There is not one fiduciary duty that is more important than the other.  They are all "legal responsibilities" we must perform when working with a client.

Confidentiality

Obedience to the Laws of our State

Accountability

Loyaly

Disclosure

 We have answer this question several time already. 

Undivided LOYALTY - because without it you really aren't REPRESENTED

they are ALL equally important.... because it's the law....

Still loving this question, thanks for asking.

Think about it

They all  carry equal weight!

The first is not to be anonymous! They are all equally important. This question has been asked/answered dozens of times in the Rain. Why don't you research what's been answered in the past, digest the material, and write your own post about what you think the most important fiduciary duty is and why... you'll learn so much more that way.

If you really have to ask this question you need more training.

All of them are equally important. Memorize and practice. 

All of them are equally important.

They are all important...

I believe you have received your answer more than once. They are all equally important, and none of them should be ignored.

Please see my previous responses to this question.

why?

All the duties are equally important and you cannot pick and choose which ones you want to offer.

Like blood and oxygen are to life... all the fiduciary duties are important to staying legal in real estate.

Revealing your true identity.

They are all equally important. Violate one and you violate them all.

They are all equally important!

I believe they are all important

All important

They are all important if you want to avoid problems.

They are equally important because it's the law and it's the right thing to do.  

They are all important! 

Each one of them is most important.

All are important.

Start with honesty and it leads to all others

They are all FIDUCIARY! by definition they are ALL the HIGHEST standard of care. "A fiduciary duty is the highest standard of care. The person who has a fiduciary duty is called the fiduciary, and the person to whom he owes the duty, is typically referred to as the principal or the beneficiary. If an individual breaches the fiduciary duties, he or she would need to account for the ill-gotten profit."

Honesty. Everything else depends on it.

Using your name
