 What does it mean to ask if existence is a property? A full answer to this question requires a general theory of properties, which is well beyond the scope of this article. But we can briefly sketch the landscape to set up our discussion of existence. (See the entries on  properties  and  substance  for deeper discussion.) Properties contrast with individuals. This distinction can be explicated using the instantiation relation. My cat instantiates the property of being hungry, as that is a way he is. As my cat is himself an individual, he is not instantiated by anything. So, while properties also instantiate—the property of being red, for example, has the property of being a color—only properties are instantiated; individuals only instantiate. Our first question is whether existence is instantiated and, if so, whether it is instantiated by individuals like Obama, my chair, and the fig tree in my backyard. Do individuals, in addition to ordinary properties like being hungry, being human, being comfortable to sit in, and needing more water, instantiate a property expressed by the English verb ‘exists’?
