How do you find out if someone owns property in France?

To find out if someone owns property in France, you can check the French land registry, known as the "cadastre," which provides information about land ownership and property details. Additionally, you may contact the local notary ("notaire") who handles property transactions, as they maintain records of property ownership. In some cases, you might also access online databases or inquire with local authorities for specific ownership information. Keep in mind that privacy regulations may limit the availability of this information.
