House Insurance Ireland If You Buy A House And The Seller Says That The Sale Will Be Done Through A Title Company, What Does It Mean?

If you buy a house and the seller says that the sale will be done through a title company, what does it mean? - house insurance ireland

We in Ireland and unfamiliar with the American system. Who pays what? If the seller pays the company or the buyer? Or is it that distinguishes them. The house is located in Detroit.

We have heard the "Title Insurance is, what do the title company? That all closures made by a title company will be sent to the security instrument (the highest form of protection for buyers in the U.S. I think?)

Thanks
