At the end of a rental contract, there is always a complication about the deposit. Most of the time this is completely unnecessary, because the landlord has to prove that the tenant is not entitled to the deposit, according to article 7:224 lid 2 BW. The landlord must prove that the vandalism has been caused by you. This means the landlord must be able to show photos of the property before the tenant lived in the building and afterwards. In many cases a landlord cannot prove this, so you will soon be entitled to a refund of the deposit. Even when you have caused damage. The landlord must prove that you caused the damage.
