How nominee should claim mutual funds money?

My uncle bought mutual funds. In some of them , he nominated my aunt. For rest, we could not see any nomination. They are different fund companies, like SBI, Sundaram finance and so on. He died in 2010. What should my aunt do to claim the money by returning the units? Whom should she visit? Will there be a one stop place where she can get it done or she should go to each office?
Thanks for your help.
