What is the defining characteristic of an estate in severalty?

An estate in severalty is defined by the fact that it is owned solely by one individual. This form of ownership means that the owner has complete control over the property and full rights to manage, use, and dispose of it without needing consent from any co-owners. This characteristic distinguishes it from other forms of ownership, such as joint tenancy or tenancy in common, where multiple individuals hold an interest in the property.

In contrast to scenarios that involve multiple owners or partnerships, an estate in severalty provides the owner with the autonomy to make decisions regarding the property independently. There are no obligations to share rights or responsibilities with others, which can simplify management and decision-making regarding the asset. The key feature of singular ownership encapsulates the essence of an estate in severalty and underscores its practicality in matters of real estate.
