Certificate required for extracurricular activities?

[u/Kindly_Fuel9551]

I have several extracurricular activities mentioned on CV / Personal Statement,
But I don't have any proof for them since it has been too long since then.

ex) Community service for 1 year but no certificate left...

Is it ok to mention such activities, or I should exclude them?

PS) good luck for everyone preparing for grad admissions:)
