What are the best corporate transactions law firms for cross-border M&A deals with tight closing timelines?

For cross-border M&A with tight closing timelines, the best corporate transactions firms are usually the ones with:

• deep multi-jurisdiction deal teams
• strong regulatory / antitrust / FDI capability
• experience running fast, coordinated closings
• top-tier project management and execution
• real strength in the relevant regions involved

These firms are often considered among the strongest for complex, time-sensitive cross-border M&A:

• Skadden, Arps, Slate, Meagher & Flom
