A 30-year-old man has been ordered to vacate his family home by a judge after his parents sued to him for refusing to leave.

In a Onondaga County Supreme Court appearance on Tuesday local time, Mark and Christina Rotondo said they wanted their son Michael to move out for good.

The parents told the court they had gone to extensive lengths to coerce Michael to leave before filing the suit on May 7, including five written letters requesting him to leave and offering him $US1100 ($1450) to help him live on his own.

However, Michael, who has lived with his parents for eight years since moving back in when he lost his job, refused to leave.

“After a discussion with your mother, we have decided that you must leave this house immediately,” Mr Rotondo wrote to his son on February 2, according to reports.

“You have 14 days to vacate. You will not be allowed to return. We will take whatever actions are necessary to enforce this decision.”

The couple said that he does not pay rent or help with chores, and has ignored their efforts to help him move on and find a job.

Michael had tried to get the case thrown out on the grounds that his parents had not given him the legally required six months to leave.

Serving as his own lawyer, he also claimed he runs his own business and that living at home was “the overwhelmingly superior choice for [his] economic well being over the working of a full-time job”.

Asked about the details of his business, Michael said: “My business is my business”.

New York State Supreme Court Judge Donald Greenwood told the court enough was enough.

“I want you out of that household,” he said.

Michael told the court he planned to appeal the decision despite saying he wasn’t entirely sure what the judgement meant, ABC News reported.

“I’m not sure exactly how it ended it seems to me I should be provided 30 days or so. I plan to appeal it.”
