The pipeline must be assessed by its concrete effect on the purchase price. A line below an undeveloped edge of the property has a different significance from a route beneath a planned house or access road. Location, protection strip, permitted use, access and the cost of adjustments are decisive.
The contract should identify the pipeline rights and supplied documents precisely. This includes the operator, pipeline, parcel numbers, plan version, protection strip, known consents and open coordination. A general acceptance of the property as inspected does not answer these questions.
For open issues, the parties can link maturity of the purchase price to particular evidence, operator confirmation or a binding clarification of the intended use. A retention, assurance, cost allocation or rule for a different route may also be considered. The appropriate solution depends on the importance of the pipeline for the specific purchase object.
