Check list? (6)
I believe the answer is:
payees
'check list?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for payees that I've seen before include "Cheques are made out to them" , "The people who receive the money" , "To whom money is paid" , "Those who get the money as for goods or services" .)
