Calculation
Massachusetts: Massachusetts has statutory alimony categories and statutory limits for general term alimony. The amount of alimony generally should not exceed the recipient's need or 30% to 35% of the difference between the parties' gross incomes. Courts still consider statutory factors and may deviate where appropriate. New York: New York uses statutory guideline formulas for temporary and post-divorce maintenance on the payor's income up to the statutory income cap. The formulas are presumptive guideline calculations, but courts may adjust or deviate if the guideline amount is unjust or inappropriate after considering statutory factors. Maintenance above the income cap is discretionary.
Duration
Massachusetts: For general term alimony, Massachusetts uses statutory duration limits based on marriage length. For marriages of 5 years or less, alimony generally may not exceed 50% of the number of months of the marriage. For marriages over 5 and up to 10 years, the limit is generally 60%. For marriages over 10 and up to 15 years, the limit is generally 70%. For marriages over 15 and up to 20 years, the limit is generally 80%. For marriages over 20 years, alimony may continue indefinitely, subject to statutory termination, modification, retirement, and other rules. New York: New York uses a nonmandatory advisory duration schedule for post-divorce maintenance. For marriages up to and including 15 years, guideline duration is generally 15% to 30% of the marriage length. For marriages over 15 years and up to 20 years, guideline duration is generally 30% to 40% of the marriage length. For marriages over 20 years, guideline duration is generally 35% to 50% of the marriage length. Temporary maintenance lasts only while the divorce case is pending.
Modification
Massachusetts: Most alimony awards may be modified upon a material change in circumstances unless the parties validly agree otherwise. Retirement, significant income changes, or other substantial developments may justify modification under the statute. New York: Maintenance orders may be modified when statutory standards for modification are satisfied, including qualifying changes in circumstances. Separation agreements and judgments may contain additional provisions affecting modification rights.
