Divorce (or the dissolution of marriage) is the termination of a marital union, the canceling and/or reorganizing of the legal duties and responsibilities of marriage, thus dissolving the bonds of matrimony between a married couple under the rule of law of the particular country and/or state.Divorce should not be confused with annulment, which declares the marriage null and void; with legal separation (a legal process by which a married couple may formalize a de facto separation while remaining legally married) or with de facto separation (a process where the spouses informally stop cohabiting).Divorce laws vary considerably around the world, but in most countries it requires the sanction of a court or other authority in a legal process. The legal process of divorce may also involve issues of alimony (spousal support), child custody, child visitation / access, parenting time, child support, distribution of property, and division of debt. In most countries monogamy is required by law, so divorce allows each former partner to marry another; where polygyny is legal but polyandry is not, divorce allows the woman to marry a new husband.Divorce can be a stressful experience: affecting finances, living arrangements, household jobs, schedules, parenting and the outcomes of children of the marriage as they face each stage of development from childhood to adulthood. If the family includes children, they may be deeply affected.The only countries that do not allow divorce are the Philippines and the Vatican City, an ecclesiastical state, which has no procedure for divorce. Countries that have relatively recently legalized divorce are Italy (1970), Portugal (1975), Brazil (1977), Spain (1981), Argentina (1987), Paraguay (1991), Colombia (1991* ) Ireland (1996), Chile (2004) and Malta (2011).
