The Richards Layton team has a unique command of Delaware corporate law, and trial lawyers who know the judges and have significant trial experience before the Delaware bench in both Superior and Chancery Courts. I’ve never worked with a more skilled and competent set of local counsel on a matter. Their experience in dealing with complex M&A related disputes is unmatched in the market.

Richard Rollo is one of the best trial lawyers with whom I have worked — period. His command of the factual record and legal issues at play in the case was remarkable, and his oral argument and case presentation skills are top-notch. I have worked with a great deal of litigators in Delaware, and he is the best. Going forward, when I have a need for local or co-counsel in Delaware, Rich will be the only lawyer I recommend to my clients.

The firm is highly respected. It is the best firm in Delaware and the oldest – the gold standard.

Rudy Koch is fantastic – a younger partner who does a ton of work and is known by the courts as a real litigator who knows his Delaware law. He is a superstar.

Blake Rohrbacher is a very smart lawyer.

Srini Raju is an alternative entity guy with tremendous gravitas, knowledge and great presence.
