Can I sell wordpress theme from psd file that I buy on theme forest?

Hello,

Can I sell wordpress theme on themeforest that I create from psd file that I buy on themeforest?

Not without permission from the original author

Thank you for your reply. Do I need to pay for the permission or just ask the author?

You need to ask permission, you will probably need an extended license and the author may want profit sharing / one-off payment, etc.

The author needs to submit a ticket to Envato saying that they permit you then give you the ticket id to include in your submissions

OK. Thanks a lot for the information.
