Antedating refers to assigning a date to a document that is earlier than the actual date it was created. This practice can have legal and procedural implications and is often compared to post-dating.
To insert a date on a document that is later than the date on which it is signed, making it effective only from the later date. A post-dated (or forward-dated) cheque cannot be negotiated before the date written on it, irrespective of when it was signed.
