The aim of this master's thesis is to examine how the general prohibitions and special norms provided by Estonian law restrict the freedom of the parties to restrict or exclude liability for breach of contractual obligations, using the provisions of the sales contract as an example. We also examined the relationship between LOA § 106 (2) and other provisions enabling the limitation or exclusion of liability, and which agreements on the exclusion and limitation of liability are permitted in the sales contract when formulating the standard of liability, presumptions of remedies and content of remedies.
