Ask the landlord in writing why the deposit is being withheld and request an itemised statement, receipts and any relevant photographs or inspection records. A landlord may seek deductions for issues such as rent arrears, unpaid bills or damage beyond normal wear and tear, but should not retain money without a reasonable basis. Keep your tenancy agreement, payment records, photographs, messages and evidence of the property’s condition. If you cannot resolve the matter directly, you can apply to the RTB for dispute resolution; the outcome will depend on the facts and evidence in your case.
