Planning for your child's transition to adulthood should begin when your child is 13 or 14 years old, so that by the time they are 16 you are both ready to think about making decisions about the future.
When your child turns 16, they can have more say in their education. When they turn 18, they become a legal adult. One thing this means is that they can make their own decisions about their life unless they ‘lack mental capacity’ according to the Mental Capacity Act 2005. Mental Capacity is decision specific. This means the person could have capacity to make some decisions, but not others. If your child or young person lacks the mental capacity to make a particular decision, any decision made on their behalf must be made in their best interest.
