Historically, if contributions were roughly equal, then there was a tendency to start from a 50/50 basis and to adjust this to allow more to a spouse who would be out of the workforce due to childcare responsibilities, or whose earning power was much less, resulting in distributions such as 60/40 or 55/45. However, where child support is to be paid, this approach may no longer be applicable as the child support may itself adjust for the extra expense of caring for children.
