For example, Illinois law uses the terms “granting of parental leave” and “granting of parental responsibility” instead of custody. Parents should always consult a family law expert in their country when they have questions about national laws governing co-parenting after divorce or separation. Shared custody describes a defined scenario in which each parent spends at least 40% of the time with the child over the course of a year, either through physical custody or access. Both parents have financial responsibility and both make all important decisions together, even if the child lives primarily with one parent. Under Canadian law, custody does relate to who is responsible for deciding matters that concern the child. For example, a custody agreement may order a co-parent to have sole custody, while ordering joint physical custody of the child. The notion of shared custody can be one of the most confusing. This is often confused with shared custody, but they are not the same. Shared custody is actually a concept defined under the Federal Child Guidelines (CSG) that refers to the financial obligations of a child`s parents, not decisions. .
