I would
never recommend doing it yourself, certainly not for the first title search on a property. It has to be a good, experienced, upright lawyer. Backed by title insurance, if you choose.
What you
can do yourself and I have done, is to check that someone hasn't put a lien on your title unbeknownst to you, several years after you first obtained it. This isn't difficult or expensive, just time consuming - you pay taxes at the DGII and go along with a
solicitud, copy of title, cedula and some other documentation and request a search. I do this every few years - 'damage control'

. It also gets the word around the Land Registry that this particular title gets periodic checks, so if there was something going on like happened in Bavaro/Higuey a few years back, it wouldn't be worth anyone's while to try to 'obtain' your title.
