Legal age of consent

What is the legal age of consent?

The law says that a person must be 17 years of age to be able to consent to engaging in a sexual act. This means that a young person under the age of 17 is not legally old enough to consent to a sexual act even if they want to. Remember, it is a crime to engage in a sexual act with someone who has not, or cannot, give consent.

The age of consent is the same for males and females and for homosexual and heterosexual sexual acts.

Does this mean that two young persons are breaking the law if they engage in a sexual act?

Not necessarily. The law recognises that younger people may be engaging in sexual activity with each other and has introduced a ‘proximity of age’ defence. This is sometimes call the “Romeo and Juliet Defence”. This means that if a person has been charged with an offence of engaging in a sexual act with a person between the ages of 15 and 17 years he or she can put forward a defence but only if all of these conditions apply:

  • the age difference between the two parties is not more than two years
  • agreement was given freely and voluntarily
  • neither party felt exploited or intimidated
  • neither person is a person in a position of authority

So, for example, this defence may be open to two 16 year olds, or to a 16 year old and an 18 year old, but only if all the conditions above are present. It may ultimately be up to a court of law to decide if there was actually free and voluntary consent in these circumstances.

The law in this area is complex. The consent of the Director of Public Prosecution is always required for any prosecution of a child under the age of 17 years.

It is advised that where any formal charges have been brought around underage sexual activity, even where it does not appear to be abusive, legal advice should immediately be sought.

Persons in positions of authority

It is a serious offence for a person who is, or has previously been, in a position of authority over a child, to engage in a sexual act with a child or young person who is under the age of 18 (regardless of the fact that the legal age of consent is 17). Such a young person can never legally consent to engaging in a sexual act with a person who is, or who has previously been, in a position of authority over them.

A full list of persons considered to be in a position of authority is set out in the law, which includes, for example, family members, carers, teachers and sports coaches.
