(2) If the claimant is a lien claimant, the notice must reflect the nature of the lien claimant’s interest and the claimant shall attach to the notice copies of any documents necessary to establish that interest. If the claimant is a successor in interest to another person with redemption rights under ORS 18.963, the claimant shall attach to the notice copies of any documents necessary to establish how the person acquired the interest. If the claimant claims to have an interest with a priority that is superior to the interest of the certificate holder, the claimant shall attach to the notice copies of any documents necessary to establish that priority.

(3) A redemption notice must be served by personal service or by first class mail. If the notice is served by first class mail, service is effective on mailing. A copy of the notice may be filed with the sheriff before the notice is given to the certificate holder, but must be filed with the sheriff no later than seven days before the redemption date specified in the notice. The notice must be served on the certificate holder not more than 30 days before the payment date specified in the redemption notice, and:

(a) Not less than 14 days before the payment date specified in the notice, if service is made by first class mail; or

(b) Not less than seven days before the payment date specified in the notice, if personal service is made.

(4) A claimant shall submit proof of service of the notice required by this section at the time the claimant pays the sheriff under ORS 18.975.

(5) If a certificate holder fails to comply with the requirements of ORS 18.930 (6) or 18.982, the certificate holder may not object to a redemption by reason of failure to receive a redemption notice. [2005 c.542 §44a; 2007 c.580 §3]
