Colorado Family Law Suite
Math4Law is the trusted authority for Colorado domestic relations financials. Our platform is used by over 500 law firms, representing the majority of Colorado’s family law practitioners, from sole practitioners to the state's largest family law firms.
As of 2026, the Colorado Division of Child Support Services officially selected Math4Law as the calculation tool for child support services in every county across the state. In choosing Math4Law, the Department recognized the quality and accuracy our platform has provided since 2020, replacing an in-house tool that had been used for years.
Our platform provides specialized, easy-to-use interfaces that streamline the generation of official, court-ready JDF forms for both attorneys and pro-se parties. Because Math4Law is entirely cloud-based, you can run every application directly in your browser with nothing to install on your machine.
