The spouse with less money and income will be awarded maintenance in a divorce. The amount is calculated based on a statutory formula involving the salaries of both spouses plus the length of the marriage and, if there are minor children, the calculation factors in child support payments as well as support payments being made to children of other marriages, if any. You are entitled to half of the marital assets acquired during the marriage. Whether or not they were purchased with your salary, they are considered marital property.
