@petermark0 I thought of my time in University and how much I learned when I was sharing an aparment for the first time, living away from my parents, and how caould I help my child realise how that feels / is before moving out.
As he is trying everything he can think of to move out being underaged, and I am responsible for his finances until he becomes 18, I exlained the "plan" to my lawyer and also to a social worker, to make sure I was not breaking any law (my sons father, who sees them few times a year and has pretty much no contact, has called social services on me a couple of times when he did not agree with how I am doing things and I feared my son will try to push me on this telling dad about it)
We did write the whole thing up, of course. After all, this is a contract, an agreement. And I tried to be as specific as possible (we all know teenagers, right= trying to find the crack on the rules to get what they want). We even specified what things we buy and share together (toilet paper, spices, cleaning products). I have had to show the "contract" a couple of times in this 7-8 months.
