The Sexual Offences Act 2003 (c. 42) is an Act of the Parliament of the United Kingdom.
It partly replaced the Sexual Offences Act 1956 with more specific and explicit wording. It also created several new offences such as non-consensual voyeurism, assault by penetration, causing a child to watch a sexual act, and penetration of any part of a corpse. It defines and sets legal guidelines for rape in English law. It is also the main legislation dealing with child sexual abuse.
The corresponding legislation in Scotland is the Sexual Offences (Scotland) Act 2009 and in Northern Ireland the Sexual Offences (Northern Ireland) Order 2008.
