What term refers to any claim or encumbrance on the title to a property affecting its transferability?

The term that refers to any claim or encumbrance on the title to a property affecting its transferability is known as a "cloud." A cloud on title can arise from various issues such as unpaid taxes, liens, easements, or any other claims that may create uncertainty regarding ownership or affect the property's ability to be sold or transferred. These clouds must typically be resolved before a clear title can be established and an owner can transfer the property without complications.

While "title defect," "mortgage," and "liability" relate to property and ownership issues, they do not capture the broader implications of a claim or encumbrance on title. A title defect specifically denotes issues that directly impair the legal title, while a mortgage is a security interest in the property used to secure a loan, and liability pertains to legal responsibilities, which may not necessarily affect ownership or transferability directly. "Cloud" provides a more comprehensive description of any potential issues that could hinder the clear transfer of property.
