Bail application

Is it necessary for a surety to furnish a Solvency Certificate. For example, Mr. X wants to stand surety for Mr. Y whose bail application is allowed on the condition that Mr. Y would furnish a PR for Rs.50,000 and a surety of the like amount. Now is it necessary for Mr. X to furnish a Solvency Certificate or only FDR of Rs.50,000/- would suffice.
