Connecticut breach of offer to purchase

[franklinreed]

What is the name of your state? Connecticut

We were excited about purcahsing a new home. Went as far as getting an accepted signed-offer to purchase. Both parties agreed to the terms. Later that evening the Seller through the Agent relayed a counter offer to us that was slightly higher than the original. We found this odd because we had already signed the agreement and were moving to contract. However we were willing to match the new offer anyway. Then a few hours later we were informed that the seller was going with the other offer. Do I have any legal rights since both parties signed an offer earlier that day? It's very frustrating, if there are no legal rights, the offer process is a complete waste of time. The offer must be somewhat binding?
Plus we suspect the realtor disclosed our signed/accepted offer to others to create a bidding war.

Thanks for your help

When the seller signs the buyer's offer, that constitutes the seller's acceptance, and the offer to purchase ripens into a sales contract. If the offer is only signed by you, the buyer, there is no contract. An offer can be made and never acted on (signed) by the seller. Do you have a copy of your offer signed by both yourself and the seller? If not, then you do not have an acceptance by the seller.
