Veterans who never reported an injury, mental health condition, or event (such as military sexual trauma or a toxic exposure) during their active service can still qualify for VA benefits and disability compensation. Delaying a claim or initially not calling it in does not permanently disqualify you.You can establish a service connection later if you gather the right evidence. To build and win a claim after the fact, focus on the following steps:Gather Medical Evidence: Obtain current medical diagnoses for your conditions and show they connect to your active-duty service, even if years have passed.Write Personal Statements (Buddy Letters): Use a VA Form 21-4138 to provide a personal statement describing the in-service event or injury, when it started, and how it impacts your life now. Lay statements from friends, family, or fellow servicemembers can also help corroborate your story.Look for Corroborating Evidence: Even if it wasn't in your official medical record, look for unit records, deployment logs, hazard pay records, or buddy statements verifying your exposure or the event.File an Intent to File: Submit a VA Form 21-0966 to officially start the timeline and preserve potential back pay while you gather your evidence
