Court documents say Michael Rotondo does not pay rent or help with chores and has ignored his parents’ offers of money to get him settled.
Despite doling out five eviction letters, Christina and Mark Rotondo say their son still refuses to move out.
Michael is arguing that legally, he was not given enough notice to leave.
The would-be empty nesters’ lawyer, Anthony Adorante, told Syracuse.com the couple did not know how else to get their adult son out of their house.
“We have decided that you must leave this house immediately,” reads the first letter, dated 2 February, according to court filings.
When Michael ignored the letter, his parents wrote up a proper eviction notice with the help of their lawyer.
“A legal enforcement procedure will be instituted immediately if you do not leave by 15 March 2018.”
The couple then offered their son $1,100 (£819) to move out – along with some sharp commentary about his behaviour.
“There are jobs available even for those with a poor work history like you. Get one – you have to work!” they said.
In April, Mr and Mrs Rotondo went to their local town court to see if they could evict their son.
But they were told that because Michael is family, they would need a Supreme Court justice to officially send him packing.
According to WABC News, Michael has called his parents’ lawsuit “retaliatory” and has asked the court to toss out the request.
