Ownership and Land Use, 15% of the examination
Joint tenancy
Co-ownership in equal shares with right of survivorship, requiring the four unities of time, title, interest and possession.
Right of survivorship operates outside the will entirely, so a joint tenant's interest is extinguished at death rather than passing to their estate. Breaking any one unity, for example by one tenant conveying their share, severs the joint tenancy as to that share and converts it to a tenancy in common.
What this is confused with
The exam rarely asks for a definition. It describes a situation and offers two terms that both sound plausible.
Tenancy in common
No survivorship, shares may be unequal, and the interest passes by will or intestate succession.
Community property with right of survivorship
Available to spouses, and the survivor gets a full step-up in basis on the whole property.
