About us

Aabø-Evensen & Co is an Oslo-based boutique law firm within M&A and Capital markets.

The firm was established in 2002. Despite its young age the firm has a proven track record of delivering excellent quality legal services to major enterprises and institutions. The firms work, and especially its M&A focus, has received recognition by major M&A players.

We like to think of ourselves as a law firm that differs from others. We are not, and do not strive to be, the largest law firm measured by number of lawyers. Our goal is to be the firm of choice for clients with respect to their most significant business transactions. We have no intention of becoming a large firm. We aim to keep the flexibility and responses of a somewhat smaller firm and yet delivering big firm quality – or better.

Our working methods are highly effective, professional and service minded, including the use of some of the industry’s leading IT-tools for document- and knowledge management.

A client of Aabø-Evensen & Co can expect a high degree of partner focus on all levels of an assignment.

“My impression of law firm Aabø-Evensen & Co is undoubtedly positive. They explained everything, there were no surprises, the billable hours were regularly updated and explained, strategies were presented and discussed with us beforehand, there were no lack of resources and the time schedule was never exceeded. I believe what makes Aabø-Evensen & Co an excellent M&A law firm, is that they has previously, on numerous occasions, represented both sides of M&A transactions.”
