Legal agreements for shrinks (9)

I believe the answer is:

contracts

I believe this is a double definition.

'legal agreements' is the first definition.
(I've seen this before)

'shrinks' is the second definition.
(contracting is a kind of shrinking)

'for' is the link.

(Another definition for contracts that I've seen is " Legal agreements".)

I've seen this clue in The Guardian.
