As the 'Lead' or 'Admin' parent, you can add a 'Co-parent' to manage your Junior account together with you. This is set individually for each Junior account. To assign a Co-parent, open the Revolut app, go to the Junior tab, select the Junior account you want to add a Co-parent to (if you have more than 1 linked Junior account), scroll down to the 'Parents' section and select 'Add a Co-parent' option.
You can remove the Co-parent at any time by selecting the Co-parent in the 'Parents' section of the Junior account and selecting the 'Remove' option.
You can only assign one Co-parent at a time, and you can reassign the Co-parent up to maximum of three times per calendar year.
