California Custody Fraud

The Problem in California

California's family courts handle over 150,000 custody cases annually. While California has stronger due process protections than some states, service of process fraud still occurs. Parents lose custody through default judgments when they're never properly notified of proceedings.

Under California Code of Civil Procedure, service by publication is supposed to be a last resort. But in practice, some attorneys abuse this process, using outdated addresses or inadequate search efforts to claim they couldn't locate the respondent.

California Service of Process Requirements

California law requires personal service for family law cases. Service by publication is only permitted when the court finds that the respondent cannot with reasonable diligence be served in any other manner. However, what constitutes "reasonable diligence" is often loosely interpreted.

The good news: California allows motions to set aside default judgments based on improper service, and courts generally favor deciding cases on their merits. But the burden is on the parent who was defrauded to prove the service was improper.

Service of Process Laws in California

California law establishes a hierarchy of service methods for family law cases. Under California Code of Civil Procedure (CCP) section 415.10, personal service — physically handing the documents to the respondent — is the preferred method. If personal service cannot be accomplished after reasonable diligence, CCP section 415.20 allows substitute service, where papers are left with a competent member of the household who is at least 18 years old, and a copy is mailed to the respondent's dwelling.

Service by publication, governed by CCP section 415.50, is considered a last resort. The petitioner must file a declaration demonstrating that the respondent "cannot with reasonable diligence be served in another manner specified in this article." The court must issue an order authorizing publication before it can proceed. Publication must then appear in a newspaper of general circulation in the area where the respondent is most likely to receive notice, once per week for four successive weeks. Despite these safeguards, petitioners sometimes submit inadequate declarations of diligence — for example, checking a single outdated address or running a minimal online search — and courts may approve publication without scrutinizing these declarations closely enough.

California also permits service by posting under CCP section 415.45 in limited circumstances, and electronic service under CCP section 1010.6 when the parties have agreed to accept electronic service. However, these alternative methods generally require the court's prior approval in family law matters.

California Rule of Court 5.68: Service in Family Law Cases

California Rule of Court 5.68 specifically governs the manner of service of summons and petition in family law proceedings. Under Rule 5.68(a), the petitioner must arrange service by one of the following methods:

1. Personal service (CCP § 415.10)
2. Substituted service (CCP § 415.20)
3. Service by mail with notice and acknowledgment of receipt (CCP § 415.30)
4. Service on person outside of the state (CCP § 415.40)
5. Service on a person outside the United States, which must comply with the Hague Convention on Service Abroad or the Inter-American Convention on Letters Rogatory
6. Service by posting or publication (CCP §§ 415.50 and 413.30)

Under Rule 5.68(b), a response to a family law petition may be served by any of the methods above and may also be served by mail without notice and acknowledgment of receipt. Under Rule 5.68(c), the court has jurisdiction over the parties and control of all subsequent proceedings from the time of service. A general appearance by the respondent is equivalent to personal service. Rule 5.68 was most recently amended effective January 1, 2026.

How to Challenge a Default Custody Judgment in California

Remedy: Motion to Vacate under CCP § 473

Governing law: CCP § 473(b), CCP § 473(d), CCP § 473.5, Family Code §§ 2120-2129

CCP § 473(b) is the primary vehicle. A party may move to vacate a default judgment taken through "mistake, inadvertence, surprise, or excusable neglect" — filed within 6 months of the judgment. If the motion is accompanied by an attorney's affidavit of fault, relief is mandatory. For fraud (such as a false address certification), the clock runs from discovery of the fraud, not from entry of judgment.

Void judgment — no time limit: CCP § 473(d) allows setting aside a void judgment at any time. A judgment obtained through fraudulent service may be void for lack of jurisdiction over the person, making this provision critical in cases involving false address certifications.

Read that the way you would read it in Texas. Whether the judgment is void is the contested question, not the deadline. Where the record looks regular on its face — a return of service reciting valid service — proving otherwise takes evidence from outside the record, and that route usually does have a deadline. Treat the no-time-limit rule as a fallback argument, not a schedule.

CCP § 473.5 provides a separate remedy for cases where service did not result in actual notice. A motion may be filed within a "reasonable time" but no later than two years after entry of judgment. The moving party must submit an affidavit stating that lack of actual notice was not caused by avoidance of service or inexcusable neglect.

For family law cases specifically, Family Code § 2122 provides additional grounds including actual fraud, perjury, duress, and mistake. Motions based on fraud or perjury must be brought within one year of discovery. Under Family Code § 2121, the court retains jurisdiction to set aside a judgment at any time if obtained through extrinsic fraud.

Key difference from Texas: California's 6-month window under § 473(b) is stricter than Texas's 4-year Bill of Review window. However, a void judgment can be attacked at any time under § 473(d), with no time limit — similar to Texas's void judgment doctrine, and carrying the same caveat: whether the judgment is void is the contested question, not the deadline. How to read that.
