Have the same owners lived there all that time? That is quite a long time. Of course, laws change and things may be different over the years, but basically a pool has to appear on the certidão at the Conservatória do Registo Predial and on the cadernetas at Finanças, as it will also affect the IMI rateable value etc..oh, and any maps, of course. The problem in Portugal is that often people have a tendency to say timescales, which in the end bear no relation to reality. The best thing though, Gary is to keep on the backs of people. I hate having to do that, but unfortunately found it to be necessary, so keep chasing, so they get fed up with you. I can only say what I have found to be true these days. A pool needs to have both a construction and utilization licence from the Câmara Municipal and from scratch sure takes a long time. Just picked up some mail for some friends. They have an illegal pool and one of their letters was an advice about the impending meeting concerning their fine. On the letter it states that the fine will be between €498.80 and €199.519.16 for individuals or up to €448.918.11 for companies. Quite a range!
