What type of estate does Jason have if he is restricted from building on the property left to him by his parents?

In this scenario, Jason holds a fee simple defeasible estate. This type of estate includes specific conditions or limitations placed on the use of the property. The restriction that Jason is not allowed to build on the property indicates that there are certain requirements or prohibitions associated with ownership that could potentially lead to the loss of the estate if those conditions are violated.

A fee simple absolute would grant Jason full ownership with no restrictions, allowing him to use the property as he wishes, while a life estate would mean Jason has rights to the property only for his lifetime and cannot pass it on to heirs, which does not apply here. A leasehold estate refers to a tenant's right to occupy property for a specific period under a lease agreement, which does not relate directly to restrictions on property use after ownership transfer. Therefore, the nature of the limitation on Jason's ability to build strongly aligns with the concept of a fee simple defeasible estate.
