In the contracts with successive enforcement concluded for limited duration, reaching the deadline marks the end of the effects of the relevant legal act, without the need of an agreement on this line from the parties. It is a cessation by right of the effects of the contract. The automatic cessation of the contract at the moment of the settled deadline represents a general principle, valid with respect to any contract, unless a legal provision or a contractual clause contains a contrary provision. An exception from the automatic cessation of the contractual under the mentioned circumstances is also the tacit re-lease.
