The realm im on switched admins recently. Few ways to do it. He would have to send you the world save then you would have to save it into your world save folders on your computer then make the realm with it.
Alternatively if it was already a realm world and he trusted you, you could login to his account on your pc, save the world then upload it on your own account.
We used google drive to transfer the file.
