I entered in a Sale agreement in June2010 of my Property and Buyer issued 4 cheques 1 current dated and 3 within 45 days after registration all the cheque details mentioned in the sale deed, 2 cheques materialised but the 3rd and 4th Cheque he requested us to present it after 2 weeks from the cheques date, since then he kept on posponing and it is 5 months now he is still asking us not to present it,
Please Advise what should I do, is it possible to make the registration Viod by approaching the Registrar?
