Alimony, spousal support, spousal maintenance, or domestic partner support (collectively, spousal support) is generally financial support in the form of periodic payments (usually monthly) paid by one spouse or domestic partner to the other spouse or domestic partner upon divorce.

The person paying spousal support or the person receiving spousal support may seek to modify the court’s order for support—usually by increasing it or decreasing it—due to a material change in circumstances of the person paying support or the person receiving support.

Spousal support laws vary from state to state and are generally located in a state’s statutes—often in the family or domestic code.

In Wyoming, alimony, also known as spousal support, is not a mandatory provision in divorce proceedings but may be awarded based on a variety of factors. The state's statutes allow for either party to request alimony, and the court considers several factors when determining whether to award spousal support. These factors include the duration of the marriage, the standard of living established during the marriage, the age and health of the spouses, their earning capacities, and the financial resources of each party. Wyoming law permits modification of an existing alimony order if there has been a material change in circumstances. This change must be significant and not anticipated at the time of the original decree. Either the payor or the recipient can request the court to increase, decrease, or terminate the spousal support based on these changed circumstances. The process involves filing a petition with the court that issued the original order and demonstrating the material change in circumstances that justifies the modification.
