Certain defects can remain hidden, despite the most thorough title investigation Various irregularities may occur in recorded documents or in the circumstances surrounding these documents (i.e. invalid documents, forged documents, typographical errors, lack of authority by those signing the documents, documents signed by incompetents or minors, documents affected by undisclosed marital status, documents affected by death, documents executed under fraud or duress, etc.). In addition, various irregularities are not disclosed by documentation (i.e. county clerk error, misapplied payments, missing information, etc.). This can result in problems that cannot be uncovered by your attorney. Many such problems may not be discovered for years.
