Is it possible for a family court to distribute pension b/w two wives

We r from Hindu family. My father was govt employ, but 2 months back expired due to illness. My mother is first wife & they had 2 children myself & my sister (unmarried). My dad had another wife & a daughter (married). Now my dad's 2nd wife claiming for pension. But we r convincing her that it's not possible to grant pension for 2nd wife. Someone suggested her that it's possible in family court as both wives compromised outside court for equal proportion pension. So judge obey appeal & order to grant pension b/w 2 wives. My question is that is this possible in court & duration of trails.
