Prisoners' families & children Children & young people For young people Teen FAQs Can I visit my family member? If you are under 16, you will need an adult to accompany you to prison. This adult does not have to be a relative. If you are aged 16-18, then you might be allowed to visit without an adult, but sometimes there are reasons why this is not allowed. If you do visit alone, you will need written permission from your parent/guardian.
