In divorce law, there are two ways of settling a post-divorce parent-child relationship.
In 'Sole Legal Custody', one parent is granted the exclusive authority to make significant decisions for the child, such as education, healthcare, religion, and so on. The non-custodial parent typically has limited or no say in these decisions.
In 'Joint Legal Custody', parents are granted the authority to make such decisions and financially contribute together, albeit one parent not being physically together with the child. Joint Legal Custody still set exceptions where a parent would not be granted custodial rights, such as previous history of physical/verbal abuse.
