As a general rule not limited to Title Insurance companies, pleas keep in mind, that usually, foreign companies offering services are either required (banks) to or just do incorporate in the Dominican Republic, even when using the same name (Scotia Bank, Citi Bank, Nestle, Mc Donalds... etc) and logos.
When you deal with these companies here, contracts are subject to DOMINICAN LAW ONLY. Even if you are citizen of the world's most powerful country or of the same country of "origin" of that company or happen to pay with your credit card from abroad. The contract will be written with a DOMINICAN company and are subject to local law exclusively.
Land and title laws as well as laws relative to leans originated from contractors' claims or other creditors may differ very much from those of your county of origin too. So, the issues and thus needs may not be the sames as when dealing with real estate transactions in your country of origin (E. g.: the US where Title insurance is a common tool).
That being said, it HAS been suggested on this forum in the past, that one advantage of using title insurance, where available in this country could include the benefit of an independent professional "Due Diligence". In other words, that IF the title insurance would not accept the risk, it could/would mean, that the deal may have been found questionable or even clearly uncovered as potentially fraudulent. Some even suggested that the cost of such a policy may be equal or similar to contracting a title search by a legal service... and thus, a round deal, as it also includes the policy's protection afterward.
I can't however remember having read of any documented example.
I understand that Steward Title Insurance was being plugged about 2 years ago in combination with some newer luxury development offerings in the South East of the Country involving "US" developers with very recognizable names.
I am not aware that STI has actively sought to offer their services for "generic" every day deals all over the island. If they have done so, they have not been very "public" about it. But then, I don't "see" everything either and I must admit, it's not something I have dedicated much interest to.
