Lease by One Joint Tenant
Johnson and Boswell held Blackacre as joint tenants. Johnson leased his interest to a third party for five years. The court examined whether the lease destroyed the unities of interest and possession and concluded that the joint tenancy remained intact because the lease was valid only during Johnson’s life.

Commingled Hotel Revenues
Lena and her siblings ran Harborview Inn through Harborview, Inc. They never issued stock, kept no minutes, and deposited all revenues into personal accounts to pay home mortgages. After a guest was injured and obtained a judgment, Lena moved every asset into a new LLC. The court found the required unity of interest and ownership between the corporation and its owners and pierced the veil.
Undercapitalized Shell Transfer
The Garcia family formed Sunrise Harbor, Inc. to own their hotel. They issued no stock, kept no records, and paid personal car loans from the corporate account. After a balcony collapse, they shifted every asset to a new LLC. The court held that unity of interest and ownership existed and allowed the injured guest to reach the owners personally.

It could be argued that a lease destroys the unities of interest and possession because the leasing joint tenant transfers to the lessee his present possessory interest and retains a mere reversion. (See Alexander v. Boyer (1969) 253 Md. 511 [253 A.2d 359, 365].)…
