The length of time spousal support is paid depends on the laws of each state and other variables, according to WomansDivorce.com. These variables include how long the marriage lasted, the ability to pay and the needs of the spouse. Others factors considered are children, health and the spouse's work skills.
Spousal support is usually terminated if the receiving spouse gets remarried, explains WomansDivorce.com. Generally, spousal support lasts approximately one-third the length of years of the marriage but other considerations are used to determine the final decision. Each state has its own rules, and most decisions are made on a case-by-case basis.
