Husband and I are building our first home. I paid a builder $1500 to prepare a concept plan and a tender. I did not sign any preliminary agreement and while it may have been mentioned the fee is not refundable, I don’t really remember discussing it. There was some work involved in the concept plan as it was changed 4 times (minor details). The tender was higher than the discussed budget and we decided not to proceed with the builder. The builder retains copyright of the plans so in theory can use them for profit at a later stage. Should I be entitled to any refund of the amount if the terms were not set out clearly to me in writing under Australian Consumer Law?
