I bought a property right house in the village without knowing it, but I can't get the property right certificate. What should I do?

Sue the developer to cancel the contract and return the purchase price. According to the Consumer Protection Law, consumers should have the right to know when purchasing goods. If they buy the property without knowing it, they can sue the developer to cancel the contract and return the purchase price. The real estate license refers to the certificate that the purchaser obtains the legal ownership of the house through the transaction and can exercise the right of possession, use, income and disposal of the purchased house according to law.
