Should the property company recover the arrears from the original owner before the property fees owed by the original owner are paid off?

According to the "Measures for the Administration of Property Charges", when the property right is transferred, the original owner shall settle the property service fee. A new property service contract relationship is formed between the property and the new owner. The property should claim the fees owed by the original owner from the original owner, and the new owner will not bear joint liability for this. Therefore, the law does not require the property company to recover the arrears from the new owner. Before the new owner bought this house, he did not enjoy the services of this property management company. The property company should ask the original owner to pay the fees owed by the original owner for enjoying the property service. It is the responsibility of the property company to verify whether its property fees and other expenses have been settled when the original owners move out of the community. However, the property company did not do so, but in the case of default, let the original owners "fuck off." Property companies should urge the original owners to pay the arrears. In reality, some properties have encountered a similar situation, that is, the owners who owe money have moved away, and the property can't find anyone at all, so it can only be solved through legal channels. The new owner can help the property company find the original owner to pay the arrears, but he is not obliged to pay in advance. The property management fee is based on the contract between the property management company and the owner, and the property management company should not transfer the arrears of the original owner to the new owner.
