The property management company subcontracts cleaning to other companies. What if the residents accidentally fall down?

The legal relationship should be clear that the property is the management of the whole community, and the property company can be required to pay fees. Because the property company and the cleaning company have a contractual relationship, they can ask the cleaning company for compensation again, but the most important thing is that you should provide evidence that your fall is directly related to property management or mainly caused by the negligence of the property company.
