DISCLAIMER: You cannot rely on this calculation. Many parties are not entitled to any spousal maintenance, even if one partner makes more money than the other. This basic calculation does not take into affect assets, bonuses, trust income or earning potential of the receiving spouse. There are many different factors to consider. There is a standard threshold that needs to be met before anyone is entitled to spousal maintenance and you should review ARS 25-319 and seek the advice of a family law attorney. A party must meet the threshold test: Can you meet your reasonable needs? If the answer is yes, you may not be entitled to any spousal maintenance. The Maricopa County Courts will not allow such a calculation and judges vary widely on this issue. Since determining spousal maintenance (alimony) is not that simple, it is an issue that many parties try to settle instead of going to court.
