Avvo has agreed to be acquired by Internet Brands.

California-based Internet Brands will be adding Avvo to a collection of other legal websites that it operates, such as Nolo and Martindale-Hubbell. Internet Brands’ portfolio also includes companies such as eDoctors, CarsDirect Connect, and WebMD.

Avvo began in 2006 in Seattle, Washington. The company counts more than 300,000 attorneys as active users of its services, according to a recent press release.

The financial terms of the acquisition were not disclosed.

Avvo CEO and founder Mark Britton will continue his role as the head of the company and Avvo will keep its name and continue operating at its headquarters in Seattle after the company is acquired by Internet Brands.
