Title risk

Liens that survive the sale

Certificate stage does not clear private liens. After redemption and collector’s deed process, most junior private liens may be cut off; federal and some governmental liens can survive. First/second/third offering structure under RSMo Ch. 140 applies.

Quiet title

Petition for collector’s deed required; quiet title often still used to strengthen insurable title for resale in the north KC market.
