A real estate transaction is the process whereby rights in a unit of property (or designated real estate) is transferred between two or more parties, e.g. in case of conveyance one party being the seller(s) and the other being the buyer(s). It can often be quite complicated due to the complexity of the property rights being transferred, the amount of money being exchanged, and government regulations. Conventions and requirements also vary considerably among different countries of the world and among smaller legal entities (jurisdictions).
