This paper is a reflective text that uses the property and obligations law construct of condictio indebiti as a mirror for a personal methodological development – the shift from a rule-centred understanding, in which every legal institution has its own requirements, to what can best be described as a feel for the system. Its starting point is a period of unusually concentrated property and obligations law, during which the same legal figure arose in parallel in three entirely different roles.
The text is built around these three perspectives on the same material. The specialisation student seeks breadth and maps the argumentative landscape, using Martinson's method of distinguishing normative arguments, factual assumptions and value judgements as a tool for dissecting case law. The student coach is forced to do the opposite – to simplify without losing load-bearing substance, and in that process to articulate what is otherwise taken for granted. The law firm associate seeks direction, sorts circumstances according to what favours and disfavours the client, and is forced to make qualified assessments under uncertainty. As concrete anchors, NJA 2001 p. 353 and NJA 2023 p. 339 recur, read differently in each role.
The contribution of the text lies in the observation that the role determines not only which answers one reaches, but which questions one asks at all. The reasons for judgment do not change, but what one sees in them shifts with the task – and it is only by switching between perspectives that the limitations of each become visible. The conclusion is that legal maturity is not about reaching a point at which the rules have been mastered in some final sense, but about the ability to move between levels of analysis and to be aware of how one's own position shapes the analysis. Property and obligations law thus emerges not as a subject that can be learned, but as a system within which one moves.
