Tax affairs during probate

My 4 siblings & i have been left the family home value 450k euros but in the will one of our brothers is allowed to reside in the home until he passes which is fine by all of us...my question is during probate do the beneficiaries tax affairs have to be paid up in full even if the home is not getting sold anytime soon...and do we still have to go through probate given the home is not getting sold?

Yes, you have to go probate- the ownership of the property is changing

Any taxes due are payable as well, but if the 450k is divided between you all, no CAT is likely to be due
