 It is not uncommon for a parent with sole physical custody to share legal custody with the other parent, but it is uncommon for parents to share physical custody while one parent has sole legal custody.Historically, sole custody was the most common form of child custody granted after divorce.Since the 1980s, joint physical custody with shared parenting have become much more common, and in some jurisdictions there is a legislative preference or presumption in favor of joint legal custody, joint physical custody or both.
