So we had our hearing today and were successful in claiming our full deposit + 3xdeposit + court fees + costs.
Our landlady had issued a cheque for the deposit which arrived shortly before the hearing. There wasn't time for the cheque to clear (given the trustworthiness of our landlady!) and so we went through with the hearing. I was concerned the judge may find that the deposit had already been returned but he made the order to state that the full deposit must be returned, with credit offered by the claimants for moneys already received. That way if the cheque goes through it has been upheld, if it bounces then we still have a judgment to be enforced
Excellent news. She was just playing the classic strategy of trying to steal your money with the hope you'll just roll over and take the abuse, and if you don't, she'll just repay it - no harm done. It's fantastic that the thieving scum didn't get away with it.
A lesson for us all. Pursue them.
