In a case of tenant damage to property, the landlord's tort liability under Article 750 of the Civil Code is clear, but the burden of proof for damages is on the victim. In the absence of receipts, photos, valuations, and testimonies can be supplemented, but expensive artifacts and old items are difficult to assess objectively.

Kim Jeon-soo, a lawyer at Hanbyol Law LLC, recommends that in such cases, court appraisals by a court-appointed appraiser after filing a lawsuit should be used as a key means of proof. The court appraisal can play a crucial role in determining the objective value of the item and awarding damages.

As the appraisal process can be costly, it is advisable to collect evidence and prepare the application for appraisal with the assistance of legal counsel, keeping in mind that the court may determine substantial damages ex officio in accordance with the Civil Procedure Code and Supreme Court precedents even if the evidence is insufficient.
