I have a child with my ex and he has an 18 year old who lives with him but is off to uni in September. He has no other children at home.
He's never changed the amount on the standing order when it's changed and I've not bothered to chase it as it's only a few pounds.
Does the amount change once the child at home is an adult/18/at uni?
He has no contact with our son and we are not in touch.
