From the date the firm was founded in 1691 until 1976, it has had a succession of single partner practices. The year 1976 marked a change when Christian Lefebvre and Bernard Mennesson became partners and the firm changed from an individual practitioner’s office into a professional partnership, and at the same time became more involved in the business world. In 1994, the firm launched the name “LBMB”, under the influence of Jacques Beghain, then a new partner, who was a lawyer with prior experience in the industry sector. At the time we were one the first firms to have a brand and a logo. The logo was updated in 2016 but the brand and the values it embodies remain the same.
