updates to a template purchased on themeforest

Hello, I am going to purchase a template (optima) to create my site on wordpress.org. I want to know if in the event that this template has updates in the future, I will have to pay for the update to prevent my site from becoming obsolete or malfunctioning. I have spoken with the author of the template who tells me that template updates will always be available on Themeforest and my question is: in the future will I have to pay themeforest for updates to my optimal template? Thank you

In most cases, no, the updates are free but you may need to extend your support in some cases.
