Maybe snipe and fight over case for divorce (5)
I believe the answer is:
wader
'maybe snipe' is the definition.
(I know that snipe is a type of limicoline bird)
'fight over case for divorce' is the wordplay.
'fight' becomes 'war' (warring is a kind of fighting).
'over' means one lot of letters goes inside another.
'case for' says to hollow out the word (remove centre letters) (the letters which encase the others are used).
'divorce' with its centre removed is 'de'.
'war' going around 'de' is 'WADER'.
'and' acts as a link.
(Other definitions for wader that I've seen before include "Long waterproof boot" , "Long-legged shore bird" , "crane, perhaps" , "Type of long-legged bird" , "Eg, sandpiper, flamingo" .)
