheet paper for the sake of making the process of working easy. She has not signed on any letter heads of company, cheques, common seal etc. Now she has resigned due to her marriage and the company has lodged a FIR against her the company has also mentioned that her partner was also involved in this also she was a part of a racket, she has earned a lot of money from the customers by this signatures and company has suffered a loss. We are proceeding for her bail. But we got to know the company has not received any proofs against her, i just want to know what is the further process after the bail. Will her in laws have to also come to the court because they are unaware of all this, might be possible after knowing everything they can proceed for divorce. Please inform me the further processes after knowing that now the company is not interested in this case they are doing nothing for this case as they have not got any proofs against my sister.
