What you want to ask is the old house bought in the countryside. My name is on the map, but my signature is not on the cadastral table. What should I do? The method is as follows:

1. Inquire about the ownership certificate: consult the relevant land management department or real estate registration department and ask for the ownership certificate. Official documents matching the information on the cadastral form will be provided to prove the legal ownership of land or property.

2. Obtain signature authentication: If you really buy real estate and want to show your signature on the cadastral form, you can consult the local land management department or the real estate registration department to understand the specific process and requirements.
