Tenerife court dealt with forger (13)
I believe the answer is:
counterfeiter
'forger' is the definition.
('counterfeiter' can be a synonym of 'forger')
'tenerife court dealt' is the wordplay.
'dealt' indicates an anagram.
'tenerife'+'court'='tenerifecourt'
'tenerifecourt' is an anagram of 'COUNTERFEITER'.
'with' acts as a link.
(Other definitions for counterfeiter that I've seen before include "person making money illegally" , "Forger" .)
