Refund procedure

My case was settled in Mediation. It was settled almost a year ago. I have the following query: 1. Is there any limitation period for taking refund of court fee? 2. What are the documents that are required to be submitted ? 3.Time period after submission of documents, it will take to receive the refund amount? 4. How will I be granted the refund of court fees (Cheque / Cash)? 5. In case the person is not available to collect the refund fees . Can some other person collect the same and documents that would be required for it ? Thanks in advance
