Final answer:
The ownership interest of a co-owner who passes away would usually pass to the remaining co-owners through the right of survivorship.
Step-by-step explanation:
When a co-owner passes away, the ownership interest usually passes to the remaining co-owners. This is known as the right of survivorship. In the absence of a will or trust, the deceased co-owner's share will be distributed among the surviving co-owners according to the governing laws of the state. For example, if there are two co-owners and one passes away, the surviving co-owner would typically become the sole owner of the property.
