When a couple gets married, they have two choices.
They can either enter into the marriage subject to the state laws that govern it, however those laws may change in the future, or they can enter into the marriage with a premarital agreement and choose their own rules to govern their relationship.
Many couples choose to customize their circumstances rather than leave their futures in the hands of state law. Think of a premarital agreement as a planning tool, not a weapon.
Premarital agreements can protect assets like inheritance, real estate, and businesses. They can also include provisions about intellectual property, financial accounts, stocks, and earnings during marriage. Spousal support, often known as alimony, is commonly addressed as well. Provisions about child custody or child support are not included in California premarital agreements.
Sometimes, couples choose to isolate particular assets as separate property. Or, a couple may choose to change the default marital regime entirely, for example by agreeing to a no-community property agreement. The content of a prenuptial agreement is customizable and can vary widely to meet the needs of the couple.
