ORS § 94.716
If a lien against two or more lots of the planned community becomes due, whether the lien is perfected before or after establishment of the planned community, the owner of an affected lot may pay the lienholder the portion of the lien attributable to the lot. Upon receipt of payment, the lienholder promptly shall deliver to the owner a release of the lien as to that lot. The amount of the payment shall be proportionate to the ratio which that owner's common expense liability bears to the common expense liabilities of all owners whose lots are subject to the lien. After payment, the association may not assess or have a lien against that owner's lot for any portion of the common expense liability representing the lien. This section applies to all liens except a mortgage.
