Look after the place when she is out misbehaving! (5,3)
I believe the answer is:
house sit
'look after the place' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'she is out misbehaving' is the wordplay.
'misbehaving' is an anagram indicator.
'she'+'is'+'out'='sheisout'
'sheisout' anagrammed gives 'HOUSE-SIT'.
'when' acts as a link.
Can you help me to learn more?
(Other definitions for house sit that I've seen before include "take care of residence" , "way to provide residential care?" , "take care of property" , "Look after building" .)
