The Pennsylvania L.B.F. 8012-1 Disclosure Form is a legal document that is used to disclose certain information to a potential buyer or seller of a property in the state of Pennsylvania. The disclosure form is required by law and must be completed prior to the closing of a real estate transaction. The form is designed to provide disclosure of any known material defects in the property and any other pertinent information related to the sale or transfer of the property. The form also requires the seller to provide certain warranties and guarantees of the condition of the property. There are two types of Pennsylvania L.B.F. 8012-1 Disclosure Forms: the Seller's Disclosure Form and the Buyer's Disclosure Form. The Seller's Disclosure Form is completed by the seller and provides information about the condition of the property, including any known material defects. The Buyer's Disclosure Form is completed by the buyer and provides information about the condition of the property at the time of purchase. Both forms must be signed and dated by both the seller and the buyer prior to the closing of the transaction.
