Grutz conveys "to Nellie, Anna, and Katherine as joint tenants with right of survivorship."
Case One
Nellie conveys her interest in Blackacre to Pete Ricketts.
What result?
--Ricketts holds a 1/3 interest as a tenant in common with Anna and Katherine.
--Anna and Katherine continue to hold the remaining 2/3 interest as joint tenants with right of survivorship. See casebook p. 391.
So, if Anna dies first, Katherine owns a 2/3 interest as the surviving joint tenant. Ricketts has a 1/3 interest as a tenant in common with Katherine.
Do y'all understand this?
Case Two
Now, instead of conveying her interest to a third party (Ricketts), Nellie conveys her interest to Anna, one of the original joint tenants.
Now what result? When Anna dies and devises her interest in the property to her 4 nieces [she loves her nieces to pieces], do they get 1/3 or 2/3?
Is it possible to argue that the entire joint tenancy has been severed? On what theory?
