Can someone else remove my Acrobat watermark?

[Mrs.Jessica Hill]

If i send a document with a watermark, can someone else remove it if they have advanced adobe?

One way or another, surely. There are many PDF editors, not just Adobe.

If I am sending something that is an unfinished product, I will add the watermark; so once its paid I will send a copy without the watermark; So I was wondering if I was stabbing myself in the foot by doing it that way; I thought it was more secure.

It's not, but if you want to make it more difficult (although not impossible!) to remove it apply a security policy to the file, with both Edit and Open passwords. Make sure to use different ones, of course. You will need to supply the latter to the person opening the file, and keep the former to yourself.
