Del. Code Ann. tit. 6, § A-306
Subject to subsections (b) and (c), Article 12 determines the priority of conflicting claims to Article 12 property when the priority rules of Article 9, as amended by the amending Act, do not apply.
Subject to subsection (c), when the priority rules of Article 9, as amended by the amending Act, do not apply and the priorities of claims to Article 12 property were established before August 18, 2023, law other than Article 12 determines priority.
When the priority rules of Article 9, as amended by the amending Act, do not apply, to the extent the priorities determined by the amending Act modify the priorities established before August 18, 2023, the priorities of claims to Article 12 property established before August 18, 2023, cease to apply on the adjustment date.
