Domesticating Sister-State Judgments in California: The Sister State Money Judgments Act

A creditor with a money judgment from another state — Texas, Nevada, Arizona, Colorado, or anywhere else — who wants to enforce against a debtor in California has two procedural paths: theSister State Money Judgments Act(CCP §§ 1710.10–1710.65) and the older common-law action on a foreign judgment. The Act is the modern, streamlined path; the action is the legacy alternative.

For most out-of-state money judgments, the Act is dramatically faster, simpler, and cheaper than the alternative. Registration converts the sister-state judgment into a California judgment, enforceable through the full California enforcement toolkit (writs of execution, debtor examinations, abstracts of judgment, charging orders, all of it). The process can be completed in 30-60 days under typical circumstances.

This article walks through how California sister-state judgment registration actually works: the eligibility requirements, the procedural mechanics, the grounds for vacating registration, and the strategic considerations for out-of-state creditors deciding whether to use the Act or pursue the common-law action.

What the Act covers

The Sister State Money Judgments Act applies to judgments that meet specific requirements:

• Money judgment.The judgment must require the payment of money. Equitable judgments (specific performance, injunctive relief), declaratory judgments without monetary components, and other non-money judgments are not within the Act’s scope.
• Final judgment.The judgment must be final in the rendering state — not subject to appeal, modification, or further proceedings on the merits. Judgments still subject to appeal can be registered, but the registration is subject to vacatur if the judgment is reversed or modified.
• Sister state of the United States.The Act applies to judgments from other U.S. states. Foreign-country judgments are addressed through different procedures (the Uniform Foreign Country Money Judgments Recognition Act, codified at CCP §§ 1713–1724).
• Within 10 years of entry.The judgment must have been entered within 10 years of the registration date. Older judgments require renewal in the rendering state before registration in California.

Judgments that don’t fit the Act — non-money judgments, judgments older than 10 years, foreign-country judgments — must use the common-law action on a foreign judgment, which involves filing a complaint, serving the debtor, and obtaining a California judgment through ordinary civil procedure.

The registration procedure

The Act’s registration procedure is straightforward but procedurally specific:

Step 1: Apply for entry of judgment

The creditor files an application for entry of judgment with the California Superior Court in the appropriate county. The application is on Judicial Council Form EJ-105 and includes:

• An authenticated copy of the sister-state judgment (typically a certified copy with the rendering court’s authentication)
• A declaration stating the judgment’s current balance, accrued interest, and any post-judgment payments
• The creditor’s address and the debtor’s last-known address
• Information about any prior California enforcement of the same judgment (typically none)

Step 2: Court entry of judgment

Upon application, the court enters a California judgment in the amount of the sister-state judgment plus accrued interest. This is a ministerial act — the court does not at this stage examine the merits of the underlying judgment; that examination happens, if at all, after registration in response to a motion to vacate.

The California judgment is enforceable from the date of entry. Practically, the creditor can immediately apply for writs of execution, record abstracts of judgment, schedule debtor examinations, and use all the other enforcement tools available against any California judgment.

Step 3: Notice to the debtor

After the court enters the California judgment, the creditor serves the debtor with a Notice of Entry of Judgment (Form EJ-110). The notice informs the debtor that:

• The sister-state judgment has been registered as a California judgment
• The debtor has 30 days to file a motion to vacate
• The grounds for vacatur are limited (discussed below)
• The judgment is enforceable in California

The notice and the statutory 30-day window for the motion to vacate are critical procedural features. A registration that fails to provide proper notice can be challenged on procedural grounds even if the underlying judgment is valid.

Step 4: Either immediate enforcement or wait for vacatur motion

In practice, creditors often begin enforcement immediately after registration — the California judgment is enforceable, and waiting for the 30-day vacatur window doesn’t change the underlying procedural posture. The risk: if the debtor files a successful motion to vacate, enforcement actions taken in the meantime may need to be unwound.

For higher-value judgments where the debtor is likely to contest, some creditors wait through the 30-day window before initiating enforcement. For routine judgments where the debtor isn’t expected to contest, immediate enforcement is the standard approach.

Grounds for vacating registration

The Act limits the grounds on which registration can be vacated. The principal grounds:

1. Lack of personal jurisdiction in the rendering court

The most common vacatur ground: the rendering court (Texas, Nevada, etc.) lacked personal jurisdiction over the debtor. This is a constitutional issue — the U.S. Supreme Court’s due-process framework for personal jurisdiction applies to sister-state recognition.

The defendant in the sister-state proceeding can challenge personal jurisdiction in California even if they didn’t challenge it in the original proceeding (provided they didn’t appear and waive the issue). Where the original judgment was entered by default and the debtor lacked sufficient contacts with the rendering state, this is a real defense.

2. Lack of subject-matter jurisdiction

The rendering court’s lack of subject-matter jurisdiction over the dispute is also vacatur grounds. This is rarer because most state courts of general jurisdiction have broad subject-matter jurisdiction, but it can apply where the original case was in a court of limited jurisdiction or where the underlying claim was outside the rendering court’s authority.

3. Fraud in obtaining the judgment

Where the original judgment was procured by fraud — perjured testimony with the plaintiff’s knowledge, fraudulent service of process, deliberate concealment of material facts — the registration can be vacated. The fraud must go to the procurement of the judgment itself; ordinary disputes about the merits aren’t fraud.

4. Lack of full faith and credit eligibility

The U.S. Constitution’s Full Faith and Credit Clause (Article IV, § 1) requires states to give credit to other states’ judgments. Where the original judgment doesn’t meet the constitutional requirements (e.g., from a court without authority to render the judgment), registration can be vacated.

5. Procedural defects in registration

Where the registration itself failed to comply with the Act’s procedural requirements — improper application, defective notice, incorrect court — the registration can be vacated on procedural grounds. The remedy is typically a corrected registration rather than substantive vacatur.

Grounds that aren’t available

Several grounds that defendants sometimes try to raise arenotavailable:

• Disagreement with the merits of the underlying judgment.California cannot relitigate the merits of the original case. The Full Faith and Credit Clause precludes this.
• California public policy disagreements with the underlying claim.The mere fact that California law would have produced a different result on the merits doesn’t support vacatur.
• The debtor’s belief that the case was decided wrongly.Without specific procedural or jurisdictional defects, ordinary disagreement isn’t vacatur grounds.

This narrow set of grounds is the principal advantage of registration over a common-law action: the merits are not relitigated.

When registration fits — and when it doesn’t

Registration is the right path when:

• The judgment is a clean money judgment.No equitable components, no declaratory components, no requirements for ongoing performance.
• The debtor was clearly subject to personal jurisdiction in the rendering state.Where the debtor appeared and litigated, jurisdiction isn’t contestable. Where the debtor was served at their California address for a Texas court action with substantial Texas contacts, jurisdiction is also generally clear.
• The debtor has reachable assets in California.Registration without enforcement is procedural exercise; the value comes from California enforcement.
• Speed matters.Registration produces a California judgment within weeks; the common-law action takes 12-24 months.

Registration may not fit when:

• The judgment includes equitable components.A judgment that requires both money payment and specific performance can’t be cleanly registered — the equitable portion needs separate treatment.
• Personal jurisdiction is contestable.Where the original judgment was a default and the debtor had limited contacts with the rendering state, registration can be vacated. In some cases, the common-law action is preferable because it provides an opportunity to develop fuller jurisdictional facts before California is committed to recognition.
• The original judgment is on appeal.While registration is technically available, the registered judgment is subject to vacatur if the underlying judgment is reversed. Some creditors wait for finality before registering.
• The debtor is judgment-proof.Registration produces a California judgment; if there are no California assets to reach, the registration cost may exceed the recovery.

Action step

Before registering a sister-state judgment, do basic California asset diligence on the debtor. Real-property searches (county recorders), Secretary of State business filings, social-media and public-records searches. The goal is to confirm that the debtor has reachable California assets before incurring registration cost. Where assets are confirmed, the registration cost is small relative to the recovery; where assets are absent, alternative strategies (sister-state asset enforcement, common-law action with discovery rights) may be more efficient.

The common-law action alternative

For judgments that don’t fit the Sister State Money Judgments Act — or for circumstances where the Act’s procedural rhythms don’t fit the case — the common-law action on a foreign judgment remains available. This is essentially a new California civil action seeking judgment based on the prior sister-state judgment.

The common-law action involves:

• Filing a complaint based on the sister-state judgment
• Serving the debtor through ordinary California service procedures
• The debtor’s answer (raising any available affirmative defenses)
• Discovery (limited but available)
• Motion practice and trial (where the case is contested)
• Entry of California judgment

The common-law action is slower and more expensive than registration, but it provides procedural features that registration doesn’t — full discovery rights, jury trial in some circumstances, ordinary California pleading standards. For complex judgments or contested registrations, the common-law action is sometimes the right path.

Strategic considerations for out-of-state creditors

For out-of-state creditors evaluating California enforcement strategy:

Registration first, common-law action as fallback.The standard approach is to attempt registration first. If registration succeeds and isn’t contested, enforcement proceeds. If registration is vacated, the common-law action remains available (subject to limitations and depending on the grounds for vacatur).

Asset diligence before registration.California enforcement procedures are powerful but cost-intensive. Confirming reachable assets before registering avoids wasted registration cost.

Coordination with rendering-state enforcement.Where the debtor has assets in multiple states, coordination of enforcement across states maximizes recovery. California registration can complement (not replace) enforcement in the rendering state and other states.

California counsel advisable for substantial matters.California enforcement procedure has specific local nuances — county-level filing protocols, ePass requirements in some counties, judicial-assignment patterns. For substantial judgments, California-licensed counsel familiar with local practice produces better outcomes than out-of-state counsel handling the matter remotely.

Time the registration relative to debtor activity.Sophisticated debtors may dispose of California assets if they receive notice that California enforcement is coming. Coordinating registration with contemporaneous writs of execution and asset-freezing measures (where available) prevents asset dissipation between registration and enforcement.

Common patterns

A few practical patterns:

The Texas judgment against a California-based business.A Texas creditor with a $500,000 judgment against a California LLC with operating assets in California: registration takes 30-60 days, immediate enforcement against the LLC’s bank accounts and accounts receivable, debtor examination to identify additional assets. Recovery typically substantial within 6-12 months.

The Nevada judgment against a California real-property owner.A Nevada creditor with a $200,000 judgment against an individual who owns California real property: registration, immediate abstract-of-judgment recording in the relevant counties (creating real-property judgment liens), then enforcement-sale procedures or — more commonly — settlement based on the lien’s leverage.

The default judgment with contested jurisdiction.A creditor with a default judgment from a state where the debtor disputes personal jurisdiction: register and prepare for the motion to vacate. The vacatur motion is typically the central event; if jurisdiction is sustained, enforcement proceeds, and if not, the creditor must pursue alternative paths (relitigation in the original state, common-law action with full procedural rights, abandonment of the matter).

When to involve counsel

For routine sister-state registration matters, the procedure is sufficiently formalized that self-represented creditors can sometimes complete it. For substantial matters, contested matters, or matters involving complex enforcement strategy, California counsel involvement is typically warranted.

The cost of California counsel is generally small relative to the recovery on substantial sister-state judgments, and the strategic input — particularly on registration vs. common-law action choice, asset diligence, and enforcement coordination — produces better outcomes than the standard form-driven approach.
