A landowner entered into a redevelopment agreement with a builder, expecting Rs 4 Crore and two flats. However, the registered agreement only mentioned the flats, and the builder has been slow to pay the cash component and complete the project. An unregistered MOU later clarified the landowner's share, but its validity is questioned. The landowner seeks advice on whether the MOU is legally binding, how to prove their agreed share, and which court (civil, consumer, or RERA) is most appropriate for their case, especially given discrepancies in project completion dates and the builder selling flats before registration.
