depreciated value given back after repair done?

so i recently had an accident in my business and the insurance paid for some equipment that were damaged. They also held back depreciated value and told me when all repairs are done to send them everything and the depreciated amount will be given to me. Now my question is if we decided not to use all the money given for repairs...to repair the equipment ..and i give them just the amount we used will they hold back that depreciation value or still give it all back?

thanks
