A family business operating for 50 years in a prime location shop under a pagdi system is facing a situation where a distant relative of the original deceased landlord has been falsely claiming to be the new owner for 30 years. The business has been paying rent and property taxes to this individual, only to discover the property was never legally transferred. The query seeks advice on suing for falsely collected rent, claiming a refund with interest, and whether to continue paying rent.
