Columbia Title Company, which has provided title services in the Tri-Cities and Walla Walla for more than a century, has been sold to TitleOne, an Idaho-based title and escrow provider whose parent company is tied to a global real estate and relocation services firm.

TitleOne is a subsidiary of Realogy Title Group LLC, which provides title and escrow services in all 50 states and Washington, D.C.

Realogy is in turn a holding of Realogy Holdings Corp., (NYSE: RLGY), which operates globally.

Columbia Title was first established in 1889 as Dean McClean Abstract Co. It currently operates  offices in Walla Walla, Dayton, Kennewick and Prosser, which will convert to the TitleOne name.

Its 20 employees will retain their positions. Ben Case, owner of Columbia Title, will manage the Walla Walla operation.

Terms were not disclosed.

TitleOne is a fast-growing Idaho firm that is branching west to Washington. It formed in 2000 and has statewide through the successive acquisitions, starting with Idaho Title and Trust in 2011.

The addition of Columbia, Benton, Franklin and Walla Walla counties in Washington expands its reach to 19 locations and more than 300 team members.

“Columbia Title Company is the perfect fit for TitleOne in terms of geographic desirability, rich history and greater customer service. Adding Columbia Title Company to the TitleOne family will expand our servicing capability into the state of Washington, with four new locations and the addition of an outstanding team,” Jason Vickrey, president of TitleOne, said in a press release.
