Yes. A final judgment settles the case, but California courts can modify custody, visitation, child support, and in many cases spousal support when circumstances change. You ask by filing Form FL-300, the Request for Order, in your existing case. The court keeps the same case number, and your request is heard by the family court that made the original orders.
Form FL-300, the Request for Order, filed in your existing case, together with a current Form FL-150, Income and Expense Declaration, so the court can see both parents' current financial situation. Child support can generally be modified when income, custody time, or the child's needs have changed since the last order.
You respond with Form FL-320, the Responsive Declaration to Request for Order, and serve it before the deadline set by the hearing date. Your response tells the court which requests you agree with, which you disagree with, and what you are asking for instead, supported by your own declaration of the facts.
Yes. If your original orders were made in a parentage case rather than a divorce, post judgment modification works the same way: FL-300 to request a change, FL-320 to respond to one. Virdix asks what kind of case your original order came from and uses the right caption and forms for it.
No. You have the right to represent yourself in California family court, and many parents handle post judgment changes on their own. Virdix is not a law firm and does not give legal advice; if your case involves complex finances or safety concerns, consulting an attorney is a good idea.
