After Spain's entry to the European Community, and as a result of the obligatory adaptation to community legislation, its Legal Statute coming into effect in 1991 represented an important transformation in the legal nature of the CCS, in its operational regime and in its structure and internal organisation.

The CCS has its own legal personality and full capacity to act. Apart from being governed by its Legal Statute, regarding its activity, the CCS is subject to the private legal regulation and it must be subjected to the Law on arrangement, supervision and solvency of insurance and reassurance companies, as well as the Insurance Contract Act. From this moment onwards, the CCS ceased to be an autonomous organism and became a state-run company, which today is framed in the category of public business entity, as was configured by the Law6/1997, of the 14 th of April, on Organisation and Operation of the General Administration of the State.
