Equitable Conversion and Separate Deposits
Pulse Media contracts to purchase two adjoining parcels containing distinct geological formations. After the contract forms but before closing, a fire destroys surface improvements on one parcel. Under equitable conversion the buyer bears the risk of loss on that parcel while the property concept requires Pulse Media to treat each formation as a separate tax property for depletion purposes once title passes.
Due Process Limits on Property Units
Premier Manufacturing holds multiple mineral interests across state lines. When a state seeks to tax one interest as part of a larger unit, the company invokes the Fifth Amendment to argue that each geological deposit must remain a distinct property under the property concept, preventing aggregation that would deprive it of property without due process.
Paragon Construction receives advance payments from an oil and gas client for work on two separate leases. The firm must place those funds in a client trust account under Rule 1.15 while simultaneously tracking each lease as an independent property under the property concept for the client's future depletion calculations.
Landlord Obligation and Separate Tracts
Prime Logistics leases two noncontiguous parcels for drilling operations. When one parcel becomes unsuitable for residential use by workers, the tenant may terminate only that lease under the Restatement while the property concept continues to require the company to treat each geological deposit on the remaining parcel as a separate tax property.
Nuisance Harm to Distinct Deposits
Piper Patel operates wells on two separate geological formations. A neighboring activity causes significant harm to only one formation. Liability for nuisance arises solely with respect to the affected property because the property concept treats each deposit as an independent unit for measuring harm and allocating tax consequences.
Minimum Contacts and Property Units
Pierre Poulin owns mineral interests in two states. A plaintiff attempts to assert jurisdiction in one state based solely on the presence of the second interest. The court rejects the claim because the property concept defines each interest as a separate property, and unrelated property in the forum does not create minimum contacts.
Common questions
Frequently Asked
2
How does the property concept affect depletion calculations?+
Each separate legal interest in a distinct geological deposit on a separate tract constitutes an independent property. A taxpayer must therefore compute depletion separately for each such unit rather than aggregating interests across tracts or formations.
Does the property concept apply only to oil and gas or to other minerals?+
The concept is defined for oil and gas tax purposes but rests on the same principle that each distinct legal interest in a geological deposit on a separate tract forms its own property unit.
