Practice Strengths


Our team guides clients through complex cross-border transactions including acquisitions, disposals, and joint ventures. O’Melveny’s London-based M&A lawyers have closed deals across industry sectors and continents, and they regularly team up with colleagues from our global network to ensure clients have access to the expertise they need.

Dispute Resolution    

Whether in litigation or arbitration, O’Melveny lawyers have handled disputes across a range of industries—including financial services, oil and gas, technology, and energy—and secured multimillion-pound wins for corporations and sovereign states. We represent clients in ad hoc and institutional arbitrations, and before the English High Court, often working with our anti-competition colleagues in the US, Asia, and Brussels to defend clients against competition law damages claims brought in the English High Court.


We help clients navigate investigations into potential economic crimes—and advise on internal policies that help ensure compliance with increasingly strict regulations. Representing clients in financial services and other industries, we have steered clients though multijurisdictional inquiries into alleged bribery and corruption, money laundering, and violations of economic sanctions and export-control regulations.

Capital Markets/USPP    

A market leader in private placements, our London capital markets team has advised on the placement of more than US$30 billion of traditional 4(a)(2) debt private placements by non-US issuers. Our private placement clients include FTSE 100 and FTSE 250 companies, as well as other global European-headquartered companies, across a range of sectors, including asset management, education, energy, financial services, manufacturing, pharmaceuticals, and real estate.

Aviation Finance

Our aviation finance team has represented aircraft and engine leasing companies, trustees, banks, and private equity investors on every aspect of the aircraft business, from financing and securisation to leasing and trading. With lawyers from our corporate, finance, and tax practices, the team delivers on deals that present first-time challenges and require a deep knowledge of the aviation industry.
