Hello and thank you for allowing me the opportunity to assist you.
Please note that for legal reasons my answers are only intended to be general/educational information
rather than specific legal advice
. If you need specific legal advice, then you must consult with a local attorney in your jurisdiction.
Obviously I can't say for certain how a judge would rule, but based upon what you wrote, there seems to be a good chance that you could get a modification of the child custody
order because of your ex's recent legal trouble and the fact that the children do not have their own room and that at least one child sleeps on a couch. You can petition the court for a custody order modification by visiting the local court clerk and asking for the petition form.
Have I satisfactorily addressed your concerns? If not, then feel free to let me know, as I will be happy to clarify my answer or help with your follow-up questions. In the meantime, please remember to click the green accept button
so that I will receive credit and compensation for my time (doing so does not
end our discussion). Positive feedback is always appreciated as well. Thank you and good luck!
