What legal term describes a non-consensual sexual act that violates a person's intimate boundaries?

The legal term that describes a non-consensual sexual act violating a person's intimate boundaries is sexual battery. This term specifically refers to any unwanted and unlawful physical contact of a sexual nature. It underscores the absence of consent, which is a critical element in characterizing the act as battery.

In contrast, indecent assault typically refers to acts that are inappropriate or offensive but may not always reach the threshold of sexual battery, which involves direct physical contact. Sexual harassment pertains to unwelcome sexual advances or behavior that creates a hostile environment but does not necessarily involve physical contact. Aggravated assault, while a serious offense, generally involves causing serious bodily injury or the use of a weapon, and is not limited to sexual contexts.

The definition of sexual battery aligns more closely with the concept of violating someone's intimate space through a non-consensual act, making it the most accurate choice for describing this type of violation.
