Sure you want to do everything under the sun to gain custody of your children but there will come a time when the court is actually going to make a decision. Right now, you need to accept this decision and you need to make the best of it whether you won or lost. Never forget that what matters the most is that the best interests of your child were put first. So if you do win your case, don't try to exclude your former spouse from your child's life.
Be gracious and respect any visitation rights that were granted to your former spouse. If, on the other hand, you lose, don't take this out on your child. You need to work hard at staying in your child's life as much as the court will let you. It is important to work hard at winning your child's custody case and then, once there is a decision, move on and make the best out of whatever happens.
When you are in the middle of a child custody case, it is critical that you maintain a very low profile. This means what you do and say to everyone; including your friends and family. You may injure your child custody case with even the slightest mistake. So when you're in the middle of one, you should take extra care about what you say to anyone. Old stories about your ex or anything that could be brought up later to hurt you should always be avoided. Your judgment may be tested when it comes to who you can tell what.
Do not take a rebellious attitude into the court system. Fathers, in particular, seem to think that the system is set up unfairly and that it is rigged against them. The point is not whether or not this is true; the point is that you will not help yourself if you go into court believing that the judge is against you. You need to work with the system as it exists now, not the way you want it to be.
Try to find a reasonable and practical approach to working with the system. You should work with a lawyer who can give you advice on this. If you carry a victim mentality with you, though, it is not going to help you with your child custody case.
To conclude, there is no such thing as a child custody situation that is pleasant, the only thing you can do is prepare for them as much as possible. This means that you need to do your research so that you can find out as much as possible about the local laws for child custody where you live. You also need to find really good legal assistance and actually follow the advice of the lawyer you hire. The above are some good basic tips to give you the best chance of winning your child custody case.
