What is the procedure for the transfer of shares in spain?
As a Franchise Attorney I can only say the answer is unknown. Spanish securities laws likely govern any share transfers. The person who is most familiar with Spanish securities law is a licensed attorney in Spain. Consult with a good business or franchise attorney in your area for specific advice.
