HOHL's expertise is acknowledged in the following areas of specialisation:

Several partners have law certificates in the following fields:

• private law;
• property law;
• estate and tax law;
• International tax law.

Several partners are also entitled to offer the use of collaborative law, which is a family law process intended to provide a "divorcing" couple, with an opportunity to resolve their "divorce" issues without an underlying threat of "going to court". The voluntary process is initiated when the couple signs a contract (the "Participation Agreement"), binding each other to the process and disqualifying their respective avocat's right to represent either one in any future litigation involving the "divorce issues".
