What legal action might borrowers take to resolve a fault in the title?

The correct choice involves taking a suit to quiet title, which is a specific legal action aimed at resolving disputes regarding the ownership of property. When borrowers discover a fault in the title, such as a claim by another party, an unresolved lien, or any other issue that clouds their claim to the property, they can initiate this legal action to establish clear ownership and eliminate any conflicting claims.

This legal process serves to "quiet" any potential challenges or disputes over the title, hence its name. Once a court rules on a quiet title action, the borrower's ownership rights become more secure and verifiable, providing clarity to future buyers or lenders. This is crucial for ensuring that the property can be freely sold or mortgaged without the threat of claims from others.

In contrast, the other options do not appropriately address issues with a property's title. Suing for fraud generally involves a misleading act that results in damage, which doesn't directly resolve title disputes. Filing for bankruptcy is a process for dealing with overall debt rather than addressing specific property title issues. Obtaining a restraining order relates to preventing an individual from certain actions, which does not pertain to clarifying ownership of property.
