What happens when the developer doesn't get the key after handing over the house?

There is no result. You can clean your room and get the key at any time. But your property right certificate needs you to take the house, pay the deed tax and maintain the fund before you can handle it. If you don't take over the house for a long time, you will have no property rights for a long time. The developer informs you that there is a property management fee for repossession.

As for Mr. Wu's concern, if he gets the key, it will constitute a "default" to the fact of delaying the delivery of the house, thus losing the doubts about the relevant claim. The lawyer on duty said that the receipt of the key by the owner does not mean giving up the right to pursue the developer's responsibility for delaying the delivery of the house, so Mr. Wu Can got the key with confidence.
