Two or more persons named as owners in a document of title, transferees in an instrument of transfer or buyers in a bill of sale are tenants in common, except as otherwise provided in s. 700.19 or ch. 766.
Wis. Stat. § 700.18
A warranty deed to 2 grantees as "single persons" did not express an intent to classify the property as something other than survivorship marital property when the grantees subsequently married. The use of the phrase "single persons" simply described a fact: that at the time they purchased the vacant lot, the grantees were not married. "Single persons" does not represent a classification of property ownership of any kind, to wit, tenancy in common, joint tenancy, marital property, or any other recognized classification. Droukas v.
