The VA has a legal obligation to help veterans develop their claims before making a decision. This obligation, known as the duty to assist, requires the VA to take specific steps to gather relevant evidence, provide medical examinations when needed, and notify veterans of what is required to substantiate their claims. When the VA fails to meet these obligations, it can be grounds for overturning an unfavorable decision and getting a new review with proper development.
The duty to assist encompasses several specific requirements. The VA must make reasonable efforts to obtain relevant federal records, including service treatment records, VA medical records, and Social Security Administration records. They must also make reasonable efforts to obtain private medical records that you identify and authorize them to request. When there is insufficient evidence to decide a claim but indication that the disability may be connected to service, the VA must provide a compensation and pension examination. Additionally, the VA must notify you if it cannot obtain records you identified and give you the opportunity to submit them yourself.
Common duty to assist violations include failing to obtain service records or VA treatment records that are clearly relevant to the claim, providing an inadequate compensation exam where the examiner did not review the claims file or failed to address the central medical question, failing to provide an exam at all when the evidence triggers the low threshold for requiring one, and not considering all conditions reasonably raised by the evidence even if the veteran did not specifically name them. An exam can also be inadequate if the examiner based their opinion on an inaccurate factual premise or did not provide a sufficient rationale for their conclusion.
How you raise a duty to assist violation depends on where your claim is in the process. Under the Appeals Modernization Act, if you choose the Higher-Level Review lane, the reviewer can identify a duty to assist error and return the claim for correction. If you are at the Board of Veterans Appeals, the Board can remand the case back to the regional office to correct the error. In a supplemental claim, you can submit the evidence that should have been obtained and argue that the prior decision was based on an incomplete record. The key is to specifically identify what the VA failed to do and explain how it prejudiced the outcome of your claim.
It is important to understand how duty to assist differs from Clear and Unmistakable Error. A DTA failure cannot form the basis of a CUE claim because CUE requires an undebatable error in the decision itself, not a failure in the development process. However, DTA violations can be raised on direct appeal and through supplemental claims, which makes them a more accessible remedy for most veterans. If the VA failed to get your records or gave you a bad exam, DTA is the appropriate framework rather than CUE.
To protect yourself from duty to assist failures, keep copies of every records request you make, document conversations with VA staff about your claim development, and review your claims file periodically to ensure all the evidence you expected to be there is actually present. If you notice missing records or an exam that did not address the right questions, raise the issue promptly rather than waiting for a final decision. Being proactive about identifying development gaps can prevent DTA problems from derailing your claim in the first place.
