If there has been a foreclosure by another competing creditor upon the same debtor that your company is seeking to collect against, the other creditor was first in time to collect upon the assets of the debtor before yours and there seems to be nothing that you can do as to the assets collected upon to date unless your company was in a higher secured position as to some if not all of the assets that were previously obtained.Your company's recourse is to go after other assets of the debtor that have yet to be levied upon by a competing creditor that you have written about.I recommend that you consult with an attorney who practices in the area of debt collection for creditors.Good luck.
