Equity [Abstract]
Common Stock and Class B Common Stock	Common Stock and Class B Common Stock. Holders of Common and Class B Common Stock have the same rights except no cash dividends may be paid on Class B Common Stock. The two classes of stock vote separately when electing directors and on any amendment to the Company’s certificate of incorporation that affects the two classes unequally. A provision of the by-laws requires an affirmative vote of at least two-thirds of the directors to elect officers or to approve any proposal that may come before the directors. This provision cannot be changed without a majority vote of each class of stock. Holders of Class B Common Stock may, with no cumulative voting rights, elect four of nine directors if 1,050,000 or more shares of Class B Common Stock are outstanding; three directors if between 600,000 and 1,050,000 shares are outstanding; and none if less than 600,000 shares of Class B Common Stock are outstanding. Holders of Common Stock, with cumulative voting rights, elect the balance of the nine directors. Class B Common Stock may be converted by its stockholders into Common Stock on a share-for-share basis, although the holders of Class B Common Stock have agreed among themselves not to convert their stock. The agreement may be extended or terminated by them at any time. Such conversion is mandatory on any transfer to a person who is not a lineal descendant (or spouse or trustee of such descendant) of William H. Stewart, founder of Stewart Title Guaranty Company. On January 26, 2016, the Company entered into an Exchange Agreement with the holders of Class B Common Stock relating to the exchange of 1,050,012 Class B Common Stock shares, representing all outstanding Class B Common Stock, for 1,050,012 shares of Common Stock plus $12.0 million in aggregate cash. The Exchange Agreement is subject to several conditions, which include, among others, the approval by the Company's stockholders of the Exchange Agreement and the Company's by-laws during the 2016 annual meeting of stockholders and the approval of the listing of the Common Stock by the New York Stock Exchange. At December 31, 2015 and 2014, there were 145,820 shares of Common Stock held by a subsidiary of the Company which are included in the Treasury stock reported in the consolidated balance sheets.
