The final version of this page is at https://atharkhan.com/blog/understanding-timeshare-and-custody-in-california-family-law/ ## Working notes A percentage describes time or responsibility over a defined period; a custody label does not supply that percentage. [[Cal. Fam. Code § 4055]] uses the approximate time of primary physical responsibility in the support formula. Review school days, holidays, exchanges, and the actual arrangements before converting a schedule to a percentage. [[Guidelines|Guideline]] calculations for [[Child Support|child support]] also depend on [[Income|actual income]] or [[Imputed Income|imputed income]]. Keep the parenting order and the support calculation distinct.
