client passed away. account was transferred in an estate account. account holds mutual fund positions. half of account goes to brother and other half to charities.

questions:
a. does brother get a step up in basis on his half?

b. can he take ownership of his half of mutual funds or does the estate liquidate everything and then send a check to him?

c. Can he take ownership of every mutual fund position and then pay the estate back half of the money in cash for the chariy share?

Thankyou,
Douglas
