The Polish law of contracts is based on the principle of freedom of contracts, under which
parties to a contract may arrange their legal relationship as they deem proper, on condition that
the content or the purpose of that contract are not contrary to the nature of the relationship,
statutory law and principles of community life. Not limiting the general autonomy of the parties
to a contract, the Polish provisions regulate most common types of contracts (sale agreement,
building agreement, lease, tenancy, etc.). It is also possible to conclude a non-defined contract,
the content of which results from individual arrangements (on condition mentioned above).
By arranging the legal relationships, reference should also be made to the rules of many
international conventions and EU law concerning contracts, which Poland is obliged to apply,
especially in the scope of governing law issues, jurisdiction, recognition and enforcement
of foreign judgments and arbitral awards.
