We have customer set up somewhat like this:
Williams & Smith Partnership
D/B/A WS Granite and Stone

A loan officer just did a loan with them and has taken equipment as the security. He filled out the UCC filing paper using WS Granite and Stone as the filing name. Wrong, right? how can we file a UCC under "doing business as".

I would assume we would file under the Partnership's name since that is what has the Tax ID #(filed with the state)?!?! But then the loan clerk tells me that actually the equipment we took as security is actually only owned by one of the partners so do I then only file under the owner of the equipment?

UCC's and Article 9 are somewhat a new area to me so any suggestions would help. I'm just not sure which direction to take so we can make sure we are perfected.

I think you need to visit with your attorney and call in this loan officer for some training with the attorney present. I see a lot of things potentially wrong with this whole mess that transcend the wrong name on a UCC.
