Not on the island yet?
If the buyer cannot be there for the signing of the final paperwork it is possible to ask a trusted person, for example his lawyer to be their representative at the purchase by a power of attorney (poder). This will authorize them to act on the buyers behalf. The final deed of sale (Escritura) will be signed by the buyer (or their representative), the notary and the vendor. Once the paperwork is signed and witnessed it is then time to pay all sums owing for the property, the taxes and the land registry fees. The lawyer will send all the relevant paperwork to the land registry for the change of ownership, will change the name of the owner in the tax authority, the local town hall, the electricity, water companies as well as with the community of owners.
The new deeds can be collected within about two months from the signing.
