A Moore-Marsden analysis is a legal method used in California family law to determine the [[Community Property|community property]] interest in a [[Separate Property|separate property]] asset when community funds or efforts have been used to enhance the value of that asset. This analysis is typically applied during [[Divorce|divorce]] proceedings to ascertain the extent to which community contributions have increased the value of a [[Spouse|spouse's]] separate property. The analysis involves calculating the community's [[Interest|interest]] in the separate property by considering the contributions made by the community, such as mortgage payments or [[Improvements|improvements]], and the resulting increase in the property's value. The analysis is named after two California cases: [[Marriage of Moore]] and [[Marriage of Marsden]], which established the framework for this calculation.
