Knowing the warning signs and your legal options helps you act before small issues become big problems.
Warning Signs
Unfamiliar faces in the property, sudden changes in utility usage, or complaints from neighbours may indicate someone else is living there. Trust your instincts and investigate gently – often, early detection avoids conflict later.
Legal Remedies
Tenants who sublet without permission are breaching their tenancy agreement. Start by issuing a formal notice, and if the situation continues, seek legal advice. Court action may be necessary in persistent cases.
Tenancy Agreement Clauses
Clearly worded clauses about subletting are essential. Specify whether it’s allowed, the process for seeking approval, and consequences for breaches. Strong agreements make enforcement far easier.
Investigation Methods
Document your findings carefully. Check utility bills, communicate openly with tenants, and, where appropriate, consider professional property management or legal support to ensure you follow the correct process.
