Attorneys

For more than 50 years, Blatter Seynaeve has advised, defended and trained its clients on the complex legal issues arising from real estate transactions and leases of all kinds (commercial and professional leases in particular).

A true French institution in the field of commercial lease law, the Blatter Seynaeve name is synonymous with technical excellence, unanimously recognised by its peers and clients, and with extensive practical experience across a wide variety of economic sectors: luxury retail, mass retail, real estate development, banking, insurance, publishing, advertising, industry, etc.

Jean-Pierre Blatter has brought together a group of lawyers specialising in real estate and lease law, with the aim of providing highly technical guidance that combines knowledge, pedagogy, anticipation, imagination and strategy, qualities essential to the players of a constantly changing real estate sector.

To fulfil their mission, the firm’s lawyers aim to be attentive advisers as much as committed litigators.

Their commitment is to anticipate in order to prevent disputes, to define a strategy and to draft with rigour the deeds that seal agreements and contracts. In litigation, Blatter Seynaeve strives to establish and protect its clients’ rights, to build the solution to the case and set it in time, to plead, settle and conciliate where appropriate, in order to succeed. In this spirit, the firm constantly involves its clients in the choices to be made and keeps them informed of developments in their cases.

Where tradition

meets modernity

   Once laws are drafted, they remain as they were written. Men, by contrast, never rest; they are always acting.   

Portalis

Real estate law, and lease law in particular, is one of the fastest-changing areas of French law. Little codified at the outset, it is constantly reshaped by the legislature and the courts, and grows ever more complex.

Working in real estate calls for the support of a specialist who masters both the substance of the subject and the aims of the legislature, in order to meet clients’ expectations.

From the outset, Blatter Seynaeve has combined a theoretical and a practical approach, making its extensive doctrinal work an essential pillar of its hands-on support, with two key commitments: clarity in each of its solutions and pedagogy towards its clients.

01

A diverse client base

Very large French and international companies, CAC 40 companies, listed and unlisted real estate companies, investment funds, banks and insurers, public companies and local authorities, property and asset managers, as well as private landlords and tenants, make up the firm’s regular clientele, which values its availability and its scrupulous respect for professional ethics and business confidentiality.

Engagements

Embracing a perspective of anticipation and long-term management.

Responsiveness

Responding with the speed that business life demands.

All partners are certified specialists in real estate law and in commercial and professional leases.
