This 'JISA Graduation' process is automated. When the child turns 18, they are automatically set up as a client in their own right and the JISA will convert to an ISA. The client record will first show as registered, and the account will show as Pending. 

At this point you will be able to access the registered client record and enter their additional details, to include their email address. This will result in a registration email being sent to the new adult holder, and they will need to log in and accept the platform and ISA terms. KYC, AML, ID and Bank checks will be completed automatically at this point.

The Client and Account records will now show as Active within the system and the client can choose to withdraw, transfer, or continue to invest their funds within their Stocks and Shares ISA.

Please note any ongoing payments that were being paid into the JISA will cease and these will need to be reinstated on the new ISA account.
