In Spanish law, the «rebus sic stantibus» clause, of creation and jurisprudential development, can be raised exceptionally in situations in which contractual circumstances change unexpectedly and produce an excessive onerousness for one of the parties. This paper analyzes this clause and the changes experienced in the most important jurisprudential resolutions recently issued. It also raises the use of mediation to try to get the parties to reach an agreement and renegotiate the contract, whether the clause is applicable or not.
