The previous property matters have not been resolved. Who should pay the current and previous property fees?

If it is a property enterprise exchange:

After the new property management takes over, the owner shall pay the property management fee to the new property management company according to the property management contract.

The original fee in arrears depends on whether the creditor's rights of the property management fee are transferred. According to the contract between two property companies and the owners' meeting. If the contract stipulates that the original property management company will transfer the creditor's rights (unpaid property management fees) to the subsequent property management company, then the owner must pay. If there is no agreement in the contract, the original property management company still reserves the right to recover the property management fee from the owner (it may not be performed).

Therefore, you should ask the property management company to provide relevant written proof of the contract, otherwise you should not pay hastily. Because the original property company can charge you twice as much.
