Non-custodial parent bought a house and took a roommate to offset mortgage expense. Roommate pays $600 per month in rent, has his own room, and run of the house. To my knowledge, there is no rental agreement, and the money is under the table.When confronted with evidence of the rental income, other parent's response is that the roommate will move out a week after the projected hearing date. It is clear that roommate has been paying rent for 7 months. Further claims that only $400 is rent...the other $200 is roommates share of utilities. Both claims seem silly to me, but I'm not a judge. Do they have merit?
