My child's father has another child who is older and recently the mother of that child contacted me via email. She said he is still having trouble getting child support. My ex and I don't get along and rarely communicate but I have stayed clear of interfering with any part of his life outside of the legal issues with ds. And I certainly don't want to feel like I'm conspiring against him. So my questions is, should I help her out. I am getting child support for ds and I do know where he is living and who his employer is though I don't know the details. Federal government can be pretty broad.

I would be wary of getting involved here. Do you have any hard evidence that he is not supporting the other child? It seems unlikely that a man who supports one child without complaint would refuse to support the other, unless there was more going on.

In these days, it's not hard to track down a man with a job and settled lifestyle. She has the option of going to court and getting a support order.

Well I could see how it could be true because he stopped paying support to me when he quit his job. When he started working againg my CS office found him and started garnishing. But what was weird to me was that she said they are Facebook friends. If that's so, I would think that are cordial enough to discuss CS, therefore why would she contact me. In any case, I responded with a dummy address because as far as I know it could be her and him trying to conspire against me.

He is very angry at me for no reason. We recently had a trial for contempt (denial of visitation) and the judge dismissed it because he blatantly lied to the court about facts (dates which he visited with ds) that he admitted in a previous court trial. So I'm questioning the timing in all this as well.

I would stay out of it. Legally, it has nothing to do with you, and it sounds like a situation which could get messy.

Yes I will stay out of it. I just emailed back saiyng I was sorry to hear she was not getting child support and that I hope it works out.

I realize the dummy address is done, but it wasn't a good idea.
One way to put people off is to say 'I have been advised to (not get involved, communicate, etc.)'

... she said he is still having trouble getting child support. ...

He?

Do you mean "she"? I can't understand what you would mean if you are saying that your ex's other ex is telling you that your ex is not getting child support. He should be paying it, not "getting" it.
