Divorce dilemmas of a child

That's what lawyers, not children, are for. It isn't your responsibility to help anyone "win" or "lose".

I'm sorry your parents are divorcing and I hope that you can remain on good terms with both of them.

Let me say this from experience.

Don't go there.

I don't know the specifics of your situation, but I do know that being in the middle of a divorce is a bad experience for a kid. Parents with any decency will do whatever they can to keep their kids out of it.

My advice to you is to keep from being in the middle of a fight that isn't yours.

I believe the best advise have already been made.

The court will hammer this out.
Financial help for your support is set by the court and is based on the information your father gives to the court, like sources of income and owned property.

It is not unusual for spouses to hide sources of money from each other, but if the court finds out about it, then action will be taken.

Apparently you have information about your father's financial affairs. Stay out of it, unless your mother is suffering financially. SHE has to make claims on any additional income she needs.
