Shared custody, or joint parenthood, represents a shift in family law and social norms where both parents maintain legal and physical responsibility for their children after a divorce.

Divorce is frequently analyzed as a factor contributing to family disorganization, as it disrupts established routines, economic stability, and emotional support systems.

The increase in divorce rates in the United States is a multifaceted phenomenon. Legal reforms, such as the introduction of 'no-fault' divorce, have made the process more accessible.

Statistical data on marital trends in the United States historically indicates that a significant majority of divorced individuals eventually enter into new marriages. Research suggests that approximately two-thirds of divorced women remarry, reflecting the enduring cultural importance of marriage as a social institution despite the prevalence of divorce in modern society.
