Our core expertise is advising on the full range of corporate transactions, including domestic and cross-border mergers and acquisitions, corporate reorganisations, amalgamations and restructurings, private equity, strategic investments and joint ventures.  We engage throughout the transaction cycle, from planning and implementation through to post-execution support.

Legal compliance is non-negotiable for any business. We provide advice on all aspects of Cyprus corporate law, including on issues relating to share capital and classes of shares, dividends, financing, share transfers and directors’ fiduciary duties.  And we advise on charges and their enforcement, share pledges, financial collateral and statutory compliance.  

We draft shareholders’ agreements and articles of association for private and public Cyprus companies.  We advise on all aspects of corporate administration and governance, including implementation and filings with the Cyprus Registrar of Companies and other public authorities.

We specialize in Cyprus and EU competition law and in advising on the related regulatory framework. We ensure competition law compliance in your business operations and advise on avoidance of anti-competitive behaviour, cartels, abuse of dominance and economic dependence cases.   We develop strategies to enable our clients to compete efficiently in both domestic and cross-border markets and ensure that their business operations are compliant with both the Cyprus and the EU antitrust frameworks. We combine high-level expertise with practical solutions that work for you.  

Merger Control

We have a strong track record on filing and clearing mergers, acquisitions and joint ventures with the Cypriot Competition Authority and the European Commission including foreign-to-foreign transactions where Cyprus domestic turnover thresholds are met.

We represent clients on a broad range of commercial and corporate matters including shareholders disputes, contractual disputes, debt recovery and enforcement proceedings.  Where appropriate we support actions by pursuing injunctive relief, such as asset tracing orders, discovery orders and freezing orders. We also act on the recognition and enforcement of foriegn judgments and arbitral awards.  


We act as counsel in domestic and international commercial arbitration, in international investment arbitration and energy charter disputes.    



We advise and act for clients on liquidations, examinerships, receiverships, debt restructuring and bankruptcies.  Our team has the track record necessary to give you expert advice in this complex and dynamic landscape. 

Our litigation practice supports debtors, creditors, liquidators, receivers, administrators, as well as bankruptcy trustees. We also act for creditors in actions brought against them for recovery of unfair preferences and other actions that may be taken as a result of insolvency.

We advise borrowers and lenders on corporate lending transactions; property development finance; debt sales and distressed lending and trading; debt and equity restructuring; receiverships and administrations; residual and other debt recovery and security enforcement.  

We are highly versed in the regulatory framework governing credit institutions, investment funds, financial services providers and credit-acquiring companies, advising our clients on all aspects from authorisation and licensing to on-going compliance and operations.
