In order for multiple users to have full access to the same sub-account and the money within it, Shared Spaces uses a Power of Attorney legal model. This means that the premium account holder that originally created the shared space is the sole owner of the space. They grant Power of Attorney to the other participants, giving them permission to transfer money in and out.
The owner of the space can review this “Terms of Use” screen before they invite other N26 users to join. You can also access this when a participant accepts an invitation to join a shared space. You can find these full Terms of Use [here](https://docs.n26.com/legal/02+AT/013+Spaces/en/02spaces-shared-info-poa-en.pdf).
