Illinois calculates maintenance with a statutory formula in many cases where guideline maintenance applies. The formula generally starts with a percentage of the payer's net income and subtracts a percentage of the recipient's net income.
Illinois also limits the result so the recipient's income plus maintenance does not exceed a set share of the spouses' combined net income. Guideline rules may apply only when the spouses' income fits within statutory thresholds and other requirements.
Duration is usually based on the length of the marriage, using a schedule that increases the support term as the marriage gets longer. Courts may still decide whether maintenance should be awarded at all before applying the formula.
Illinois maintenance rules are formula-based but not automatic. Courts may consider statutory factors and may deviate when appropriate. Use an Illinois calculator for planning, then consult a licensed Illinois family law attorney for case-specific advice.
