Custody involves determining which parent (or parents) should be involved in major life decisions, like religion, education, and health care. This can be shared (joint) or awarded to just one parent (sole). If you and your child’s other parent can work together and generally share similar opinions on these major life issues, then joint custody may be appropriate. However, in high conflict cases, agreeing to joint custody may mean you will need to return to court to fight for sole custody later on.
