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. Knowing the difference between the two data is essential to ensure that you process your contracts correctly. You will understand when your role in the treaty comes into force and you will protect against possible legal action. A document backdated to obtain a more favourable legal result is probably illegal. For example, if a document is signed in January but goes back to December to get some tax deduction, it is probably illegal and can be criminal. CONSIDERING that the parties now wish to conclude this contract, which dates from 15 July 2018, referring to the oral agreement of the parties and taking into account the additional conditions provided by the proposal; First, the validity date is sometimes used to refer to the date indicated in the introductory clause, as in this example – which I did not clean, even though I changed the names – in the SEC`s EDGAR database: the date of consent. Sometimes the discrepancies described between the date of signing and the economic effectiveness of a contract can only be corrected by requesting the return of the documents or by changing the other party. In these cases, it may be interesting to keep in mind that the meeting of minds or acceptance of the last offer was probably even a few days earlier. This means that the (oral) agreement already existed and could be useful for the development of a document. There are some interesting legal points that arise from the ability to have a date backdated.
In other cases, the parties may enter into a transaction orally “in hand” with the intention of concluding a written agreement at a later date. Many years ago, one of my clients had to borrow $1 million. To my surprise, a benevolent lender wired the money to the customer without having credit papers on site, but with the hope of obtaining a debt note at a later date. “This contract is August 31, 2018 (effective date), although the parties may have executed it before or after that date.” Sometimes a document has to be backdated to make it correct. Suppose a creditor starts delivering his product under a proposed contract to determine later that the customer never signed the contract. In this case, the insertion of the date on which the parties started the performance under the contract is more precise than the date of signature to be inserted. The agreement begins on [the date of this agreement] and continues for a period of  years and is subsequently terminated. When signing your next contract, take the time to read the document carefully. Now that you know the difference between a validity date and an execution date, make sure the document shows exactly when it will come into effect.
The date of the contract – good practices. Be careful with the date of the agreement: if the agreement has coverage, there will probably be a date and contract lines will also include a date in many cases. In addition, the signing words of the agreement (just before the signature blocks) often contain a date and many signatories will write a date next to their signature (despite the fact that there is no reserved space). Make sure that at least the printed data is all the same; but preferably to avoid confusion at a later stage, insert a validity date only once. The validity date can be used to indicate a date in the future. This is often used in employment contracts that link the validity date to the date the employee starts working. But as Ken Adams said, “I am not misleading to ensure that the effectiveness of the agreement is linked to the date the employee will take office, because the agreement will be effective once the parties have signed it.” Although this is not the case
