I think your case will really hinge on what you and your ex have hiding in the closet, if you know what I mean. If your past is sprinkled with criminal charges, arrests, history of violence, neglect, or any such issue, you could really be fighting a losing battle. If the case is just a matter of he said-she said, you'll probably have a better chance. There are many legal positions you could take on your case. I think there is merit to what KTM said about taking the deal then following up with a motion just so you could start seeing your kids. The longer you go, the worse it is for them and you. As a matter of right, everyone is legally due a custody trial anyway. So, you could take the option (I assume you still can), and you can follow that up with mediation. However, after custody is settled, you must demonstrate a "change of circumstances" in order to change custody. Some of these factors are black/white, others are more subjective and a creative attorney can make about anything work. If you think this case is just going to get drug out more and more, you may be best to take the deal to get your kids, and go from there. It also hurts your ex's case that you are abusive and a terrible father if she is offering to give you the kids. If she was so concerned about your abusive nature, why would she offer that deal?
I'm assuming this deal was offered verbal? If so, I'm not surprised. Send a letter to try to get that deal in writing. Then you have even more for your upcoming trial. You can simply say something like "when you offered to give me parenting time for a few hours a day in court the other day, what days did your client have in mind? I believe its important for the kids to spend time with me. Please advise which days your client was considering, and what times."
Your listed points for shared custody, to me, are not good ones. Most parents I talk with are upset and spend way too much time bashing the other parent and nearly no time bolstering their own abilities and benefits to the kids. As such you come off looking more like a vindictive, upset parent instead of a good-hearted, level headed, and reasonable parent.
I think your reasons should look more like:
- I've traditionally been the parent to take the kids to school, and my schedule is flexible enough to do that. I love to do it.
- I used to play soccer and had started working with my daughter to play soccer. She now cannot share that time/bond with me.
- I am a stickler for the rules and honesty. I want to make sure my children are brought up with the same values. Its important to me.
- My son is old enough, that he needs a positive male role model. Without a consistent role model. I've always been there for him, and now that has been ripped away, leaving him deprived.
You see how these statements nearly always start with "I" or deal with "me?" When you spend so much time focusing on how bad the other parent is, you forget how important your role is. Don't lose sight of that.
