The article presents the rules of determining the law applicable to receivables and their assignment indicating possible links between a claim, its transfer and legal ways of securing a claim. It emphasizes that the law applicable to receivables is determined separately from the law applicable to the assignment of receivables and the legal security of a claim (e.g. a pledge or a surety). In some situations, both laws need to be applied jointly.
