I own a small shopping complex. A key tenant, who must give six months’ notice if they don’t renew their lease, has just given notice. I don’t have a problem with that, but with months to go before they exit they have now stopped trading. This will have a big impact on feet to the complex if they don’t trade and I’ve asked them to continue trading until they vacate the premises, but the client refuses and says he’s cutting his losses. Can I force him to trade for the remainder of the lease agreement?
