hello to all

i have got a leasehold property in dr mukherjee nagar with registered power of attorney on it. i have got all the docs but i recently i checked that the lease deed is not there in the docs and when i asked someone about this, then he said to some properties dont have a lease deed. so what can i do now? apart from it i have got all the docs…like allotment letter, posession slip an all…
