Seller did not inform Tarrant County, Texas that improvements had been made on the property. Insured purchased the property in 2005. In 2008, Insured received notice of the supplemental taxes assessed for years 2003 and 2004. Insured satisfied those taxes 11/26/2008 and tendered a claim on their title insurance policy. Seller was reimursed 08/27/2009.

Insurance Company is subrogated into the rights of the insured (possibly also the taxing authority). What would be the applicable Statute of Limitations for pursuing the Seller for these unpaid taxes?

Breach of Warranty is 4 years from the date of the warranty so that appears to have passed. Unjust Enrichment is 2 years fromt the date of loss payment, thus that may have passed.  However, is there a limitation for pursuing taxes? Thanks.
