  Examining a 20th-century Scandinavian legal theoretical tradition, we can
extract an ontological naturalistic, a logical empiristic, and a modern
idealistic rationale. We introduce the mathematical syntactic figure present in
the `logical empiricism' in a contemporary mathematical logic. A new formal
framework for describing explicit purchase statutes (Sweden) is gradually
developed and subsequently proposed. This new framework is based on a
many-sorted first-order logic (MFOL) approach, where the semantics are grounded
in concrete `physical' objects and situations with a legal relevance.
Specifically, we present a concrete formal syntactic translation of one of the
central statutes of Swedish legislation for the purchase of immovable property.
Additionally, we discuss the potential implications that a subsequent
development of such formalisations would have for constructing artificial
agents (e.g., software) that can be used as `co-creative' legal assistance for
solving highly complex legal issues concerning the transfer of property, among
others.
