The Accounting Firm Built for Law Firms.
Founded and led by an attorney and CPA, we proudly provide financial clarity, compliance, and strategic support to law firms and their leaders.
We understand law firms, we understand accounting, we speak your language.
We help legal professionals and firm owners navigate trust accounting, compliance, and day-to-day financial management with complete confidence. We won’t just manage your books, we’ll strengthen your firm’s foundation.
Here’s how we do it:
When you’re a legal professional, precision in your expertise is non-negotiable. We think your accountant should have this too.
I’m Knight Lancaster
I’ve been on both sides of the legal and financial desk, as a practicing attorney and as a CPA. It means I speak your language, understand your obligations, and anticipate the pitfalls that generalist accountants can miss.
Why law firms choose Lancaster CPA
Our clients benefit from a CPA who sits confidently at the intersection of financial accuracy and legal insight.
That’s why firm leaders across the U.S. trust us with what matters most: compliance, accuracy, and strategic clarity.

Adding Knight’s services to our operations has been tremendously helpful in streamlining our accounting, bookkeeping, and financial functions. Further, having Knight as a resource has been extremely valuable for strategic planning regarding big-picture financial outlook decisions as well as streamlining day-to-day business and accounting functions. The accuracy of Knight’s and his team’s work has been outstanding and is a huge improvement over our previous “DIY” approach. Knight has enabled us to focus more on the legal work we want to be doing and essentially outsourcing what used to be accounting and financial headaches.
