California Divorce: What is a Moore Marsden Analysis?

Who or What are Moore and Marsden?

Moore and Marsden are two cases decided by the California Supreme Court and the California Appellate Court in 1980 and 1982 respectively. These cases dealt with the issue of how to determine the community property interest in a house.

Generally, a house purchased before marriage will be treated as the purchaser’s separate property. However, during marriage if the mortgage is paid with community funds a portion of the value of the house may become community property. Because California is a community property state, this means all community property is divided equally in a divorce.

When do I Use a Moore Marsden analysis?

The decisions of the Moore and Marsden cases are the basis for what is called the Moore Marsden analysis. The Moore Marsden analysis applies a formula to determine what portion of a house is community property due to mortgage payments made during marriage with community funds.

To apply the Moore Marsden analysis, you need to have two key factors. First, any mortgage payments made must be made with community funds. Second, these payments must include payment of the loan principal and not only interest.

How do I Apply a Moore Marsden Calculation?

If you meet the above two factors, you must compare the market value of your home at the time of your marriage and the market value at them time of your divorce proceedings to calculate the amount the house has increased in value during the marriage.

You then compare the amount principal paid during the marriage to the total purchase price of the house to calculate what percentage of the purchase price was paid during the marriage.

Next you take the percentage of the purchase price that was paid by the community and compare that to the amount your house has increased in value during marriage and add to it the amount of the principal paid by the community to calculate the total amount of the house that the community is entitled to.

Finally, in a divorce this amount is divided between the spouses because it is community property.

For example, if your house was worth $100,000 at the time of marriage and $200.000 at the time of divorce, then the house has increased in value by $100,000.

If you purchased the house for $50.000 and during your marriage paid off $10,000 of principal with community funds, then 20% was paid by the community.

Using the above examples, you take the percentage paid by the community, 20%, of the amount your house increased in value, $100,000, and add the amount of principal paid during the marriage, $10,000, which equals $30,000. This means that the community would be entitled to $30,000 of the $200,000 house.

This would mean that in the above example, each spouse would be entitled to $15,000 as community property is divided equally. The remainder of the house value and the balance due on the loan is kept by the spouse that purchased the house with separate funds before the marriage.

Is There Anything Else I Should be Aware of?

In a typical divorce, there are many additional factors that may be involved in the calculation. Refinancing and home improvements made with community funds both influence the calculation. Further, it may simply be difficult to agree on the required values of the home with your spouse.

Because of the complex nature of the Moore Marsden analysis, it is important to discuss your circumstances with a knowledgeable expert. If you own a home and are considering divorce, please contact one of the experienced attorneys at Lonich Patton Ehrlich Policastri.
