California Divorce: What is a Moore/Marsden Calculation?

Finances are often among the most challenging issues during a divorce, especially when dividing assets and property acquired during the marriage. The Moore/Marsden calculation is a more complex aspect of this process.

California is a community property state, meaning that when couples acquire property during their marriage, those assets are split 50/50 in the case of a divorce. In contrast, assets owned by one spouse before the marriage are considered that spouse’s separate property. But what happens when one spouse owns real estate when they enter the marriage, but marital funds are used to pay the mortgage or improve the property?

That’s where the Moore/Marsden calculation comes in. It can significantly affect property division and the final settlement in a divorce case. This article will discuss this calculation, how it works, and its potential impact on divorce proceedings.

What is the Moore/Marsden Calculation?

The Moore/Marsden calculation arises from two pivotal California appellate court cases: Marriage of Moore (1980) and Marriage of Marsden (1982). These cases established a formula to determine the community property interest in a property that was initially the separate property of one spouse. Still, the property was paid down or improved with community funds during the marriage.

In simpler terms, if one spouse owned a home before getting married and the mortgage on that home was paid down using the couple’s joint income after they got married, the community (both spouses) may be entitled to a portion of the increased equity in the home. The Moore/Marsden calculation helps to determine what portion of the property’s equity is considered community property versus the separate property of the original owner.

How Does the Moore Marsden Calculation Work?

The Moore Marsden calculation takes the following factors into account. These factors help establish a clear line between community property (belonging to both spouses) and what should remain separate property (belonging to the purchasing spouse).

  • Original Purchase Price of the Property — It starts with the amount the spouse who purchased the property paid for it. 
  • Determine the Initial Equity — Calculate the equity in the property at the time of marriage by subtracting the mortgage balance from the property’s fair market value.
  • Calculate the Paydown of Principal — Determine the amount of principal paid on the mortgage with community funds during the marriage. Interest payments and other expenses are generally not included in this calculation. Only the principal reduction counts.
  • Appreciation of the Property — Assess the property’s fair market value during separation or trial.
  • Community Interest in Appreciation — The community is entitled to a share of the property’s appreciation during the marriage in proportion to the principal amount paid with community funds.

The formula generally looks like this:

Community Property Interest = (Principal Paid with Community Funds/Original Purchase Price)×Total Appreciation during Marriage

This formula calculates the community’s share of the appreciation. To find the total community property interest, you add the principal paid with community funds to the community’s share of the appreciation.

Example of the Moore/Marsden Calculation

Here’s an example of how the Moore/Marsden calculation would work.

  • Original Purchase Price — $200,000
  • Mortgage Balance at Marriage — $150,000
  • Mortgage Balance at Separation — $100,000
  • Fair Market Value at Marriage — $220,000
  • Fair Market Value at Separation — $300,000
  • Principal Paid with Community Funds — $50,000

Step 1 — Initial Equity at Marriage = $220,000 (Fair Market Value) – $150,000 (Mortgage Balance) = $70,000.

Step 2 — Principal Paid with Community Funds = $50,000.

Step 3—Appreciation During Marriage = $300,000 (Fair Market Value at Separation)—$220,000 (Fair Market Value at Marriage) = $80,000.

Step 4 — Community Interest in Appreciation = ($50,000 / $200,000) * $80,000 = 0.25 * $80,000 = $20,000.

Total Community Property Interest = Principal Paid with Community Funds ($50,000) + Community Interest in Appreciation ($20,000) = $70,000.

So, in this example, the community interest in this property is $70,000, which would then be subject to division between the spouses during the divorce.

Impact on Divorce Cases

The Moore/Marsden calculation can significantly impact property division in a divorce. Understanding and accurately applying this calculation is crucial for several reasons:

  • Equitable Distribution — It ensures a fair division of property by recognizing the contributions of both spouses to the acquisition and appreciation of the property, even if one spouse originally owned the property before marriage.
  • Financial Settlements — Accurate calculation can affect the overall financial settlement, influencing decisions regarding alimony, child support, and the division of other marital assets.
  • Negotiations — Knowing the community property interest can leverage negotiations, potentially leading to more favorable settlements for one or both parties.
  • Legal Strategy — Divorce attorneys use the Moore/Marsden calculation to develop their legal strategies, advising clients on whether to settle or proceed to trial based on the potential division of assets.
