In my opinion, and this is MY opinion, a lawyer for almost anything to do with moving to Portugal is just an overpaid secretary. Unless you are buying property here, there really is no need to get one, IMO.
Things a lawyer ill do for you:
1. Collect and file paperwork to get the temporary Visa (4 - month) before move. You will still need to fill out the paperwork and sign it. Since you have to do that, you can easily collect it yourself and file it yourself at your local Consulate in the States.
2. Obtain a NIF number. There is an office in just about any decent sized town. You need your passport, driver's license, social security card, and a Guarantor, plus the fee and about 1 hour to 90 minutes of time. It definitely will help if you speak the language or have a translator with you, but it can be done with Google translate. Everything but the Guarantor is you, so you might as well do it yourself. A guarantor is a Portuguese person that will sign for you saying that you will pay your taxes for the following year. After you pay once, you no longer need a Guarantor. A lawyer could do this, but if you know anyone local, they can do it for you. We hired a college student to be our translator for 4 hours one day and he signed for us.
3. Open a bank account. You need your passport, a NIF Number and a permanent address (can be US or other country - our's was in the US when we opened our bank account. Again, a translator is helpful, but Google translate will work too. Took about an hour including the wait time.
4. Review rental contract:. We used a local realty for finding an apartment. The agent spoke English. We had copies of the rental agreement made in English and in Portuguese. We just read over the English one to see if was to our satisfaction and signed it and the Portuguese one. We used Google Translate to verify any questions we had in the English version was the same in the Portuguese version.. if you use a realtor, they have very standard rental contracts just like we do in the States
5. Review Purchase Agreement. We did not buy, so this didn't apply to us. Here is the only place I could see a lawyer being necessary, just like in the states. I don't know the laws of ownership, plus title transfers and liens and such. But, IMO, you shouldn't buy until you've been here a while as you don't know the neighborhoods, towns, etc until you've been here. If you buy first thing, you are basically stuck. We love our apartment and city, Braga, , but we've visited a couple of other cities now that also hold charm and possibility so we might decide to move in a year or two. By renting, we still have that flexibility.
6. File and obtain Long-term Residency (Visas): If you done all the above (1-3 and one of 4 or 5), you've got all the paperwork necessary to file for the first 1 year Resident Visa. Just make an appointment at your local SEF and bring all of it. Our appointments are in March. We will not be using a lawyer. Before the year is up, you make an appointment to renew the 1 Year Visa to a 2 Year Visa, along with the same paperwork, Then before the 3rd year is up, do it all again, Before the 5th year, do it again, plus pass a Portuguese proficiency test. After that you are a permanent resident.
The entire process is a little time-consuming, but not that difficult. And if you are moving here to be retired or without a job yet, you have the time. The savings I am getting are well worth a few hours of my time.
