Divorce agreement modification needed?

Thank you for your question. The answer to your inquiry, of course, depends on three assumptions: First, that the child is still a minor. Second, that the child continues to live with your wife. Third, that our wife and her child have lived in Florida for six months. I would recommend your wife consult with a family law attorney in Florida to have a petition filed in the Florida circuit court to register and domesticate the New Mexico judgment. This will ‘make’ the judgement a Florida judgment, thus giving the Florida court jurisdiction going forward over any issues involving her child. She will need to serve her ex-husband in Oregon so she should have his address.  Good luck!
