Hey I would love to know what happens to the flat for which I had already paid my instalments , the problem is there are few instalments for which i don’t have the receipt hard copy ack but i have the soft copy of it and since i took loan to pay instalments I wondering will that work in order to take possession of my flat , the absence of hard copy can cause issue or not , or how to tackle this. Please help me here if someone has knowledge about this issue
