Client's brother Jim died 2/14/2023 at age 82.  No distribution from his ROTH account made prior to death.

Beneficiary is brother Richard age 79.

What is distribution rule for Richard based on above?

Can money stay in Richard's inherited ROTH account for 10 years or until 2/14/2033? or is there a yearly RMD requirement for Richard?  if yearly RMD is required, what year would it start.

Thanks
