Unreliable type made bankrupt by necessity? About right (6,4)
I believe the answer is:
broken reed
'unreliable type' is the definition.
(unreliable or ineffectual person)
'bankrupt by necessity? about right' is the wordplay.
'bankrupt' becomes 'broke'.
'by' means one lot of letters go next to another.
'necessity?' becomes 'need' (necessity is a kind of need).
'about' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'need' enclosing 'r' is 'nreed'.
'broke'+'nreed'='BROKEN REED'
'made' acts as a link.
(Other definitions for broken reed that I've seen before include "Weak person" , "You can no longer rely on this" .)
