The lease granted to a prospective tenant

Practical application:

Under this case law, the baker's lease is a commercial act, so its proof against the café does not require a fixed date (date certaine) from registration. The baker can enforce his earlier lease against the later tenant even without registration. He should formally notify the café and landlord of his priority, ideally via a bailiff's notice (huissier), and if necessary, initiate legal proceedings to maintain possession. Keeping the original signed lease and all correspondence is crucial.

Practical application:

Because the florist's lease is a commercial act, it is enforceable against the boutique without a fixed date, giving the florist priority. The landlord faces potential liability: the boutique can claim damages for failure to deliver vacant possession (obligation de délivrance) and possibly seek annulment of their lease. The landlord should negotiate a buyout of the florist's leasehold rights (droit au bail) or compensate the boutique for its losses to avoid litigation.

Practical application:

The restaurateur's timely registration does not grant priority over the bookshop's earlier lease, as the bookshop's lease is a commercial act not subject to the fixed date rule. The restaurateur should put the landlord on formal notice to resolve the conflict and provide vacant possession. If the landlord cannot, the restaurateur may terminate his lease for non-performance and claim damages, including reimbursement of registration costs and lost profits. Consulting a French real estate lawyer promptly is advised to enforce these rights.
