Divorcing couples in Massachusetts can use a handy app to calculate alimony and child support payments and prepare a form for the court. Created by attorneys from the Infinity Law Group, the app will work with the iPad and the iPhone and costs $0.99. It calculates child support payments based on the state’s Child Support Guidelines. A date calculator is available to calculate the time for the court to issue a divorce judgment. This is a handy computer application but it should not be used in place of expert advice from an attorney.
