Fractured Inheritance: Quantifying The Economic Impact Of Heir’S Property On Arkansas Farmers, Makenzie Mcjunkins
Fractured Inheritance: Quantifying The Economic Impact Of Heir’S Property On Arkansas Farmers, Makenzie Mcjunkins
Graduate Theses and Dissertations
Heir’s property arises when the original owner still holds the title despite their passing, and ownership is distributed among their heirs. This was driven by barriers to retaining land ownership and access to legal support in predominantly African American populations in the early 20th century. This approach allowed land to remain in the original owner's name while granting continued ownership to future generations without formal paperwork. Additionally, allowing limited land access, land management, and disparities in capital access compared to property with direct ownership rights. This analysis examines how modern heir’s property impacts agricultural returns. This study develops a conceptual …
