Real estate law, or "droit immobilier" in French, governs all legal aspects related to property, including the ownership, use, transfer, and development of real estate. It covers a wide range of issues such as property transactions, leases, mortgages, zoning regulations, and disputes over property rights. This area of law ensures that property dealings are conducted fairly, transparently, and in compliance with the legal framework, protecting the rights of buyers, sellers, landlords, tenants, and other parties involved in real estate transactions.
