Calculation
Ohio: Ohio has no statewide mathematical formula for spousal support. Courts decide whether support is appropriate and reasonable by considering statutory factors, including income, earning ability, age, health, retirement benefits, marriage duration, standard of living, education, assets and liabilities, contributions to the other spouse's earning ability, lost income capacity, tax consequences, and any other relevant equitable factor. Pennsylvania: Pennsylvania guideline spousal support and APL are typically calculated using net-income percentages: 33% of payer net income minus 40% of recipient net income when there are no dependent children (25%/30% when dependent children are involved). Post-divorce alimony has no mandatory formula and instead requires courts to balance statutory factors under § 3701.
Duration
Ohio: Ohio has no fixed statutory duration formula. Courts may order support for a defined term, indefinitely in appropriate long-marriage or dependency cases, or not at all. Duration depends on the facts, including marriage length, earning capacity, age, health, retirement prospects, standard of living, and whether the recipient needs time to become self-supporting. Support generally terminates at death unless the order provides otherwise, and may also terminate or be modified under the terms of the order. Pennsylvania: Pennsylvania has no fixed statutory duration formula for post-divorce alimony. The court determines duration as reasonable under the circumstances and may order alimony for a definite or indefinite period. Spousal support and alimony pendente lite generally last only during separation or while the divorce case is pending.
Modification
Ohio: Spousal support may be modified only if the court retained jurisdiction to modify the award and a substantial change in circumstances has occurred. Income changes, retirement, disability, or other significant financial developments may justify modification. Pennsylvania: Most Pennsylvania alimony awards may be modified upon a substantial and continuing change in circumstances unless the parties agreed otherwise. Courts evaluate financial changes affecting need, ability to pay, or overall fairness.
