A power of attorney is a document signed with a Notary Public where a donor gives powers to another person (wife, lawyer…) for specific actions.
With this document, the attorney is legally authorized to carry out the powers stated in the document on behalf of the donor.
You will need a power of attorney for different actions:
a) If you need to file a claim, you will need to sign a power of attorney on behalf of your lawyer and the Court Representative (Procurador)
b) If you would like to buy a property in Spain and you will not be able to be present at the Notary for signing the title Deeds. Then you should sign a power of attorney on behalf of your lawyer or on behalf of the person representing you in the purchase.
c) If you need to inherit a property in Spain and you cannot come to the Notary.
The power of attorney can include wide powers for each specific case; for example: appearing in Court on behalf of the donor, opening bank accounts, buying properties, allocating inheritances, requesting the NIE number…
You can sign the Power of Attorney in Spain with a Spanish Notary. The Notary will have to be instructed with the contents of the POA. The document will be written in Spanish so you will have to bring a translator with you.
You can also sign it in your country in front of a Notary Public. Your Spanish Lawyer will draft the POA in English and Spanish; then you should sign this document with the Notary and legalize it with the Apostille to make it valid in Spain.
