In which situation might a title search reveal an undisclosed lien?

The scenario where an heir to the property unexpectedly claims rights can lead to the revelation of an undisclosed lien because it often indicates that there may be additional claims or interests on the property that have not been formally recorded or disclosed in public records. When an heir claims rights to a property, it may uncover previous financial obligations or liens associated with the decedent, which were not cleared or disclosed prior to the title search. This situation emphasizes the complexity of ownership and claims that can arise, particularly when dealing with estates and inheritance.

On the other hand, while renovations (as mentioned in the first option) may change the property's condition or value, they do not typically affect the title or possibility of undisclosed liens. A routine inspection focuses more on physical condition rather than ownership and financial claims. Lastly, payment of property taxes signifies that the property is current on tax obligations, but it does not inherently reveal any undisclosed liens that might exist due to other financial encumbrances.
