In many cases the breach of contract may give rise to delictual liability since the damaging behaviour can be construed as unlawful, especially when an infringement occurs of the other party’s rights in rem or physical injuries are caused to the contract partner as a result of such a breach of the contractual rules. On the other hand, there is no place for delictual liability if the damage results from a breach of a contractual obligation which is part of the consideration. Examples of the relationship and concurrence of delictual (tort) and contractual liability for the breach of contract, legal aspects of interference problem, peculiarities of tort law and contract law, their specific regimes and the areas of possible overlap are analyzed in this work. The issue under consideration is whether a plaintiff who has a contract with the defendant and who can also establish a tort relationship with the defendant may have a choice of remedies in order to gain some advantages with respect to a burden of proof, degree of fault, availability of exceptions, or length of the respective periods of limitation.
