Hi glan and welcome to the forum
What are the grounds for annulment? Mistake or payment in full?
As a bankrupt you are not allowed to be involved in the formation, promotion or management of a company without the Trustee's permission. So even if the company was based in Spain you would be defaulting on this provision.
Best thing to do is pursue the annulment. If it is based on mistake, then try and find a lawyer to represent you as this is a specialist area of the law and to be honest people representing themselves are rarely successful - and if you win you will get costs awarded to you.
