We also obtained our NIE number via our Abogado. When we went to the place in Murcia, our Lawyer came with us and with all the forms pre filled out. The man at the desk did not seem to speak a word of english, so i am glad we had her with us. Then we got a form back from him, you then have to go to the bank pay a fee and get a receipt you have paid, then go back with the receipt to prove you have paid the fee, then they issue the NIE number the next day. Our lawyer did the bank trip and the later visits, we only had to be there for the first visit to sign the forms in the presence of the man, and also show our passports. We went along at about 1100hrs as that is seemingly when the queue is the shortest. We only had to wait about 10 mins. Seeminly the queue first thing in the morning is long as most people go early to try and be at the front of the queue. Our Lawyer is Gomariz Lawyers on +34 968 29 63 99 who are based in Murcia. They have been excellent so far.
