Maj & Cieślak Law Firm

What Maj & Cieślak Law Firm does

Maj & Cieślak Law Firm (Maj & Cieślak Kancelaria Prawna Spółka Cywilna) is a privately held Polish civil-law partnership headquartered in Warsaw at ul. Grójecka 34 lok. 8, providing specialized legal advisory to entrepreneurs, corporate clients, and capital-market participants. The firm operates across nine documented practice areas: mergers, acquisitions, and corporate conversions; company law; contract law; intellectual property; investment and construction processes; power engineering and energy; securities and debt issuance; capital markets; and court, arbitration, and administrative matters. Its primary verticals are construction, energy (including renewable PV and storage projects), printing/creative industries, and capital markets, with additional exposure to corporate and IP matters for general business clients.

The firm is partner-led and relies on the credentials of its two managing partners. Grzegorz Maj (admitted 1987) leads M&A, privatization, and capital-markets work and is qualified to act as attorney before the Polish Financial Supervision Authority (KNF) and the Warsaw Stock Exchange. Monika Cieślak (admitted 2007) leads construction, energy, and printing-sector mandates and acts as litigator. The team comprises eight professionals in total — two managing partners, three attorneys-at-law, two trainee attorneys, one paralegal, and one administrative officer — with additional staff tenures documented as far back as 2011.

Commercially, the firm operates a classic professional-services model: bespoke engagement-based billing for legal advisory, transaction support, due diligence, contract drafting, and dispute resolution. It does not employ any proprietary technology platform or productized offering; its only digital assets are a bilingual (PL/EN) WordPress website (kancelariamc.pl) and a newsletter subscription channel. It is GDPR/RODO-compliant (policies effective May 25, 2018) and is not funded by external capital; ownership and management remain entirely with the founding partners, with no disclosed institutional investment, parent company, or M&A history.
