Such a discrepancy is often due to logistics. If z.B. the closing date of a reservation expires one or two days from the scheduled date, parties may prefer not to change the date in each booking letter. And if one party signs a contract on a certain day and then mails the contract to the other party to sign, the date of the introductory clause could be the date on which the first party signed or another date. In addition, a contract is considered valid only if all the necessary parties sign it. If z.B. the lease deadline is September 1, but today is September 3 and the necessary parties have not signed the contract, it is invalid. Often, a contract is entered into and dated on the day of the last signing (as explained above), but contains a different and defined “effective date” indicating when some or all of the parties` obligations must begin. This date may be in the future or in the past – whether a treaty can create or confirm rights related to past events is a matter of interpretation. This means that even if you signed your lease months before moving in, you don`t have to keep the unit clean, pay rent or anything else until your lease actually starts (unless something in your contract determines otherwise). Conversely, you cannot live under the premise until it comes into force.

Contracting parties can be negotiated for months before the contract date and then designate the effective date of the date on which they began negotiations. In this case, the parties may assert, from the date of the contract, the retrodated rights that began on the fixed date of entry into force. The effective date of the contract is designated as the effective date (or effective contract) that may differ from the date of execution. This date cannot be set before the execution date, i.e. a contract can only be in effect after all parties have signed it. By signing the contract, all parties declare that they agree on the effective date. It is important to remember that the retrodedatation of the defined validity date is not the same as the retrodedation of the contract itself. The retro-relationship of a contract may constitute a criminal offence and a violation of the rules governing the professional conduct of lawyers. There are some interesting legal points that arise from the ability to have a date backdated. The execution date is the date on which both parties sign the contract.
