When X and Y co-own a property and X dies, who inherits X's share?

In a co-ownership situation between X and Y, the manner in which they own the property determines what happens to X's share upon X's death. If X and Y own the property as joint tenants with rights of survivorship, Y automatically inherits X's share. This feature of joint tenancy ensures that when one co-owner passes away, their interest in the property transfers directly to the surviving co-owner without the need for probate or other legal proceedings.

This automatic transfer is a key characteristic of joint tenancy, distinguishing it from other forms of co-ownership, such as tenancy in common, where a deceased owner's share would be passed on to their estate and then to their heirs rather than directly to the other owner. The fact that Y inherits the property share without any necessary actions like selling or dividing it reflects the fundamental principle of joint tenancy that aims to provide clarity and continuity in ownership.

Therefore, in this situation, the correct answer highlights the nature of joint tenancy and its impact on the transfer of property upon the death of one of the owners. This understanding is crucial for anyone involved in real estate transactions or ownership arrangements.
