That's why when I sold my NB house I refused to sign a seller's disclosure form. AFAIK the house was in great shape, but there was no upside to signing that declaration, only downside in that I am assuming liability for things I may not understand, such as the wiring or plumbing, since I have no idea of its specification or condition, only that it worked fine for me. The buyer tried to push for the agreement but I was in no rush to sell. Instead I told them to send in their home inspector to check whatever they wanted to see, so that the inspector is liable, not me.
