Contracts between landlords and tenants are created for a specific purpose, and when the contract has been breached, you have to take action. Chasing up outstanding rent is one of the most common breaches, and it’s important that you deal with this problem quickly as a landlord.
Outstanding rent should always be responded to with a letter. Simple stating the amount of money owed, while you should always include the threat of court action. In most cases arrears will be cleared shortly after, and you should always follow up on your word if payment is not made.
You could also say they need to contact you urgently, and it’s all about gathering written proof to back up your contract, proving that the tenant has breached the contract and not responded. The court will then take the necessary steps to get your money back.
