Order Forms that Need to be Completed by Multiple Parties

I have an order form that needs to be completed by two different parties before it is submitted to me. Party #1 needs to fill out their information -- and then Party #2 can complete the form.

Is it possible for a form that has been partially completed by one client -- to be saved and accessed by another client -- so that they can complete the form -- before it is submitted to me?

Thanks for your assistance.
