The five covenants discussed do not by any means guarantee a marketable title to the purchaser. The purchaser may have much actual trouble with his title and possession, yet no covenant be broken. There may, as said, be some person or persons making claims to rights in the property. If however the purchaser is not actually put out of possession he has, in New York and many other States, no redress; neither the covenant of warranty nor that against encumbrances has been broken. There are many technical defects which may exist in a claim of title or possession not sufficient to permit of ousting the purchaser, nor of constituting a breach of any covenant, but which nevertheless are a cloud on the title. Under such circumstances the purchaser has what is known as a "good" title; no one can take away his possession; but he has not a "marketable" title; he could not compel a purchaser to take it.
