Register online during the short Sept. 1 window; pay for extra numbers when Treasurer contacts you Sept. 1–2. Accept or decline assigned liens by 5:00 P.M. Sept. 3 or forfeit to redraw pool.

Title risk

Liens that survive the sale

After tax deed following the long redemption period, most private liens are cut off; federal liens can survive. Certificate stage is lien-only — owner redemption extinguishes the certificate.

Quiet title

Often recommended after tax deed for resale/insurance in Wyoming practice.
