Your Landlord Cannot Just Keep Your Deposit, Here Is the Law
Tenants routinely lose money they are legally entitled to simply because they do not know the rules around deposit deductions.

At the end of a tenancy, a landlord may feel entitled to deduct whatever they see fit from a deposit. Many tenants, exhausted by the moving process and uncertain of their rights, simply accept whatever figure they are handed back. This is a costly mistake that landlords who operate in bad faith rely upon.
As a general principle across most legal systems, a landlord may only deduct from a deposit for damage that goes beyond normal wear and tear, for unpaid rent that is genuinely owed, or for cleaning that restores the property to the condition it was in at the start of the tenancy, not to a higher standard. They cannot charge you for repainting walls that were already faded when you moved in.
The Power of the Check-In Inventory
The single most important document in any tenancy dispute is the check-in inventory, ideally signed by both parties and supported by dated photographs. If your landlord did not provide one, that works in your favour: it is difficult to prove the property was in pristine condition at the start if no evidence of that condition exists. Always request a copy of the inventory and photograph every room on your first and last days in the property.
When you move out, ask for a check-out inspection and attend it in person. Request a written list of any concerns on the spot. If the landlord refuses to carry out an inspection or will not put deductions in writing, that itself is useful evidence if you later pursue a formal dispute.
Challenging an Unfair Deduction
Begin with a written letter or email setting out precisely which deductions you dispute and why, citing the check-in inventory. Keep the tone formal but firm. Give the landlord a clear deadline, ten to fourteen days is reasonable, to refund the contested amount or provide detailed written justification.
If they refuse, most jurisdictions offer low-cost dispute resolution through tenancy deposit protection schemes, housing tribunals, or small claims courts. Document every communication. A landlord who stonewalls in writing is building your case for you.
