Read your book and ask the teacher since you are paying them.

Please read Chapter 1, Agency Relationships

I do not see any reaction on the answers you already received. Do you read any of them? 

Time to hit the books?  Seriously you will learn so much more doing your own research, and it will stick in your head.  A

The difference is whether the other party knows it is partially disclosed or undisclosed.  For example, I could tell you that I have a buyer for your property that I am working on the behalf of but his/her identity remains anonymous so you know there is another party to the transaction but you do not know who it is.  Or, I could tell you I want to buy your property but I am actually doing it on behalf of another person but you do not know I am doing that and possibly then I assign the contract to that other party at closing.  

I have been a part of a partially disclosed principal one time in my career. This usually only occurs with parties that are well known and don't want their identity to interfere with the negotiations.  It is messy and potentially a risk & liability and for just the average agent does not come up very often and if it does it is really important to have your broker and a contract attorney involved or refer it to someone else who knows how to do it. -Kasey

UPDATE: Debe Maxwell, CRS makes a very good point.  State practices and laws vary so it is exceedingly important that you are learning your own state rules, regulations and laws.

I still don't know how you are taking a pre-license course online.  Do states actually allow that???

I am really confused lately I keep seeing very old questions sometimes anyone know why? Hope you found your answer but I doubt anyone will see my answer since the question is so old

I enjoy these questions, good luck with the studies.

Life gets easier when you learn to learn on your own.

What Joe said, he nailed it.

i don't have one

I doubt the laws in my state are the same as other states ... so we need to be careful as to not misguide you.

best of luck to you

Sorry, I don't have any.

Corey Christiansen - I have not worked with either partially disclosed or fully undisclosed principal - yet.

Please take time to do your own research..it's amazing how much you will learn.

This is way too complicated even for a 37 year veteran in the business.  Don't fret this kind of stuff.

It is time for you to read your materials and the laws and regulations in your state.

  We don't do that in Florida, so I can't help you.

I wouldn't ask that question to an audience of mostly non-Utah agents - state laws may vary.  Your instructor should be giving you these answers instead of throwing you to the wolves!

You are better off doing your own research on this. And perhaps discussing with your teacher. I have no examples of either for you

Joe Pryor gets my vote on this one!

I have no such examples... why don't you ask your instructor for clarification?
