A more thorough explanation:

An undivided interest refers to a situation where two or more people own a property together under the same title. This means that each owner has an equal right to the entire property, and no one owner has exclusive rights to any specific part of the property.

For example, if four people own a 10-acre piece of land under an undivided interest, each owner would have a 25% undivided interest in the entire 10 acres. This means that each owner has an equal right to use the entire 10 acres, and no one owner can claim exclusive use of any part of the land.

Undivided interest is commonly used in real estate, where multiple owners may jointly own a property. It is important to understand the concept of undivided interest when buying or selling property with multiple owners, as it affects the rights and responsibilities of each owner.
