About Moore/Marsden and Our Advanced Calculator
The Moore/Marsden Doctrine
The Moore/Marsden doctrine stems from California case law and governs how equity in a home is divided when separate property funds were used to acquire or improve a property, and community funds contributed to mortgage payments during the marriage.
It ensures a fair allocation of appreciation and principal paydown between separate and community interests in divorce proceedings.

Legal Background
The Moore/Marsden calculation is based on two landmark California court cases:
In re Marriage of Moore (1980)
Established the principle that when separate property is used as a down payment on a home, but community funds are used to pay the mortgage, both separate and community property interests must be recognized.
In re Marriage of Marsden (1982)
Further clarified how to calculate the separate and community property interests in a home, particularly focusing on the allocation of appreciation in value.
Together, these cases form the basis of what is now known as the Moore/Marsden rule, a vital calculation in California family law that the CaseMate MMA Calculator automates and enhances.
