Father's facing high jump perhaps for papers (8)
I believe the answer is:
passport
'papers' is the definition.
(passport is a kind of papers)
'father's facing high jump perhaps' is the wordplay.
'father's' becomes 'pa's' (pa can mean dad or father).
'facing' means one lot of letters go next to another.
'high jump perhaps' becomes 'sport' (high jump is a kind of sport).
'pas'+'sport'='PASSPORT'
'for' acts as a link.
(Other definitions for passport that I've seen before include "the key to success?" , "is the open sesame" , "Travel doc" , "Document allowing travel abroad" , "Authorization to go abroad and return" .)
