STBXH left us 3 years ago to move in with a work colleague. We live is Scotland and had a minute of agreement done.
It said he was to pay until he finishes full time education max 24 (DS is still in full time education and is likely to be for another 5 years ish..) Our DS turned 16 and I filled for divorce through the 2 years separated no children under 16.
STBXH said he doesn't need to pay anymore child maintance as I have made the minute of agreement nil and voild by applying for the divorce and once divorced he does not need to follow what it said.
Have I done the wrong thing? Can he really just stop paying? I'm gutted and don't know what to do.
