Our Approach

Strategic Advice

Clients don’t litigate just for the sake of it.  They litigate to protect and advance their business and personal goals.  Book Law keeps those goals in focus at all times.

Creative Solutions

Creativity is important to finding winning legal arguments, streamlining or finding alternatives to litigation, and reaching settlements, especially where there’s an on-going business relationship. Book Law always looks for creative options to achieve the best possible client outcome.

Client Service

Book Law tailors its services to meet each client’s needs, whether that means writing detailed strategy memos, sending brief emails or meeting in person to discuss the file.  Clients are always kept up-to-date on the status of their files and any important developments.

Cost-Effective Representation

Most of Book Law’s files are billed on an hourly basis, but clients are only billed for work that adds value, not for work that adds hours.  Book Law will also enter into alternative fee arrangements (AFAs), such as contingency fee agreements, discounted rates and fixed fees where appropriate.  Regardless of how the bill is determined, Book Law is always transparent about its fees.
