Its not a contempt matter at this point. You wouldneed to do an objection to the relocation and file a motion to restrain the move. There are very narrow time limits for this. I suggest you contact local Family Law counsel, as these can get complicated.
This post is not meant to be legal advice for a specific situation. Additionally, it does not constitute an attorney client relationship. It is always recommended that you consult with the attorney of your choice before taking action which can affect your legal rights.
Your daughter's mother is relocating your daughter to a new district. She is required to give you timely notice of the relocation. The above quoted part of the parenting plan is explaining how she must give you notice. You have 30 from when you received the notice to object to the relocation and/ or move to modify the parenting plan. There are 11 factors in determining whether or not a relocation will be allowed under RCW 26.09.520. The presumption is that the relocation will be allowed, but the objecting party can rebut that presumption. A relocation is grounds for revisiting the PP, so you may want to consider modifying in order to maximize visitations depending on how far your daughter is moving. Relocations do get complicated, and I strongly suggest you consult with a local attorney right away. I offer one free hour long consultations, as do many other attorneys. Feel free to call our office at 360-737-1492 if you want to schedule a consultation. Best of luck!
