Upon the grantor entering into bankruptcy, administration or liquidation, most unperfected security interests “vest in the grantor”, which means that they become invalid. Where unperfected security interests vest in the grantor, there is unlikely to be priority competitions between two unperfected security interests because most unperfected security interests would then be invalid (they would have vested in the grantor’s estate).
There are exceptions – many of the “deemed” security interests (transfers of accounts, commercial consignments and PPS Leases) do not vest even if unperfected, provided they do not secure obligations. Likewise, unperfected turnover trusts do not vest in the grantor upon the grantor’s bankruptcy, administration or liquidation. See generally paragraphs 17.2.5 to 17.2.12 of Chapter 17 (Perfection) for discussion.
