About TK

Enabling you to go further


Teekens Attorneys was founded in 1949 by Mr. Michaël Teekens. In 1955, Mr. Willem Frederik Karstens founded Karstens Notaries. Teekens Attorneys and Karstens Notaries operates as TK since 2001.

In order to optimise our service to the client, we moved into a joint office in 2006. Our next step was to become the market leader in the Rijnland region. A law firm’s ranking in the market is determined by its expertise and the quality of the service it provides.

Quality and service

We made substantial investments in our expertise and know-how to safeguard our high quality of service. We also entered into partnerships with universities. Since 2006 the firm has also experienced significant natural expansion. In 2009 and 2010 TK won the Golden Hourglass award for the fastest growing firm over the previous 5 years. In 2010 we became the top law firm in the region, making us the obvious alternative to the firms in the South Axis district of Amsterdam. We offer the same high quality as well-known national firms, but our fees are lower. In addition, TK is an open, approachable and flexible firm, with an easily accessible location.


TK is known for its extensive international experience and involvement, which resulted in the specific international organisation structure known as TK International.
