Custody X Change makes life a little easier and less painful for divorced and separated parents and legal professionals.

We provide software that helps parents to:

  • Spend adequate time with their children.
  • Reduce conflict through better communication.
  • Create fair schedules that both parents are happy with.
  • Work toward parenting plans in the child's best interests.
  • Stay organized with the details of exchanges, notes and actual time-tracking.

Research methods

We strive for the utmost accuracy, with the goal of helping parents ensure the best possible future for their children.

Here's how we do it:

  • We research across national, state and county borders to understand the local custody processes.
  • We discuss and fact-check with professionals in varied roles: lawyers, judges, mediators, evaluators, parenting coordinators, family law facilitators, parenting educators, etc.
  • We dig through websites and documents from governments, courts and legal aid societies to extract the most important information.
  • We sit in on public custody hearings to observe procedures firsthand.

I found the software very easy to use. It's flexible, making a tough job with a tricky schedule easier to work out.
