Involuntary Deviate Sexual Intercourse

Facing IDSI Charges? Your Freedom and Future Are on the Line

Involuntary Deviate Sexual Intercourse (IDSI) is one of the most serious sexual offense charges under Pennsylvania law. A conviction can carry decades in prison, mandatory sex offender registration under Megan’s Law, and lifelong damage to your reputation and future. At Sheridan Lawyers, we understand the high stakes, and we are relentless in building strong, strategic defenses for individuals accused of IDSI throughout Chester County, Delaware County, and Montgomery County.

What Is Involuntary Deviate Sexual Intercourse?

Pennsylvania law defines IDSI as engaging in oral or anal sexual intercourse with another person:

• By forcible compulsion

• With someone who cannot consent due to age, mental incapacity, or intoxication

• With minors under a certain age, regardless of consent

These charges often arise from allegations of violence, coercion, or impaired consent. Prosecutors pursue IDSI cases aggressively, and convictions often result in first-degree felony penalties, including 10–20 years or more of incarceration.

Penalties for IDSI in Pennsylvania

A conviction for IDSI can result in:

• Lengthy state prison sentences (often 10–20 years or longer depending on circumstances)

• Lifetime Megan’s Law registration as a sex offender

• Collateral consequences including loss of employment, custody rights, and housing opportunities

• Permanent felony record, making it nearly impossible to move forward

Because IDSI carries some of the harshest penalties under Pennsylvania law, it is critical to act quickly and retain a defense team that knows how to fight these cases.

Defense Strategies Against IDSI Charges

Every case is different, but at Sheridan Lawyers, we explore every possible defense, including:

• Challenging credibility of accusers and witnesses

• Examining medical, forensic, and digital evidence for weaknesses or inconsistencies

• Arguing lack of intent or consent issues

• Raising constitutional violations such as illegal searches, coerced confessions, or flawed police procedures

• Presenting alternative explanations for alleged injuries or circumstances

We know that false accusations do happen, and even when there are complicated facts, our role is to ensure your rights are fully protected.
