Domestic Partnership - ex-spouse relocating with children

Looking for advice on a legal issue. Here's what happened.

ex-spouse relocating with children. I've been dealing with this for about 14 months now and the situation isn't improving.

What are the risks if I pursue this? What's the likely timeline?

NAL, but from what I've read, you should send a written demand. But don't just take my word for it, get real legal advice.
