Civil Weddings

It is possible to have a civil wedding in Spain. However, be forewarned that you do have to meet some residency requirements.

Thus, unlike a Catholic Wedding, you can not just show up in Spain and hope to have a legal wedding because there can be a lot of provisional paperwork to go through beforehand.

If you have been on the Padron in Spain for two or more years, then it should not be problem

Symbolic Blessing
By far the most popular option taken by couples fro the UK and Ireland is a Symbolic Blessing.
With few exceptions (we need special permissions for Beach Weddings, for example) these can take place anywhere and a lot of Salones de Bodas are specially set up for this function.
We have contacts with former ministers and clergy from the UK and Ireland and, if you promise to keep it a secret, I'm also a minister, but not many people know that!

A symbolic blessing is exactly the same as your church service.
The only difference is that the paperwork is symbolic. Everything else is as a legal church ceremony.
If you don't tell anyone beforehand, not one of your guests, not even your parents, will know the difference, unless you tell them.

The most popular options of legalizing your Blessing are to have a Civil wedding back in the UK or Ireland, or visit Gibraltar for the day.
