Which form of co-ownership allows for unequal shares and has no right of survivorship?

Tenancy in Common is the correct answer because it allows multiple individuals to own property together, but with the flexibility of holding unequal shares. This means that one owner can possess a larger or smaller portion of the property compared to the others based on the ownership agreement or purchase arrangements. Importantly, Tenancy in Common does not include the right of survivorship, which means that if one co-owner passes away, their share does not automatically transfer to the other co-owners but is instead passed on according to their will or estate plan. This characteristic distinguishes it from other forms of co-ownership like Joint Tenancy, where the right of survivorship is a fundamental feature. In contrast, Entireties Ownership typically applies to married couples and inherently includes rights that differ from individual ownership structures. A Partnership Agreement, while it may involve co-ownership in a business context, does not directly pertain to real property ownership in the manner described in the question.
