Need for Title Insurance
First, before knowing if you need title insurance you first need to understand how this policy works. First, you should look at the chain-of-title and how different title companies do the search on public records. Insurance companies are not quite concerned with what roamed the place or what tribes trekked the lands and what ancestors settled in the location. The search for titles begin only with the time the government came to claim the land, which is not really theirs in the first place, and onwards.
Because of being involved in recording and documenting property transfers, things regarding these matters can sometimes go wrong, and title insurance is what you need to protect you from these unfavorable circumstances.
