Inheritance anomalies

[uaruman]

My father died in January 2009. Although he was resident in the Uk (since 1946) he was the holder of a Spanish Passport. He was 90 years old, virtually blind and basically illiterate when it came to the written 'english language'.
It then transpired that during 2006, he had purchased a property in Alicante, using fax, emails and various other attachments which had been downloaded via a computer.

On further investigation it then appeared that a Spanish Will had been made, approximately one year later, which was in direct conflict with the English Will.
(Legally the British Will still stands in the UK). Uk 50/50 Spain 1/6th to me.

The British Bank involved in the transfer of these monies (The Halifax Bank) refused to disclose any information in this matter and are still refusing to disclose the relevant signature in respect of this transaction. This will shortly be part of a legal action.

I have refused to sign any paperwork in relation to the Spanish Will. Until the situation has been clarified as to how a sum of money in excess of 150k euros
reached Spain I have refused to be involved (for reasons which should be fairly
obvious).

I understand that without my signature of acceptance in Spain, nothing can progress any further, although various penalties (I have been led to believe) are now due.

Any suggestions as how to proceed further?
