Vicente Lopez Divorce & Family Law Lawyer, Argentina

A legal principle, followed by most states, under which assets and earnings acquired during marriage are divided equitably (fairly) at divorce. In theory, equitable means equal, but in practice it often means that the higher wage earner gets two-thirds to the lower wage earner's one-third. If a spouse obtains a fault divorce, the 'guilty' spouse may receive less than his equitable share upon divorce.

A lie by one spouse before marriage that provides grounds for an annulment. For example, if a spouse failed to mention that he was still married or was incapable of having children, he has misrepresented himself.

A non-legal term coined by journalists to describe the division of property or alimony-like support given by one member of an unmarried couple to the other after they break up.

The ability of a prospective adoptive parent to provide for the best interests of a child. A court may consider many aspects of the prospective parents' lives in evaluating their fitness to adopt a child, including financial stability, marital stability, career obligations, other children, physical and mental health and criminal history.

Overdue alimony or child support payments. In recent years, state laws have made it difficult to impossible to get rid of arrearages; they can't be discharged in bankruptcy, and courts usually will not retroactively cancel them. A spouse or parent who falls on tough times and is unable to make payments should request a temporary modification of the payments before the arrearages build up.

An arrangement by which parents who do not live together share the upbringing of a child. Joint custody can be joint legal custody (in which both parents have a say in decisions affecting the child) joint physical custody (in which the child spends a significant amount of time with both parents) or, very rarely, both.

A method for defining the ownership of property acquired during marriage, in which all earnings during marriage and all property acquired with those earnings are considered community property and all debts incurred during marriage are community property debts.
