304b ipc not to get bail

My sister who was a state government employee was married to a private employee six months ago. Soon after marriage he began to torture her mentally and physically and asks for extra dowry. Recently she committed suicide and we filed a case against him on section 304b. After my sister's death he absconded and now applied for anticipatory bail (AB) in high court. Will high court sanction bail to him? Also how to obtain legal heir certificate of my mother to receive amulments from her job??
