SIS vs. SES in Missouri: What Each Means for Your Future

Posted by Beal & Whitener | Nov 01, 2026

If you are facing criminal charges in Missouri, hearing that you might receive probation can bring relief. You may be able to keep working, support your family, and remain in your community. But before accepting a plea agreement, you need to understand what kind of probation is being proposed.

Two common Missouri dispositions are a suspended imposition of sentence (SIS) and a suspended execution of sentence (SES). Although their names sound similar, they can have very different consequences for your criminal record and your exposure if probation goes wrong.

Understanding that difference can help you make an informed decision about your case.

What Is a Suspended Imposition of Sentence in Missouri?

With an SIS, you plead guilty or are found guilty, but the judge does not impose a sentence. The court commonly places you on probation and requires you to satisfy specific conditions.

Missouri law expressly distinguishes suspending the imposition of sentence from imposing a sentence and suspending its execution. The difference is whether a sentence has actually been pronounced. Section 557.011, RSMo.

For example, a judge might grant an SIS and place you on two years of probation. Those two years describe the probation period; they do not mean you have received a two-year jail sentence.

An SIS generally allows you to avoid a judgment of conviction under Missouri law if you successfully complete probation without the court later imposing sentence. However, an SIS follows a guilty plea or finding of guilt. It is not an acquittal, and it does not mean the charge never existed. Missouri's Kansas City Municipal Court explanation of probation describes these basic distinctions.

What Is a Suspended Execution of Sentence?

With an SES, the judge imposes a sentence but suspends carrying it out while you serve probation.

For example, the court might impose a four-year prison sentence, suspend its execution, and place you on five years of probation. The four-year sentence and five-year probation term serve different purposes.

An SES is a conviction. Successfully completing probation does not automatically remove that conviction or close the record. The benefit is the opportunity to complete probation without serving the suspended sentence. Missouri State Highway Patrol, Criminal History Background Checks.

When reviewing an offer, ask your attorney to identify both the sentence, if any, and the probation term. “You are getting probation” does not tell you everything you need to know.

Will an SIS Show Up on a Background Check?

An SIS does not immediately make your case private. Records generally remain open during probation.

When the case is finally terminated following successful SIS probation, Missouri law generally provides for closure of the official case records, subject to statutory exceptions. Section 610.105 also preserves access to the court's judgment or order or the prosecutor's final action. You should not assume that every trace of the proceeding becomes inaccessible. Section 610.105, RSMo.

Closed records also continue to exist. Missouri law allows specified agencies and authorized entities to access them for particular purposes, including criminal justice functions, certain employment screening, and driver's license administration. Record closure is different from expungement. Section 610.120, RSMo.

Before answering an application, review its exact wording with counsel. A question about convictions differs from one asking whether you have ever pleaded guilty or received probation.

What Happens If You Violate SIS or SES Probation?

The distinction becomes especially important if the court revokes probation.

With an SIS, no sentence has yet been imposed. Upon revocation, the judge may impose a sentence available under Missouri law for the underlying offense. The probation period does not establish a ceiling on that punishment.

With an SES, a sentence already exists. Upon revocation, the court may order that previously imposed sentence executed.

A reported violation does not automatically require revocation. Depending on the circumstances and applicable law, the court may continue probation, modify conditions, or use another authorized response. Section 559.036, RSMo.

If you miss an appointment, receive a violation notice, or face a new charge, contact your attorney promptly. Gather records explaining what happened, including proof of treatment, attendance, payments, or a medical emergency.

Does Probation Mean There Will Be No Jail Time?

You should review every condition before assuming probation means no confinement.

Missouri law permits detention as a condition of probation in qualifying cases. An SIS or SES therefore does not, by itself, guarantee that the entire disposition will involve no time in custody. Section 559.026, RSMo.

Other conditions may include restitution, community service, and treatment. Missouri law requires that a person placed on probation receive a certificate explicitly stating the conditions of release. Read that document carefully and ask questions before leaving court. Section 559.021, RSMo.

If work, transportation, health, or caregiving responsibilities could interfere with compliance, discuss those problems early so your attorney can address them.

Is an SIS Always the Better Outcome?

Avoiding a Missouri conviction can make an SIS valuable, but evaluating an offer requires more than comparing labels.

The court considers the offense's circumstances and your history and character when deciding whether probation is appropriate. An SIS is not something every defendant is automatically entitled to receive. Section 559.012, RSMo.

You also need advice about consequences outside the immediate criminal case. For example, federal immigration law can treat a guilty plea followed by probation as a conviction even when state law withholds a judgment of conviction. Anyone who is not a U.S. citizen should obtain advice about immigration consequences before entering a plea. U.S. Department of Justice, immigration conviction standards.

Before accepting an agreement, ask:

  • Is the proposed disposition an SIS or SES?
  • What sentence could I face if probation is revoked?
  • What conditions must I complete, and by when?
  • How will this affect my record and required disclosures?
  • What defenses or alternatives should we evaluate first?
