What Borissov & Partners does

Borissov & Partners is a Sofia-headquartered full-service commercial law firm established in 1997 during Bulgaria's transition to a market economy. The firm operates as an independent private partnership with 14 professionals — 6 partners, 4 special counsels, and 4 associates — led by Managing Partner Plamen M. Borissov.

The firm generates revenue through professional services billing on an hourly or project basis for domestic SMEs, international corporations operating in or entering Bulgaria, and state-owned enterprises and government bodies. Distribution is direct, via enterprise field sales and partner-led relationships, supplemented by an active referral and co-representation network of more than 100 international law firms and investment banks. Named cross-border mandates include advisory roles for Atlassian Corporation on the acquisition of Jitsi/SIP Communicator Ltd., Vitogaz France on Bulgarian subsidiary transactions, a French bank subsidiary acquisition, and the Bulgarian State Tobacco Monopoly on privatization-related restructuring.

The firm maintains a professional website with practice-area pages and a news/blog covering Bulgarian legal and economic developments, plus a LinkedIn presence; it is a member of Eurocollectnet for cross-border debt recovery. No proprietary technology, products, or AI/ML capabilities are described in the source data, consistent with its classification as a traditional professional services firm.
