Commercial Leases

As a technical discipline in constant evolution, commercial leases cannot be apprehended without a recurrent practice enriched by a permanent legal monitoring.

Bertrand de LACGER, author of numerous articles in the Rent Journal and commercial lease practitioner since 1999, assists his clients, landlords or users, French or foreign, at any stage of the life of the commercial lease, in advice and in litigation .


While model deeds can be found on the Internet, the stakes, the complexity of commercial lease law and the risks of requalification or invalidity require the intervention of a qualified professional with proven experience in this discipline, who alone can ensure the legal security of the parties and third parties.

The tasks usually entrusted to the LB AVOCAT firm include in particular:
