Enter the figures below and the split updates as you type. Before you start, gather your original purchase price, down payment, and loan amount, as well as your loan balance at marriage, how much of the community funded the principal payments, and your home's value at marriage.
Down payment and loan amount always add up to the purchase price, so editing one updates the other.
Payments made by the owning spouse alone, and what the home was worth on the wedding day.

The value you are using for division — usually a current appraisal or the sale price.

Determining precise amounts can become much more complicated if additional events have occurred, such as refinancing, additions to the property, title changes, or if commingled funds have been used to pay on the mortgage.
The Moore/Marsden formula is a California method for determining what portion of a home acquired before marriage is marital property and therefore subject to division upon dissolution of marriage.
This methodology evolved from In Re Marriage of Moore (1980) and was later clarified by In Re Marriage of Marsden (1982).
The calculation allows consideration of community contributions, such as reductions in mortgage principal and appreciation in value, while allowing the owner’s separate property interest to remain intact because personal property is often exempt from community property.
Under Family Code Section 2640, principal payments on the loan qualify as community, and improvements that meet certain requirements also qualify; however, interest, taxes, insurance, and maintenance do not create an ownership interest.
The Moore/Marsden method can determine what percent of your home’s value is part of the marital estate if one spouse purchased the residence before the couple married.
This method first identifies payments made from the community that paid down the mortgage — that is, reduced the amount owed on the house. These payments form the basis for calculating the community percentage of ownership of the home. The method will then consider increases in value and the separate owner’s premarital interest.
As with most California community property laws, where possible, the community should receive an asset or liability with approximately equal value at trial time.
It is also helpful to have information about the property’s value, as well as other factors such as the date the parties separated.
Before trial, you will need these six figures. They are the same ones the calculator above asks for.
Four steps take you from the day of purchase to the community’s share of today’s value.
Calculate the original purchase price, down payment, original loan amount, and separate-property principal payments made prior to the marriage.
Calculate how much money was contributed from the community towards reducing the mortgage on the home.
Divide the community contribution — the principal reduction — by the total purchase price at the time of purchase. This provides a pro rata percentage that establishes the community’s interest in the property.
In doing so, you are taking into account all appreciation of the property before the marriage that can be attributed to the separate-property owner. The community’s interest is then split equally between both spouses.
Separate-property analysis determines what remains with the spouse who owned the home before the marriage.
The analysis includes the original down payment, the portion of the loan created by or arising from the spouse’s separate property, all pre-marriage appreciation, and the portion of appreciation created during the marriage attributable to each spouse as separate property.
The community’s percent of the remaining equity is based on how much of the principal has been reduced through payments, while the remainder is considered the owner’s separate property interest. California courts have used these two methods in a complementary manner when considering cases involving Moore and Marsden.
The actual numbers determining how much a wife is entitled to in a California divorce will depend on several factors, including but not limited to the purchase price of the property, loan terms and history, value at the time of sale, and contributions made by both spouses toward their shared ownership.
Mediation gives spouses control over how they will resolve a Moore/Marsden property dispute. The calculation is a guide for the legal process; spouses can use it as a starting point when deciding on a settlement that also considers income taxes, financial circumstances, and potential future needs.
Litigation can increase costs due to the opposing parties’ differing calculations, appraisals, and disputes regarding mortgage documents and the dates used for valuations.
Mediation costs significantly less than litigation while helping each spouse review all necessary documentation and work together, with a mediator’s assistance, to reach a mutually acceptable resolution.
Families First Mediation, led by attorney-mediator Dina Haddad, helps couples identify and review relevant documentation related to their property issue and evaluate options for reaching a settlement.
It calculates a couple’s — the community’s — interest in a property that one spouse bought before the marriage. This calculation is done by accounting for all community principal reductions on the original mortgage and the house’s appreciation while they were together.
No. Mortgage interest is not considered to create a shared ownership interest in an asset between spouses. The Moore/Marsden calculation focuses on the amount of the original mortgage principal reduced by the use of community money.
A refinance does not automatically eliminate the separate-property interest. Its role depends on the new loan, how proceeds were used, and what both parties contributed.
Yes. As long as they comply with applicable state laws governing property rights and provide adequate disclosure, spouses can negotiate alternative property settlements in mediation.
Yes. Adding a spouse to the property’s title may create transmutation issues that could affect how the property is characterized. This depends on your specific situation and the laws that apply to you.
The date of separation helps establish when community contributions cease and the period during which the community acquires assets.
Depending on the degree of difficulty in each case, an attorney, forensic accountant, or similar professional can perform or assist with the calculations.
