HELP - In what document....

Hi, I'm doing a college assignment and can't for the life of me remember where this information is located.

I need to know where it states that child's records, etc should be kept until the child reaches 21 years of age?

Or if I'm wrong, the correct age please?

Thanks
Elli

Oops link didn't work

It is for your PLI insurance Company because a child has three years from the age of 18 to make a claim in their own right as a result of an accident when in your care.

Thank you!

I knew I'd read it somewhere!
