I don't have to tell you anything

[wallababy]

my DH is having few problems with his ex and their son. They have been split for 8 years and for the most part things are fine, but she occasionally takes offence at something and uses access/information as a bargining tool/threat.
This time my DSS is having a bit of a rebellion/pushing boundries stage and she wants to take him to the GP, my DH (and I) don't think this is nescessary, but not against it enough to oppose too strongly, as it's not going to do any harm. However ex has now started saying that she doesnt have to tell him anything that is said, or keep him involved at all.

Surely this is wrong isn't it? (he does have parental responsibility as they were married)

Just what does he do if she starts witholding medical info, can he contact DSS' doctor (DH is not registered there, but does know which doc)??

The Doctor will probably not tell him anything.

Yes he can, though he might have to apply to the courts.

LucindaCarlisle, surely he has a right to know if his son is going to be referred or prescribed drugs etc??

titchy, apply to the courts for what? he has parental responsibility and is very much involved in all other aspects of his life (we have him every other weekend and one day in the week every week) including school etc.
It is just the EXW holding information for power.
