The article considers such a poorly studied ground for changing the usual order for calculating the limitation period as the absence of a representative of the incapable creditor. An increased attention to the problem of the influence of the creditor’s incapacity on the running of the limitation period confirms the relevance of the topic. The article contains a brief overview of the problem in the domestic and foreign law. The author supports the idea that the absence of the representative of incapable creditor should lead to a change in the usual order of the limitation period. In support of the given idea the article comprises and evaluates the basic political and legal arguments on the both sides. Based on the results of the study of the issue recommendations are given on the appropriate content and place of the relevant norm in the institute of limitation period in the context of current reform of the civil legislation in the sphere of limitation period.
