There are two types of support, temporary and permanent. Like child support, temporary spousal support is based on a pure mathematical calculation. The courts consider the respective incomes and filing status and the program will calculate support.
Permanent spousal support is based on what attorney's and judges call the 4320 factors. These factors include age, health, educations, standard of living etc. of the supported spouse. In other words, this is more of a subjective approach. Once the court considers these factors, the court will determine how much the supported spouse should receive.
Where marriages are ten years or longer, the supported spouse will receive spousal support for the rest of their life until they remarry, death, ,or further order of the court. Marriages that are less the ten years, the supported spouse will only receive spousal support for one half the length of the marriage. For example, if the parties were married for eight years, the supported spouse will receive support for four years.
