Calculation
Georgia: Conservative educational estimate based on need, ability to pay, income disparity, marriage length, marital standard of living, earning capacity, financial resources, and Georgia statutory factors; no mandatory statewide formula applies. Illinois: Illinois uses statutory maintenance guidelines after the court first decides that maintenance is appropriate. Maintenance is not automatic. If guideline maintenance applies, the amount is calculated from the parties' net annual incomes, and the recipient's income after maintenance may not exceed 40% of the parties' combined net income.
Duration
Georgia: Georgia has no fixed statutory duration formula. Temporary alimony may apply while the case is pending. Post-divorce alimony may be periodic, lump sum, short-term, long-term, or reserved depending on the facts. Longer marriages and greater economic dependency may support longer awards, but duration remains discretionary. Alimony may terminate or be modified according to the order, agreement, remarriage, death, cohabitation rules, or changed circumstances where applicable. Illinois: Illinois uses statutory duration multipliers based on the length of the marriage at the time the action is commenced. For marriages under 20 years, the duration is calculated by multiplying the marriage length by a factor that increases with marriage length. For marriages of 20 years or more, the court may order maintenance for a period equal to the length of the marriage or for an indefinite term.
Modification
Georgia: Periodic alimony may be modified upon a material change in the financial circumstances of either party. Courts evaluate whether the change is substantial enough to justify adjustment of the existing order. Illinois: Maintenance may be modified upon a substantial change in circumstances unless the award is expressly non-modifiable. Courts review financial developments, employment changes, retirement, and other relevant factors when evaluating modification requests.
