Turning 18

Turning 18 can have a significant impact for any child involved in a criminal case.

Which court?

A child who turns 18 during a criminal case can continue to have their case heard in a youth court.1

If a child turns 18 before their case gets to court, their case must be dealt with by the adult courts.2


If a child turns 18 after they plead guilty or are convicted, but before they are sentenced, they are entitled to receive youth sentences and a court must impose a Referral Order if the compulsory conditions are met.3 Even though this creates practical issues in relation to supervision of Referral Orders and Youth Rehabilitation Orders.

If a child turns 18 before they plead guilty or are convicted, they cannot receive youth sentences but the child’s age at the time of the offence must be taken into consideration.4 Courts must follow any sentencing guideline unless it would be contrary to the interests of justice to do so.5 The Court of Appeal has also empahsised that turning 18 is not a ‘cliff edge’ and age remains a relevant factor for young people.

It can therefore be very important to avoid delay if a child is approaching their 18th birthday in a criminal case.
