Since California is a community property state, all property acquired by a spouse during the marriage is community property under Family Code 760. This means if you are are married and living in California, any property acquired during marriage is considered half property of each spouse, including income, a house, vehicle, and debts
In a divorce, one spouse is entitled to one-half of the other spouse's income, assets. A spouse is also responsible for half of the debts incurred during marriage.
The division of property and debts in a divorce can be complex and heated. Depending on the financial state of the couple, this process can be extremely involved.

Sometimes having a prenuptial agreement can make the divorce process more manageable, and sometimes it can further complicate matters, such as often is the case with transmutation agreements.
After marriage, spouses can enter into a contract regarding their marital properties and debts. These are called “post-nuptial” agreements, which means after the marriage begins, but before spouses legally separate or divorce.
A type of post-nuptial agreement is known as a “transmutation agreement.” This means spouses agree to change the character of their certain properties. Through a transmutation agreement, the status of community or separate ownership is changed. For example, it can transfer community property to the separate property of one spouse, and more.
Under California Family Code 852, a transmutation must be in writing and signed by the negatively impacted spouse.
Although there are many uncertainties in a divorce, one thing you can count on is that hiring an experienced Los Angeles family law attorney will help you have a more favorable outcome in the end.
To give readers more useful information about a transmutation agreement, our California divorce attorneys are providing a detailed review below.
California: A Community Property State
As stated, when it comes to divorce, California is a community property state. This simply means that if the couple decides to divorce, the property they acquired after their legal marriage is considered to belong equally to both spouses, with the exception of gifts and inheritances.
Community property should be equally divided between the spouses in the divorce. This not only applies to assets but debts as well.
Generally, property owned before the marriage or obtained as a gift or inheritance will belong solely to the spouse who owned it or received it.
Prenuptial Agreements in California
Couples who enter a marriage with multiple or high-value assets may choose to execute a prenuptial agreement. With this agreement, they are allowed to ignore the rules of community property and determine for themselves how they will deal with their debts and assets in the event of a divorce.
However, the prenuptial agreement must be fair to each party. Otherwise, a judge can decide not to honor it.
A prenuptial agreement may dictate that each spouse keeps 100 percent of their own income or specific pieces of property they can keep as their own.
What is a Transmutation Agreement?
Couples are also allowed to make similar agreements after they enter into the marriage but before a divorce.
This is referred to as a post-nuptial agreement. A transmutation agreement is a type of post-nuptial agreement. With a transmutation agreement, the couple mutually agrees to change the character of specific properties and they provide many benefits. For example:
- Changing one spouse's separate property to the other spouse as separate property
- Changing the property from one spouse's separate property to the couple's community property
- Changing property from the couple's community property to one spouse's separate property
Under the California Family Code, transmutation agreements are not valid unless:
- They are in writing
- They are signed by the adversely affected spouse (the one giving up property)
- Both spouses sign them if they are both adversely affected
In addition, the agreement must contain an express declaration. It does not have to use the word transmutation, but it must expressly state that the ownership of the property is changing with the agreement.
If you decide to sign such an agreement, it is wise to have your Los Angeles family law lawyer review it first.
Sometimes transmutation agreements are implied with other transactions. For instance, if one spouse owned a home from a previous marriage and refinanced that home with their new spouse or creates a right of survivorship by transferring the title to include both of their names, a legal transmutation has occurred.
This agreement will be binding in case of divorce and the spouse's property will then be divided according to the agreement.
Transmutation Agreements in Divorce
If the couple should decide to divorce after executing their transmutation agreement, it will be binding in court. Their property will be divided as determined by the agreement and not by California law.
However, either party could challenge the validity of the transmutation agreement on the grounds of one of the following:
- Undue influence
- Duress
- Coercion
If one spouse is successful in challenging the validity of the agreement, it will not be honored by the court. Property and debts will then be settled in accordance with the law.
