Hi JGK. When I started this process I consulted first with a clueless Veteran Service Officer who insisted my parent, the Vet, would not qualify for A&A. He called his contact in Seattle, was put straight, then told us, "Oh, I feel terrible. I turned away three veterans last week". Following this website's advice, I did the complete application and my parent received benefits in four months. Here's a link to an interesting discussion on VSO's and Aid and Attendance:

I can't help with the forms question, but there is a useful search function in the upper right hand corner that might help. Good luck to you. Annie
