Chris Bosh committed a flagrant foul on an interior design company, hiring them to work on his fancy new Texas home with no intention of paying up ... according to a new lawsuit.
MJB Design Group claims Bosh and his wife, Adrienne, sought their help with the Texas project because they had worked with them already in Florida, where the firm is based.
According to the docs ... MJB entered into an agreement with the Boshes in January 2015 to provide interior design services and all materials for the Texas property until it was done, which was supposed to be in May 2016.
MJB claims this was all a sham ... because the Boshes dragged their heels during construction knowing it would never be done on time, but still promised them a paycheck.
The Boshes' home was not built on time and they backed out of their deal with MJB last month ... according to the suit.
MJB is suing Bosh and his wife for more than $2 mil -- a huge price tag for the NBA star whose playing days might be over.
We reached out to Bosh for comment ... so far, no word back.
