Although the formalities for the sale and purchase of real estate in France are best undertaken entirely through a notaire, authorised estate agents are permitted to process the sale and purchase contract (compromis de vente). The formal conveyancing (acte authentique) is then carried out by a notaire, on the terms set out in the contract.

In a case that was recently heard in the French court of appeal, a buyer brought a legal action for damages against an estate agent whom they considered had failed to undertake appropriate enquiries prior to preparation and signing of the contract.
