If you and your ex-spouse are not seeing eye to eye on child custody, and you have to go to court to fight over child custody, you need to get your documentation together before you start your custody case. The more documentation you have to submit to the court and have to rely on, the better off you will be no matter what is brought up during the court process.
First, you need to have a communication log that shows all the communications you have had between you and your ex. Every time you and your ex have a phone call, you need to write down the date and time of the phone call, as well as a summary of what you discussed.
If you sent a voicemail or received a voicemail, write down when you received it and a transcription of what was said. Keep a copy of the voicemail. Do the same for text messages, savings pictures of the screenshots of all communication. The same goes for emails.
Keeping a detailed communication log will help prove and establish what communication took place and what topics were not communicated. This will help prove what has transpired between you and the other parent.
Second, most parents who are dealing with a child custody case already have some sort of agreement in place. You need to keep a record that shows how that visitation is being respected. For example, you need to write down the date, time, and location where the child was exchanged.
On top of that, you need to document what you do during your visitation, even if it seems mundane. That way you can show what you do when your children are in your care. Write down the time they get up, when you take them to school, the activities they participate in, what you do together.
This will help show how you take care of your child and support their various needs. Family court judges want to see parents who support their children's everyday life, not just parents who show up for the big events or big vacations.
When it comes to going to court, you want to have as many records as possible that show how you take care of your child. Two types of documentations you should have are detailed communication logs and visitation logs. Work with your family law attorney to create documentations that show how you care for your child.
