In a will, what type of interest does a grandson have if he can occupy property while caring for a pet?

The grandson holds a fee interest in the property if the will grants him the right to occupy the property while caring for a pet. This indicates a long-term and potentially indefinite hold on the property, suggesting ownership rights that are characteristic of a fee simple interest.

In this context, a fee simple interest is the most complete form of ownership in real property, permitting the holder to use the property in almost any manner that is lawful and without restrictions other than zoning laws and local ordinances. It represents the highest level of ownership available, allowing for benefits such as the right to occupy, modify, or even sell the property outright, depending on the specific terms laid out in the will.

The grandson's ability to occupy the property while caring for a pet further points to a more personalized and enduring arrangement than what a temporary or limited interest might suggest. Unlike a life estate, which would terminate upon the death of the occupant, or a leasehold interest, which involves renting and does not confer ownership, the fee interest implies a sustained and primary relationship with the property.
