Is the threat something along the lines of "I went through hours to labor to bring you into this world and I can take you out of it just as easily!!"
Sorry, that's the one mothers use, or something like it. If there is clear evidence of a problem, file a motion to modify custody. You could call family services, but that may just get them out into the system, and not you.
no,unless the custody agreement states you cant move without notifying the court

No, if you are her guardian (you have custody) then she cannot do that until she is a legal adult.
Talk to a lawyer to avoid making an error that could jeopardize your custody.
Yes.
No. If the child's' mother calls the police you could loss custody of your child and possible go to jail. If I was you I would contact a lawyer who specializes in child custody cases. If you can get a notarized letter from the mother saying it is okay and giving you full custody.
If you mother has full custody, then yes. If both parents have custody, then no. If you are not emancipated, you cannot own property.
yes, but only if you have full custody. if its joint, then no.
yes, and file for custody based on custodial interference.
It will depend on many factors. Consult a lawyer. If you are worried the judge will move the child from you and give full custody to the father only based on him getting remarried, that is not how it works.
I suggest you get a local attorney where the jurisdiction of the divorce is that has a lot of experience practicing Family Law to see what the local court does in situations like yours. He/she should be able to answer all your question. My experience in OK is that it doesn't matter what the law says, the lower court judges don't follow it anyway. So you need to know what the local judge does.
Not with joint physical custody.
