Calculation
California: California has no mandatory statewide formula for long-term spousal support. Courts decide final support using Family Code § 4320 factors, need, ability to pay, marital standard of living, earning capacity, marriage length, and other circumstances. Temporary support is often estimated with county guideline formulas, including Santa Clara-style net-income calculations. 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.
Duration
California: For marriages under 10 years, courts often start with the assumption that support lasts about one-half the length of the marriage. For marriages over 10 years, there is no fixed duration assumption, and support may continue as long as one spouse needs support and the other can pay. Support may end by court order, written agreement approved by the court, remarriage of the supported spouse, or death of either spouse. 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.
Modification
California: Most support orders may be modified upon a material change in circumstances unless the parties validly agreed otherwise. Significant income changes, employment developments, or retirement may justify review. 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.
