We sold our house 3 weeks ago at Auction. The deposit, unknown to us, was not paid. We were informed a few days later the buyer was pulling out despite a signed contract. We served a default notice 14 days ago and the buyer has disappeared.Did our agent break our contract by not getting a deposit cheque at auction? Should we hunt the buyer down? Is it worth the cost and stress of suing for the deposit? Our conveyancer has said we could still owe the agent commission as they did sell it (even though not finalized) We dont know what to do
