1. An MOU is at the most only a persuasive understanding document between the signatory parties and cannot be classified as a Contract or an Agreement, and hence CANNOT be registered and has nil legally enforceable value.
2. IF an MOU is registered in the guise of an Agreement, THEN it is legally valid perpetually till rescinded /revoked unilaterally, for failure to comply with the terms & conditions mentioned therein, by following due procedures of law.
