How do I find out when a PDF doc was originally created there is nothing under File/Properties

You ask the creator of the PDF document.

This is a legal case against a defendant who will not cooperate.  She has a date in there of April 7 2015 but I suspect it was created yesterday 8/20/2015

Hi David,

Generally, it is shown under document properties window in Acrobat (As shown in the following snapshot).

However, if the sender/Author has removed metadata from the pdf then there are chances that original file creation date is not displayed.

Hi David,

The sender/Author of the pdf has removed the metadata of this pdf as it is shown by default, the original creation date of this document cannot be verified.

Rahul

Just a note that the metadata is easy to fake. It may be interesting to investigate but could carry no evidential weight if anyone had motivation to fake it.

For actual proof of date, digital signatures are needed - and not just any digital signatures as some rely on the computer's own clock.

So finally, isn't there any way to find out the actual  authentic creation date of PDF file.

No.

Hi do you know a company that could tell when a PDF was originally created? I use the steps that were mentioned above and it tells me the date that I downloaded it 

[try67]

This information can't be relied on. It's child's play to manipulate it to any value one wishes.

[default939f94av04nn]

Yes but I really need to find out the date of this document that it was created of modified 

[try67]

You can look at the file properties or metadata, but again, there's absolutely no guarantee there's any relation between that date and the actual time the file was created, even if you really want there to be...

Your genuine need does not make it technically possible. If you read this thread it should make it clear that even if you have a date in a file, it is worthless for proof of anything at all.
