Any private property, usually. Personal property is often exempt but there are different conceptions of where the line is. The most compelling to me is the concept of usufruct, wherein ownership is conferred by use. So anything you are personally using would belong to you and could be kept until you were done with it. But you could not impose a property claim on anything you are not using, because to do so would be to unjustly deny its use by someone else. Land is certainly a common example, but buildings, goods, anything could be viewed through this lens.
