Under US law, both parents must consent to a minor getting a passport. You can refuse to sign the application given your concerns. If the child already has a passport, you should immediately petition the court for an injunction preventing the other parent from taking the child oversees. However, you will need to support your concerns with valid evidence. You should consult a family law attorney to assist you.
Is there a court ordered visitation established? If there is not an order in place, you are not required to let the children go with their father at all and he would need to seek a court order to have any visitation with them. Even if there is a court order in place, generally speaking, you are not required to let him take the children if there is a risk of harm or bodily injury. You should contact an attorney in your area to discuss this matter further and to have any visitation order...
You may ask the court the continue the hearing so that you can retain an attorney. If you have previously asked for continuances the court may not be willing to grant it. However, the courts are generally willing to give the other party to the opportunity to get an attorney if the other side has one. If it is possible, you should try to retain an attorney by your hearing date.
I would advise attending the CMC unless you receive confirmation in writing from the creditor that the case has in fact been dismissed. If you do not receive it before the CMC both parties can notify the court at that time that the case has settled. The creditor will report the settlement to the credit bureau agencies and it should be reflected on your report in about 60 days after it is finalized. It would still show as a charge off on your report but it would indicate that it was paid...
If you failed to appear at your court date a warrant was most likely issued. You can contact the court clerk to get another court date to deal with the tickets. However you should contact a traffic attorney to to review the specifics and discuss with you how you should proceed given the warrants and financial liabilities you are facing.
I agree with Mr. Boss. I would add that if the discovery was sent after the summary judgment motion was filed, the deadline for your responses are likely not due until after that hearing. Thus, you will know whether the case is disposed of before having to prepare discovery responses. If not, opposing counsel is usually willing to give you an extension on the response deadline where a scheduled motion may make discovery unnecessary.
