Legacy Court Fine

[Unregistered]

3 years ago when I was holidaying in Spain I was arrested and was asked to provide my parents address so a fine could be sent by the judge. I provided all the details and was released and allowed. Oto continue on my holiday. Since then I have not returned to Spain but have received no paperwork in the post and have moved house. My question is what to do about this as it has been hanging over me for quite sometime now, is it better to let sleeping dogs lie or pursue the matter? I wouldn't even know where to begin with it!?

I don't know how efficient the Spanish legal system is but I'm inclined to think that after this length of time it will be of little interest to them?

Any advice would be greatly appreciated.
