Good-- so now you have two charts to work with. I am not sure why you deleted the outer planets in your second chart, as they give additional information. If you've got enough astrology background to do this, you can compare them. May we assume that the plaintiff is the child/ren's mother? Probably she is symbolized by the moon. Children are a 5th house matter. See what is happening with the sign ruler: moon in the filing chart; and Mercury in the court date chart. Litigation and open enemies are a 7th house matter, and so on.
What sorts of movement, if any, do you see taking place between the filing date and the court date?
Then how do these charts compare in synastry or a composite chart with your chart? In your chart, the sun gives the core identity; and it is one significator of the father (you) in a day chart, which both of these are.
In custody matters, the judge must (by law) consider what is in the child's best interests, so see how that plays out in the charts and for you personally.
I don't know whether or not you have (or think you can afford) a lawyer, but it is not advisable, if not, for you to do this without one. Some law firms do pro bono work; and there may be a Legal Aid Society near where you live.
Unless dad is some type of abusive monster (which you are not) or a serious addict, children need a good relationship with him for their own best emotional development.
You might also post a simple horary question, something not-to-vague yet a single-issue question, such as "Will I retain (or lose) my current child custody arrangement?"
