You first confirm whether there was any notice issued to you, if so, procure the copy of the notice, then see if the compensation was paid, if paid whether tat was credited to your account and the compensation mount was paid in accordance with the prevailing law.
If compensation amount was not paid then whether you had taken up this matter with the concerned authority, secure the evidences of all these.
