Reporter runs into person cited in divorce proceedings (13)
I believe the answer is:
correspondent
'reporter' is the definition.
(I've seen this before)
'runs into person cited in divorce proceedings' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'into' means one lot of letters goes inside another.
'person cited in divorce proceedings' becomes 'corespondent'.
'r' going within 'corespondent' is 'CORRESPONDENT'.
(Other definitions for correspondent that I've seen before include "Reporter on special subject or from overseas" , "Pen-friend" , "Newspaper writer" , "Journalist; pen pal" , "Reporter on specialist areas" .)
