After the divorce

Changing custody, support and other orders after a California divorce

Evenpart · · 4 min read

After a California divorce, orders about child custody, visitation, child support and spousal support can generally be changed if circumstances change. You usually ask by filing a Request for Order (form FL-300) in the same case and serving the other party. Support changes generally reach back only to the date you filed, so delay can cost money. Property division is different: it is usually final, and setting aside a judgment is possible only on limited grounds and within strict time limits under Family Code sections 2120 and following.

What can usually be changed

The court generally keeps power to change custody, visitation and child support orders until the children are adults, and spousal support while support is still owed or the court has kept jurisdiction over it. If the parties agreed in writing that spousal support cannot be changed, that agreement may limit changes, so read the judgment carefully.

A change usually requires a meaningful change in circumstances since the last order. Common examples include a significant change in income, job loss, a new work schedule, a change in how much time each parent actually spends with the children, a move, health problems or the needs of a growing child.

How to ask the court

Parents and former spouses who agree on a change can write a stipulation and submit it to the judge for approval. Informal agreements that are never approved are not court orders and can cause problems later, especially with support.

If you do not agree, the usual tool is a Request for Order (form FL-300). The steps generally look like this.

  • Fill out the FL-300 explaining what order you want and why, attaching declarations as needed.
  • For support changes, include a current Income and Expense Declaration (form FL-150) with proof of income.
  • File the papers with the court, get a hearing date, and have the other party served by someone other than you within the required time.
  • For custody or visitation disputes, attend court child custody mediation or recommending counseling if ordered.
  • Attend the hearing; the judge may decide or ask for more information.

Why timing matters for support

A judge generally can change child support or spousal support only back to the date the request to change it was filed, not to the date your circumstances changed. Support that already came due before then is generally not reduced. If your income drops or rises significantly, filing promptly protects you. If a local child support agency is involved in your case, it can also help request a change in child support.

Property division and setting aside a judgment

Unlike support and custody, the division of property and debts is generally final once the judgment is entered. If an asset was never divided in the judgment, the court can generally divide it later on request. Otherwise, reopening the property division usually requires a motion to set aside the judgment.

Family Code sections 2120 to 2129 allow a set-aside only on specific grounds, such as actual fraud, perjury in the financial disclosures, duress, mental incapacity, certain mistakes, or failure to comply with the disclosure requirements. Each ground has its own deadline, generally either one year after discovering the problem or one or two years after entry of judgment, depending on the ground. A judgment cannot be set aside just because it later seems unfair. Other procedures with shorter deadlines may also apply. Because the deadlines are strict, talk to an attorney as soon as you suspect a problem.

Your next steps

  • Read your judgment to see which orders can be changed and whether any spousal support terms are non-modifiable.
  • If circumstances change, file a Request for Order promptly, especially for support.
  • Write down and document the specific changes since the last order before you file.
  • If you believe a property judgment was based on fraud or incomplete disclosure, consult an independent family-law attorney licensed in California quickly because deadlines are strict.
