My OH pays maintenance for his 18yo son. He doesn't have contact with him anymore but csa have told him that his son is attending college and the payments will continue until he finishes his course. Was just wondering when the payments stop as we thought it would be when he turns 18 but i've read somewhere it's either 19 or 20?! OH is not disputing that he has to pay, but the csa are not very helpful and don't tell you much. TIA
