NC for this post. When we bought our house from our builder/developer we were ask to sign several forms as part of the contract which they completed and then asked us to sign. These forms related to various details of the purchase. The builder kept the originals but provided us with a copies when we asked at the time. We have found out that they changed at least one of the forms after we signed it. It is very clear that the form has been changed and it now has different information on it to the copy we signed and were given (obviously). AIBU in thinking that this is fraud?
