Paid up and is taking possession of the articles (5)
I believe the answer is:
items
'articles' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for items that I've seen before include "Entries made by accountant" , "Individual articles" , "separate parts of news bulletin" , "Bits of news" , "Times (anag.)" .)
