Hi @Ayesha27
You can't transfer the listing to any one elses account- it will always remain with you as the listing admin/owner.
You have the possibility to make your aunt a co-host on the listing, but it will still remain yours, with the reviews and finances still tied to you.
The only other option is for you to close the listing on your account and have your aunt create a new listing on her account- this does mean starting from scratch, but it's the only other possibility.
