Conn. Gen. Stat. § 47-14c: Conveyance by less than all joint tenants.

Except as otherwise provided in sections 47-14a to 47-14k, inclusive, a conveyance of any interest or interests in any joint tenancy by less than all of the joint tenants to a person or persons other than one of the remaining joint tenants severs the joint tenancy as to the interest or interests so conveyed and the grantee or grantees thereof shall hold the interest or interests as tenant or tenants in common with the remaining joint tenant or tenants. When there is more than one such remaining joint tenant, the conveyance does not alter the character of the tenancy or its incidents among the remaining joint tenants.
