Law firm Adico has sent the son a letter asking him to leave within six days if he wants to avoid the matter being taken to court, according to Italian media.
The father said: "We cannot do it anymore. My wife is suffering from stress and had to be hospitalised. He has a good job, but still lives at home.
"He demands that his clothes be washed and ironed, and his meals prepared. He really has no intention of leaving."
Should the son ignore the warning letter, the lawyers plan to file a protection order request on behalf of the parents against him.
