Re Brightlife Ltd [1987] 1 Ch 200 is a UK insolvency law case, concerning the conversion of a floating charge into a fixed charge ("crystallisation"). It held that an automatic crystallisation clause was part of the parties’ freedom of contract. It could not be limited by court created public policy exceptions. The significance of the case was largely outpaced by the Insolvency Act 1986 section 251, which said a floating charge was one that was created as a floating charge.
