yes but it would be a 50/50 kind of thing. if a person is sharing half of the house then they might just be trying to sell it. or something, there are alot of people asking for the owner of this and that house so like the other situation where someone got conned out of their house this is all in trust, i do not care any for houses so i would promote this suggestion with an AT YOUR OWN RISK message.
i would also suggest that the second owner of the house not be able to do certain things like sell the property, or have to console the owner to change the house message.
