Custody Agreement vs. Parenting Plan

What is the difference between a custody agreement and a parenting plan? A custody agreement is usually two or three pages and addresses legal and physical custody, the child's primary residence, and a brief co-parenting schedule. A parenting plan goes into much more detail and addresses healthcare, education (schools, classes, tutors, special education), childcare/daycare, religious worship/training, detailed co-parenting schedules (daily, weekly, monthly, vacations, holidays, holy days), living situations (move-away, commuting, residents), sports (school/league/neighborhood), travel (permissions, locations, timing), financial (child support, tax exemption, add-ons), lifestyle (drug/alcohol/dating/sex) and much more.
