Which of the following is a reason for a title search?

A title search is primarily conducted to confirm the legitimacy of the seller's ownership of the property. This process involves examining public records to establish the legal ownership of the property and to identify any claims, liens, or other encumbrances that may affect the property's title. By verifying that the seller actually has the right to sell the property, potential buyers can protect themselves from future legal disputes or claims against the title.

The other options, while related to real estate transactions, do not pertain directly to the core purpose of a title search. Identifying potential buyers is typically part of marketing strategies rather than the title examination process. Determining the commission for the agent relates to compensation structures that are established in the listing agreement rather than concerns about ownership. Evaluating future property taxes is a separate consideration that involves assessing the value of the property and local tax regulations, which are not the focus of a title search. Therefore, confirming the legitimacy of the seller's ownership is fundamental to ensuring a clear and marketable title.
