I don't think this requires any notary.
However, if any work reference is produced from colleagues then it has to be explained with as much as details as possible as to why the required format ( from HR or Manager) was not produced.
If case of HR refusing to furnish requested details, an email conversation with the HR can be attached as proof to show that you have tried to obtain the required details.
