This is a blog, not a question.

Where is this happening and what is the situation?

The only way to know if a Court will consider it alienation and not one parent or the other "unduly influencing the child" is to go to Court and ask. Some of this is the father reading and interpreting the mother's thoughts - and that will not work in Court.

Some of this is going to sound very petty if either party goes to Court. I would pick 5 specific examples and use those - if that is, in fact, what is going on here.

10 of us could say it is, but it is not, unless a court rules it is. Some of this is just normal hatred between exs

And in most a step parent is not liked and often attempts to restrict what a step parent can or can not do is done. Example, lots of court cases where one parent will go back so that a step parent is not the one watching the child, and the step parent has no say in the raising of the child.

So is there plenty of issues, yes, does this need to be back into court to clear this up, yes.

Is a lot of this, just every day issues in many custody battles, yep.
