For one resale property I had done MOU with the owner. MOU is on 100 rs stamp paper and notarized. At the time of MOU I had given 1L rs cheque to the owner and 5L cash amount. It was mentioned in MOU that purchaser is giving 5L cash to the owner. Now after some days owner is not ready to execute the agreement for sale and even not returning the money. I don't have original copy of MOU, I only have true copy of MOU. Can this MOU be considered as legal document and can I ask my money back on the basis of MOU?
