Which covenant assures the grantee peace from third-party title disputes?

The covenant that assures the grantee peace from third-party title disputes is the covenant of quiet enjoyment. This covenant provides assurance that the grantor will defend the title against any claims made by others and that the grantee will not be disturbed in their possession by someone claiming a superior title. Essentially, it guarantees that the grantee has the right to enjoy their property without interference from outside parties who may assert a claim to it.

Other covenants such as the covenant of further assurance relate to the obligation of the grantor to take further actions to ensure the title remains clear, and while critical, they do not specifically address the direct assurance against disturbances from third parties. The covenant of warranty forever involves a similar promise of defense and protection against title claims, but its focus is more on long-term protection and guarantees. The covenant against encumbrances states that the property is free from liens or encumbrances, which is important but not directly related to the assurance of peace from disputes over the title by third parties.
