UK trademark in Spain

I have a trademark for my U.K. product. A Spanish-based friend sells the product for me on Amazon Spain. Can they submit my trademark in order to get brand registry? Will they need a contract between me (the owner of the trademark) and them showing that they have sole right to sell on Amazon Spain?

Answer: if I understood you correctly, either you or your Spainish colleague will have the trademark certificate in their name. If its your company it would make sense for you to attain the trademark in your name and then arrange an agreement with the Spanish seller in case Amazon asks. I’ve seen requests for contracts requested been trademark owners and distributors.
