What We Offer?

Representation in Civil and Commercial Litigation


We handle cases arising from breach or non-performance of contracts, payment claims, contractual and tort liability, as well as shareholder and business partner disputes. We provide full representation—from initial analysis through lawsuit, appeals, and enforcement.

Representation in White-Collar Crime Cases


We protect Clients' interests in cases involving economic crimes, such as fraud, breach of trust, forgery, managerial misconduct, and tax offenses. We represent both individuals and businesses at every stage of proceedings.

Supreme Court Proceedings


We prepare cassation complaints, responses, and other extraordinary appeals in matters requiring advanced legal expertise. We also assess the advisability and chances of success before the Supreme Court.

Insolvency and Restructuring Proceedings


We support Clients in crisis situations—from both debtor and creditor perspectives. We prepare petitions, assess legal and financial status, participate in creditors’ meetings, and review arrangement proposals and restructuring plans.

Enforcement and Security Proceedings


We manage judicial enforcement processes—cooperating with bailiffs, monitoring proceedings, filing asset tracing and security applications. We act early to secure our Clients’ claims—even before a judgment is issued.

Representation Before the National Appeal Chamber (KIO)


We advise and represent both contractors and contracting authorities in public procurement disputes. We draft appeals, responses, motions for interim measures, and represent Clients during KIO hearings.

Domestic and International Arbitration


We conduct proceedings before national and international arbitration tribunals. We advise on arbitration clause drafting, develop litigation strategies, prepare initiating submissions, and manage cases through to award enforcement.

Administrative and Administrative Court Proceedings


We represent Clients before public authorities (e.g., UOKiK, GITD, URE) and administrative courts. We prepare complaints, appeals, and cassation complaints, and advise on permits, licenses, and regulatory compliance.

Pre-litigation Negotiations and Settlements


We help Clients avoid lengthy and costly litigation. We conduct effective negotiations, draft settlement proposals, and protect Clients' interests in early-stage dispute resolution. Our goal is a swift and economically viable resolution.

We act decisively and strategically

With us, you know where you stand—and where you’re going

Litigation is not just a battle—it’s a strategy. That’s why we build an action plan from day one, based on solid legal analysis and a practical understanding of the Client’s position.
We represent effectively, but never blindly. Every decision is deliberate, and every step purposeful.
