Hi all. My 18yr old son have just started a proper job. Where I mean proper I mean it's not cash in hand and on the books. He's still living at home and it getting his first pay on friday this wk (it's weekly pay through an agency). Do any of u charge your working children rent/lodge? I know as an adult now he needs to pay his way and it'll get him used to paying for things when he moves out. But I don't know how much to ask him for. How much do u lot charge? I'd love to let him live here rent free like he has for the last 18yrs but I know I cant do that now. My dad said I should say 25% of whatever he earns. But then I think a quarter of what he's earning seems a lot. Any help please?
