Yes. You just need to have resided in Colorado for more than 90 days prior to filing (and minor children would need to have been here for more than 6 months in general). We offer flat fee uncontested divorces by a Colorado attorney starting at $795 if you would like help with the process, document preparation and guidance to ensure that you are getting the agreements right, are getting a fair deal and are getting done as fast as possible. I hope this helps.
