Regarding all types of property transactions in Spain the takeover happens according to special routines. Power of attorney are a very effective way to go through with a transaction without being there in person and affecting long waiting times and delays.
There are different ways to give someone a power of attorney. It is either signed in Spain in front of a notary, alternatively in the native country also in front of a notary. In the latter case we at Scandinavian Management design the letter of appointment according to Spanish regulations and norms. Observe that a power of attorney prepared after a Nordic model, in front of two witnesses, is not valid in Spain!
