Auditors working for the underwriter that recently shut down Nixa-based Guaranty Title Co. believe the company may have misappropriated funds, according to a Missouri Department of Insurance spokeswoman. Guaranty Title was abruptly shut down June 19 by St. Louis-based underwriter Commonwealth Land Title Insurance Co., a subsidiary of Richmond, Va.-based LandAmerica Financial Group. Guaranty operated at least nine title insurance offices in southwest Missouri, primarily in Greene, Christian and Lawrence counties. Guaranty Title is not affiliated with Springfield-based Guaranty Bank. Two auditors with LandAmerica were still analyzing Guaranty Title's financial records at press time.
