In Colorado, the situation you described would probably end up with the listing broker changing his "status" to that of "transaction broker", where they handle the details of the transaction and provide all the needed information and disclosures but are not supposed to advocate for one party or the other.

if you have party A make a P and S contract on the property you deliver the disclosures to that party.. but then Party A flips it to party B and the agent does not know and now you need to get disclosures to this person..

Congrats to both of these parties for being the first with Barnard Enterprises, Inc.

In order to prove that it's surveys, city codes, plus one party already "lawyered" up, so it's going to cost money and waste time.  

It's been around for a while and I don't think there are any other interested parties. 

That deed would not be enforceable until the other party has passed away, or declared legally a ward of the state.

They have a fiduciary responsibility and are basically 3rd parties.

The lien priority on this one looks like this:Lien A (foreclosing party)Lien B (second in priority, third in time)Lien C (third in priority, second in time)C signed a subordination agreement with B at the time of B's DOT, so B is third in time but second in priority.

Third Party Investor -Bring in a third party investor and joint venture with them.

I'm late to the party but here's my two cents.
