Yes. You grant us a notarial power of attorney and our representative acts for you in Spain: buying or selling a home, accepting an inheritance (yours alone or the whole family's), applying for your NIE or filing documents with the tax office. We advise you with our partner lawyers and file the taxes that apply.
You sign the power of attorney in your own country, at the Spanish consulate or before a local notary with a Hague Apostille. If the power is for a specific act, it can also be signed by video conference before a Spanish notary, as Law 11/2023 allows.
The exception is strictly personal acts: a will, for example, is always made in person.
