I'm so sorry you're going through all this. I think coastwitch gave you some good suggestions, but I wanted to counter a few things that firerobinrc0 said.
For the love of God, do NOT put your children's personal concerns into a jar to curse your enemies unless you want to curse your innocent kids. If you want to add feces to a curse jar, use dog feces.
Second, the Intranquil Spirit is called up to force a wandering lover to return, not punish enemies. You can read more about the Intranquil Spirit here and learn why it doesn't apply to your situation:http://www.luckymojo.com/intranquility.html
First and foremost, get yourself some Court Case products. The suggestion that firerobinrc0 said to put the judge in a honey jar to sweeten them toward you is a great idea. Burn brown candles on top of the jar dressed with Court Case oil. Also, you can always have the Missionary Independent Spiritual Church burn Court Case vigil candles on their altar for you if you want to know there is someone doing work on your behalf:http://www.luckymojo.com/honeyjar.htmlhttp://www.luckymojo.com/courtcase.htmlhttp://missionaryindependent.org/candle-services.html
Use Little John to Chew when you go to court by chewing a bit in your mouth during the proceedings (you can soak it in sugar water beforehand to make it easier to chew) and surreptitiously spit in your hand and rub that saliva on a piece of furniture or, even better, where the judge will walk.
Absolutely do protection work for your kids: http://www.luckymojo.com/fierywall.html
Let us know if you need anything else, and take care!
Thank you, St. Michael, St. Expedite and La Santisima Muerte!
