Mont. Code § 76-4-113
The developer or owner of an approved subdivision shall provide each purchaser of property within the subdivision with a copy of the plat or certificate of survey and the certificate of subdivision approval specifying the approved type and locations of water supply, storm water drainage, and sewage disposal facilities and information regarding connection to municipal, county water and/or sewer district, or regional authority facilities provided for under 76-4-130. Each subsequent seller of property within the subdivision shall include within the instruments of transfer a reference to the conditions of the certificate of subdivision approval. The seller of any lot recorded with the exemption in 76-4-125(1)(c) shall include within the instruments of transfer a reference to that exclusion and a statement that the lot has not been reviewed or approved under this part. A written verification of notice that is signed by both the seller and the purchaser and is recorded with the county clerk and recorder constitutes conclusive evidence of compliance with this section for that transaction.
