Spousal maintenance is a form of financial support.
It’s sometimes known as spousal support. In marriage, it’s paid by one spouse to another when the second spouse can’t fully support themselves.
Spousal maintenance can also apply to de facto relationships, but there are special requirements. You must have lived together for at least two years, or have a child (or children) together. Spousal maintenance payments can be regular and ongoing or paid annually as a lump sum.
