Dear Client,
In this situation, your liability as landlords for the loss of the old tenant's belongings largely depends on several factors, including the terms of the rental agreement, the specific promises made by your father, and the actions of the new tenants. Generally, landlords are not liable for the personal property of tenants unless there is a specific agreement or contract that provides for such a responsibility. In this case, if the new tenants were responsible for breaking into the trunk, they would be the primary parties liable for any theft. However, if your father made a verbal promise to the old tenant regarding the storage of his belongings, and if this promise was understood to be part of the rental arrangement, it could create a basis for a claim. To determine the validity of the old tenant's claim, you would need to verify what was in the trunk and assess the value of the items reported as stolen. To address the claim, consider collecting evidence of their value, investigating the genuineness of their claim and then offer resolution (if any).
