Estimate spousal support amount and duration from income gap and marriage length.
Most guidelines start from the income gap and apply a percentage, with duration tied to marriage length. Marriages beyond twenty years often attract indefinite support in jurisdictions that retain it. Spousal support is far more discretionary than child support, and many jurisdictions have abolished formulaic approaches entirely in favour of judicial assessment.
