As you can see, the issue of backdating can be controversial. This is not easy and can cause problems for any lawyer who agrees to date a document, even if they clearly indicate on the document that it is demoted, as they must ensure that they know why the document is being retrodated and that it is done for a legitimate reason. It is therefore preferable, in case of doubt, to say « no » or, if necessary, to resort to external legal advice. Is it already normal to return a document? There are rare cases where this can be allowed or even justified. A frequently used example is when the parties had originally signed a document, but the original was lost or destroyed before it could be stamped or submitted. In such cases, it would be entirely appropriate for the parties to re-execute an identical document in order to replace the missing document.
