Realtor by laws can your realtor disclose other bids?

[Brian Bertschi]

Are there any laws for a realtor to not be able to disclose a bid on a property? My grandmother recently put in a cash offer for a condo. It was a few thousand dollars less than asking price. Her realtor said there are a few offers on the condo. When my grandmother asked what the offers were the realtor said she couldn’t say but my grandmother needed to make a strong offer. Any insight would help thanks.
