NDA protocol

Hi – I’m developing an electronic product for a client, which I have never done before, and consequently I want to bring in an engineer when it comes to the Structure/ Electronic design phase. The product is basically an upgrade to an existing system, which the client owns the IP on. So my question is this: do I need to have the engineer sign an NDA to get a bid for service - I’m going to need to describe some of the upgrades in detail to get a good bid.

Thanks for your time,

If in doubt… have the engineer sign one. It certainly can’t hurt.
