How to inquire about the commercial housing sales contract after filing?

All sales contracts are signed online. Before signing online, it is generally to initiatively confirm that the contract is correct and there is no objection, and then sign online. After the online signing of commercial housing, the developer records the contract, obtains the record number after being audited by relevant departments, prints out the contract text, and the buyer and the seller sign and seal, each holding its own copy. After the contract is signed, the real estate management department will return a record number after review, indicating that the contract has been successfully filed. You can log on to the local real estate market information network, type in relevant information, and inquire about the contract registration and filing.
