'doubles up' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?

'regarding participating in court events' is the wordplay.
'regarding' becomes 're' ('re' means regarding or about).
'participating in' indicates putting letters inside.
'court events' becomes 'cases' (I've seen this in another clue).
're' inserted inside 'cases' is 'CREASES'.

Can you help me to learn more?

(Other definitions for creases that I've seen before include "Pressed lines or crinkles" , "Cricket lines" .)
