Harry and Sue were the joint registered proprietors of an estate in fee simple of Blackacre as tenants-in-common. Consequently, at common law:

1. Harry and Sue must be tenants-in-common in equal shares
2. Harry and Sue must be tenants-in-common in unequal shares
3. Harry and Sue could be tenants-in-common in either equal or unequal shares, in this example
4. Harry and Sue as tenants-in-common, cannot co-exist as the joint proprietors of an estate in fee simple where the shares are unspecified, and therefore are at law joint tenants with and undivided moiety.
