I need to exactly when the rights of a tenant begin. Can someone suggest when the tenancy actualy begins ? Suppose someone has paid the seposit and signed the agreement from the tenants side and received te keys. However, the documents are not ‘executed’ yet and the countersigned copy is not in possession. In such a state does the person has some or full rights of a tenant ? What happens that within this short window if something happens and landlord changes his mind or something happens to the property ? Can the person claim part or full rights of a tenant ?
