A Prenuptial Agreement (often referred to as a “prenup”) is an agreement entered into by a couple before they get married setting out how they will organise their finances during the marriage and what they would wish to happen in relation to financial matters in the unhappy event of a divorce.

Prenuptial agreements should be legally binding in divorce settlements, but only after the needs of the separating couple and any children have been taken into account, the Law Commission has recommended. (The Guardian)

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. (Wikipedia)

The original concept of a common-law marriage is a marriage that is considered valid by both partners, but has not been formally registered with a state or church registry, or a formal religious service. In effect, the act of the couple representing themselves to others as being married acts as the evidence that they are married. (Wikipedia)
