Which form is required for the course of development of an individual unemployability claim?

The form required for the development of an individual unemployability claim is the 21-8940. This form, also known as the Veteran's Application for Increased Compensation Based on Unemployability, is specifically designed for veterans who believe that their service-connected disabilities prevent them from maintaining substantial gainful employment. By using this form, veterans can provide necessary information about their work history, education, and the impact of their disabilities on their ability to work, which is essential for the VA to make a determination regarding their entitlement to increased benefits based on unemployability.

Other forms listed serve different purposes within the VA system. For example, the 21-4502 is used for applications related to veterans’ benefits for dependents, while the 21-2680 is a form for demonstrating the need for aid and attendance or housebound benefits. The 21P-534 is utilized for applying for death benefits and does not pertain directly to individual unemployability claims. Therefore, the 21-8940 is the correct choice for veterans pursuing a claim for individual unemployability based on their service-connected conditions.
