A: Unfortunately, right now and for the near future, the courts are pretty much closed for most business. You can file your motion for contempt, however, it will not be heard any time soon. My suggestion is that you take her up on that offer and go there as often as possible. Maybe if you go too much, she won't like the inconvenience and finally let your daughter go with you.
A: You can file a "partition action" in the superior court. The court will most likely force the sale of the property at a reasonable price. You will need to retain an attorney who practices real estate litigation law.
A: You need to file a motion with the court requesting an educational support order post-judgment. If you have an agreement then it must be put in writing and signed. Once you do that you can go to court and have it made a court order when the motion you filed comes up on a calendar. If you don't know how to go about filing and serving, etc., go down to the court service center or the clerk's office in your district and they will show you what to do. If you don't have an agreement then you will both have to go to court on the court date and see if family relations can assist you, otherwise you will have a hearing. You both will need to fill out financial affidavits.
