Cooperation can take many different legal forms. It can be more transactional or more collaborative, more egalitarian or more hierarchical, more process-oriented or more results-oriented, more profit-oriented or more ideal-oriented. And it can also try to reconcile rather conflicting goals.

Therefore, the law of cooperation is inevitably a cross-sectional subject from the law of obligations, corporate law, labor law, intellectual property law, competition law, antitrust law, tax law and others.

Each cooperation is individual. Therefore, their legal form is also to be determined individually and continually to be determined further.
