If you are going through or have gone through a divorce in California you’ve probably figured out that the length of marriage becomes very important and can become a hotly contested issue at divorce time. While the length of marriage is relevant for a number of issues in divorce litigation, there is special and controversial significance in relation to spousal support. This is because, under the family code, the future of spousal support may follow a very different course once a marriage hits the 10-year mark, as opposed to a marriage that lasted less than 10 years. This particular magic number comes into play because under the family code, a marriage of 10 years or more is presumed to be a marriage of “long duration” (more commonly referred to as a long-term marriage).
