Is it correct to claim pension when the husband is in a nursing home for dementia?

A friend of mine her father-in-law is in a nursing home for dementia for over 6 months. Her mother-in-law is still claiming all the pension for both i did'nt think you could claim it after 6 weeks if this is correct will the money have to be repaid they don't pay any money to the nursing home .
