I'm kinda surprised at how vague all these postings are, so let's go back to the books.
*No thanks for the homeopath analogy; people who work in real estate are LICENSED, state-by-state. In addition, we're members of a national trade group, the National Association of Realtors. Oversight is conducted by local boards; if you're in NYC (and it sounds like you are) start with the Real Estate Board of New York: www.rebny.com.
Second, it is not guesswork what your agent owes you. A buyer's agent owes you four SPECIFIC things: the fiduciary duties of care, confidentiality, loyalty and disclosure.
* CARE means the representative is not supposed to be negligent -- for example, when you hand the rep a check, the check is supposed to go into an escrow acccount, not into a swiss bank account.
* CONFIDENTIALITY means if you tell the agent you're looking for a $500K apartment, but you're going through a divorce and you could go up to $700K, and the agent is negotiating to buy you a $600K apartment, they're not supposed to tell the seller that you'd be "in a distressed situation and happy to pay $700K."
* LOYALTY means that if you're working with the rep and you two see a $1M place on Perry Street for $50K, the agent isn't supposed to buy that apartment for himself or herself. The agent should put your interest first.
* DISCLOSURE means the agent has to tell you everything material he or she knows about the transaction: Does the seller know of lead paint hazards? Are there condos going up next door that will block your view?
Whether there being lousy communication about your agent's title is a violation of disclosure really depends on other aspects of the relationship between you and your agent -- do you feel there's been a pattern of untruth, somehow? If so, call REBNY.
If not, ask yourself why, just as you're entering contract negotiations, you would want to ditch your trained negotiatior -- who many posters here have pointed out will be paid from the seller's pocket, not yours.
Since this is your first purchase, my guess would be some larger underlying issues are at play. (Buying a first home is pretty freaky, but you'll survive it, I promise!) Still, crap like this is the reason I don't work in NYC.
