Factors Washington Courts Consider
When determining whether to award alimony and how much, Washington courts evaluate:
The financial resources of the party seeking maintenance, including separate and community property apportioned to that party, and the ability to meet needs independently
The time necessary to acquire sufficient education or training to enable the party seeking maintenance to find appropriate employment
The standard of living established during the marriage
The duration of the marriage or domestic partnership
The age, physical and emotional condition, and financial obligations of the spouse seeking maintenance
The ability of the spouse from whom maintenance is sought to meet their own needs and financial obligations while meeting those of the spouse seeking maintenance
How Long Does Alimony Last?
While there is no universal rule, alimony duration in Washington generally correlates with the length of the marriage:
| Marriage Length | Typical Alimony Duration |
|---|---|
| Under 5 years | 0-2 years |
| 5-10 years | 2-5 years |
| 10-20 years | 5-10 years |
