Frequently Asked2
Does temporary unity of ownership extinguish an easement appurtenant?+
Yes. The rule focuses on whether the owner could make the authorized uses by virtue of fee ownership during the period of unity. Temporary unity still extinguishes the easement to that extent, and the easement does not revive upon later severance without a new grant.
Does partial acquisition of servient land extinguish an easement appurtenant?+
No. Extinguishment occurs only to the extent the owner can make all prior authorized uses by virtue of the acquired estate. When the purchase covers only part of the servient land needed for the easement uses, the easement remains in place for the uncovered portion.

Randall formed Fair Stay as a corporation with minimal capital and deposited all room-rental revenue into his personal account. He issued no stock, held no meetings, and kept no records. When Fair Stay could not pay Premier Hotels after an economic downturn, Premier sued Randall individually. The unity of interest shown by commingling and disregard of formalities permits the court to pierce the veil and hold Randall personally liable.
Frequently Asked2

When these factors demonstrate that the corporation and shareholder have no separate personalities, the first prong of the veil-piercing test is satisfied.

Yes. The second prong requires only that adherence to the corporate fiction would sanction fraud or promote injustice. Courts have pierced the veil when an undercapitalized shell used to avoid personal liability would leave a creditor without remedy even absent deliberate deceit.
