I agree, but it's very aggravating and takes forever "sometimes". We own two connected parcels, that we bought separately. They were both part of a huge parcel that one family originally owned, now it's owned by about 5-6 of the children, some of whom have died and the others are ancient. Next door neighbor is 100. We bought it all in the late 70s, early 80s.
The first parcel has the house, well, etc., on it. We started the deslinde process in Feb 2015 on that parcel. As of today, we still don't have it. We don't anticipate problems, in fact we've been told it was approved, but it drags on and on.
The second parcel will be the problem, it's supposed to have 9 tareas, but when it was surveyed it's actually 8. We told them to title it as 8, and they said 'no, we have to find the other tarea'. The property is fenced, can you just SEE us trying to convince a Dominican neighbor that they have one of our tareas???
Long story short... 1. Do NOT buy a property without a deslinde. And, 2. If you think you're going to sell your property within the next 5 years, start your deslinde NOW.
