Compare · Indecent Assault vs. Sexual Assault
One statute covers indecent contact. The other covers intercourse. The gap between them is one of the most consequential in this area of the law.
Indecent assault under § 3126 and sexual assault under § 3124.1 are frequently charged together because they can arise from the same event, but they are not interchangeable, and the difference between them affects far more than the sentence a court can impose. Indecent assault covers indecent contact, as opposed to intercourse or deviate sexual intercourse as those terms are defined in § 3101, and it's graded anywhere from a misdemeanor of the second degree up to a felony of the third degree depending on the circumstances. Sexual assault under § 3124.1 requires intercourse or deviate sexual intercourse without consent and is graded as a felony of the second degree. Neither statute requires the Commonwealth to prove forcible compulsion — that element belongs to the more serious offenses of rape and involuntary deviate sexual intercourse under §§ 3121 and 3123. Because a reduction from § 3124.1 to § 3126 changes not just the sentence but the registration tier, the realistic availability of diversion, and how the rest of a person's life is affected, this distinction deserves as much attention as any other part of the case.
The short answer
Indecent assault (18 Pa.C.S. § 3126)
Indecent assault covers indecent contact with another person, or causing another person to have indecent contact, without consent — it does not require intercourse or deviate sexual intercourse. Grading ranges from a misdemeanor of the second degree up to a felony of the third degree depending on factors like the complainant's age, whether the person has a prior conviction under this section, or whether the complainant was unconscious or otherwise unable to consent. Aggravated indecent assault under § 3125 sits between this offense and sexual assault, covering penetration without intercourse. Registration exposure and eligibility for ARD or another diversion program vary significantly depending on where in that grading range a particular case falls.
Sexual assault (18 Pa.C.S. § 3124.1)
Sexual assault requires proof of intercourse or deviate sexual intercourse, as those terms are defined in § 3101, without the complainant's consent — it does not require forcible compulsion, which is what separates it from rape under § 3121 and involuntary deviate sexual intercourse under § 3123. It's graded as a felony of the second degree, carrying a statutory maximum under § 1103, and it generally carries greater registration exposure than indecent assault. Because the conduct element is intercourse rather than indecent contact, cases charged here are typically evaluated for SOAB or SVP assessment more routinely, and ARD is rarely realistic once a case is charged at this level.
| What matters | Indecent assault (18 Pa.C.S. § 3126) | Sexual assault (18 Pa.C.S. § 3124.1) |
|---|---|---|
| Governing statute | § 3126 | § 3124.1 |
| Conduct required | Indecent contact, not intercourse | Intercourse or deviate sexual intercourse as defined in § 3101 |
| Grading range | Misdemeanor of the second degree up to felony of the third degree | Felony of the second degree |
| Statutory maximum | Up to 1–7 years depending on grade, under §§ 1103/1104 | Up to 10 years under § 1103 |
| Forcible compulsion required? | No — that element belongs to § 3121 | No — that element belongs to § 3123 |
| Registration tier exposure | Depends on grade, generally Tier I or II under § 9799.14 | Generally higher tier exposure under § 9799.14 |
| SOAB/SVP assessment likelihood | Possible, more common at higher grades | More routine given the felony-second grading |
| ARD or diversion realism | Sometimes available depending on grade and county | Rarely realistic once charged at this level |
| Middle-ground offense | Aggravated indecent assault (§ 3125) sits above this | Aggravated indecent assault (§ 3125) sits below this |
| Often charged together | Frequently paired with § 3124.1 from the same incident | Frequently paired with § 3126 from the same incident |

Which one fits your case.
When the conduct alleged is contested
Because the two statutes turn on different conduct — contact versus intercourse — the most important early question in a case charged under either one is exactly what conduct the Commonwealth can actually prove, since that alone can determine which statute properly applies.
When both charges are filed from one incident
Where § 3126 and § 3124.1 are charged together from the same event, working toward a resolution that reduces the case to the lower offense, where the facts support it, is often the single most consequential negotiation in the case.
When aggravated indecent assault is the real middle ground
Section 3125 covers penetration without full intercourse, and in cases where the evidence doesn't clearly establish either indecent contact or intercourse, that middle statute deserves consideration as the more accurate charge.
When registration exposure is the deciding factor
Because tier assignment under § 9799.14 differs meaningfully between these two statutes, evaluating the registration consequence of each possible outcome — not just the sentence — should shape how a case is negotiated from the start.

FAQ
Frequently asked questions.
Common questions about indecent assault vs. sexual assault in Pennsylvania.
No — neither § 3126 nor § 3124.1 requires proof of forcible compulsion; that element applies to the more serious offenses of rape and involuntary deviate sexual intercourse under §§ 3121 and 3123.
Section 3101 defines both terms, and the distinction turns on what conduct actually occurred, which is often the central factual dispute in a case where both statutes are potential charges.
Prosecutors sometimes charge both to preserve options if the evidence at trial supports one conduct element more clearly than the other, which is why negotiating toward the lower charge, where appropriate, is a common defense goal.
Aggravated indecent assault under § 3125 covers penetration without full intercourse, sitting between indecent assault and sexual assault, and it's sometimes the more accurate charge where the evidence doesn't clearly establish either end of that range.
Yes — beyond the sentence, it typically affects the registration tier, the realistic availability of diversion, and how the case is assessed for SOAB or SVP purposes, all of which shape the rest of a person's life well beyond any sentence served.
