Sorry to tell you that Ct's adverse possession statute would certainly apply. What you have not made clear is who has been using that 32 ft into what you believe to be your property? If you have been mowing, gardening etc. for these past 40 plus years, then the statute applies to your benefit, despite whose survey erred. But if the subdivision and or the new property owners have been using that land, then so much time has passed without you objecting that they could claim under the statute. You need a lawyer, before you waste money on a fence.
