J.W. Hand, a justice of the peace in Denton County, ruled that Bank of America holds the title on the property in Flower Mound, the Fort Worth Star-Telegram reported. Ken Robinson, who has been living in the house for several months, did not show up at Monday's hearing and was given a week to get out.
"Any able attorney can sometimes beat an empty table every time, but you do need to prove your case," Hand told lawyers for the bank before they handed him their legal documents.
Hand said Robinson must post an $8,000 bond if he appeals the decision.
Chris Custard, a neighbor who had tried to get police to evict Robinson, was at the hearing and said he saw moving vans at the property during the weekend.
Robinson moved in last summer after paying a $16 fee to file an affidavit of adversarial possession. He also set up a Web site urging others to follow his example. Some people who have done so in neighboring Tarrant County have been charged with burglary.
The Flower Mound house was sold at a recent foreclosure sale for $400,000.
