If sole custody means that one parent has complete power, joint custody is a 50/50 share. Joint custody is a very typical arrangement in which parents share equal responsibility for their child's well-being. This requires them to collaborate in order to agree on timetables, choices, and other shared duties. For example, if one parent wants the child to have a hockey game on Saturday but the other doesn't want this conflict to occur, they would need to come to an agreement about it. In some cases, depending on the province or state, judges may award primary custody to one parent based on what is called "best interests of the child" evidence. These categories are not fixed, so courts will consider all the circumstances of the case when making their decision. For example, if the parent with custody cannot provide a stable home environment for the child because he or she suffers from alcoholism or drug addiction, this might be considered by a judge to be detrimental to the child's best interests. Parents who do not follow court orders can be held in contempt of court and punished by incarceration or other sanctions. Canada is a country where most children spend more time with their parents than they do with their grandparents. That's because most parents don't live with their children, and when they do live together, only one parent usually gets full custody. The other parent typically receives visitation rights that vary depending on the situation.
