Mr. Cotten and Mr. Williams, I would be interested in any elaboration you can do on this subject. In my own limited experience I have learned that for the purpose of leasing that some companies will settle for considerably less than proof of marketable title. Does covenant of seizin mean that any lease signed without clear title could be cancelled and subject to return of bonus? It would seem the lessee should be responsible for his own due diligence or lack thereof. I guess you can learn an expensive lesson by failing to read the fine print.
