California Penal Code Section 713 sets a strict evidentiary rule for undertaking breach actions. When a person is required to give an undertaking to keep the peace or be of good behavior, a certified record of conviction for the offending conduct will serve as conclusive evidence of breach in the ensuing action. Understanding how California Penal Code Section 713 works, how it fits within related procedures, and where defenses remain is critical for anyone facing allegations that they violated an undertaking.

What California Penal Code Section 713 Says

Section 713 appears in a short sequence of statutes governing security to keep the peace proceedings. In these matters, a court may require an undertaking after a showing that there is just reason to fear a threatened offense. If the person later commits the proscribed conduct and is convicted, Section 713 provides that the offense stated in the record of conviction must be alleged as the breach, and that record is conclusive evidence of the breach.

This framework sharply narrows the dispute in an undertaking breach action. The focus is not on relitigating the underlying crime but on whether the conviction record matches the conduct prohibited by the undertaking. For background on evidentiary burdens generally, see our guide on burden of proof standards in California.

What counts as an undertaking under Section 713

In this context, an undertaking is a formal promise to keep the peace or maintain good behavior, backed by a bond the court may order after a hearing. Typical features include a defined period and specific conduct to avoid. While other court orders and conditions exist in California practice, Section 713 specifically governs undertakings issued within the Security to Keep the Peace chapter.

• Peace or good behavior undertakings: Ordered after a magistrate hearing when there is just reason to fear a threatened offense, and typically limited in duration.
• Not the same as probation or bail: Probation terms and pretrial release conditions are governed by other statutes and standards. The concepts are related, but Section 713's conclusive-evidence rule applies to the particular undertaking breach action described in this chapter.

The evidentiary punch: conclusive evidence

Conclusive evidence means the certified record of conviction cannot be contradicted in the undertaking breach action. If the record shows a conviction for conduct that the undertaking prohibited, the breach element is established without further proof. The dispute then shifts to issues such as the scope of the undertaking, timing, and remedies, rather than whether the person committed the offense.

California law also recognizes that certified conviction records are admissible to prove the commission of an offense in various contexts. That broader principle aligns with Section 713's specific rule and is reflected in state evidence law. Still, Section 713's conclusive effect is unique to undertaking breach actions and operates more forcefully than ordinary evidentiary admissions.

Elements and definitions under California Penal Code Section 713

To prevail in an action to prosecute the undertaking, the People typically must show:

• A valid undertaking was issued after the required hearing.
• A qualifying conviction exists for the offense the undertaking forbids.
• Pleading linkage: The offense described in the conviction record is specifically alleged as the breach of the undertaking.

When these align, the conviction record serves as conclusive evidence of the breach for purposes of the undertaking action. The standard of proof for the underlying crime was met in the criminal case; the breach action does not reopen that question.

Procedure and timeline in Section 713 matters

• Initial information and hearing: A magistrate receives sworn information alleging a threatened offense and holds a hearing to decide whether there is just reason to fear it.
• Issuing the undertaking: If warranted, the court orders an undertaking to keep the peace or be of good behavior for a defined period.
• Conviction for the proscribed conduct: A later conviction establishes that the undertaking has been broken.
• Action on the undertaking: The prosecutor presents the conviction record to the court, which directs that the undertaking be prosecuted in an action brought in the name of the People.
• Conclusive proof of breach: In that action, the certified conviction record conclusively proves breach when it matches the undertaking's terms.

Because the record of conviction drives the outcome, early assessment and planning are essential. Where companion criminal matters or appeals are pending, counsel should consider how developments there may affect the undertaking action's timing and posture.

Defense strategies in Section 713 cases

Even with Section 713's conclusive-evidence rule, targeted defenses remain:

• Challenge the linkage: Scrutinize whether the offense in the conviction record is the one the undertaking actually forbade. If the undertaking prohibited violent conduct and the conviction was for a nonviolent regulatory offense, the conclusive-evidence rule may not apply because the necessary match is missing.
• Scope and clarity of the undertaking: Vague or overbroad terms can raise enforceability concerns. Ambiguities may be construed narrowly, particularly where liberty interests are implicated.
• Timing and jurisdiction: Confirm the convicted conduct occurred while the undertaking was in force and within the appropriate jurisdiction.
• Underlying conviction posture: Although the breach action does not relitigate the crime, the validity and status of the conviction matter. If a conviction is vacated, reversed, or set aside, its use as conclusive evidence may be undermined.

Constitutional considerations and collateral issues

Due process. Because Section 713 limits factual contest over breach, counsel should assess whether the particular application of the statute preserves fair notice, an opportunity to be heard, and a clear path to challenge the underlying conviction through the correct channels.

Double jeopardy. The undertaking action enforces a bond obligation arising from a peace or good behavior order. Whether additional consequences are punitive for double jeopardy purposes depends on the context. Careful analysis is warranted alongside our overview of California double jeopardy protections.

Related proceedings. Probation violations, parole issues, and pretrial conditions are governed by different statutes and standards. Understanding the difference between parole and probation helps situate the undertaking action within the broader system and anticipate collateral effects.

Evidence, records, and certified copies

Certified court records are central to Section 713 actions. A properly certified record of conviction will be the key exhibit. Counsel should verify certification, completeness, and that the record accurately describes the offense alleged as the breach. In parallel criminal or administrative settings, certified conviction records also play an important role, consistent with California evidence law.

Practical guidance for defendants and families

• Act quickly. Undertaking actions can move fast once a conviction record is available. Deadlines to respond or raise procedural objections come up early.
• Coordinate with appeals and post-conviction work. If you are pursuing relief from the underlying conviction, ensure your legal team connects that strategy to the undertaking case. Explore expungement and post conviction relief options where appropriate.
• Gather documents now. Obtain the written undertaking, hearing transcripts, certified conviction record, and any orders that define the conduct at issue.
• Mitigation matters. Even when breach is established, rehabilitation steps, compliance with other terms, and community support can influence outcomes tied to the undertaking.

Frequently asked questions

• Can I contest the facts of the conviction in the undertaking action? No. Section 713 treats the certified conviction record as conclusive on breach, so factual relitigation happens in the criminal appeal or post-conviction forum, not in the undertaking action.
• Does Section 713 apply to probation violations? No. Probation violations are governed by their own statutes and standards. Section 713 addresses breach of a peace or good behavior undertaking issued under the Security to Keep the Peace chapter.
• What if the undertaking terms were unclear? Ambiguity in the undertaking may be a viable defense. The prosecution must allege a breach that matches the offense stated in the conviction record and the undertaking's lawful terms.
