I am preparing the form 21-534 to apply for Aid and Assistance benefits for my mother. Just today I found the information to submit an informal application, VA Form 21-4138, to get the application on record while I am compiling the information for the formal application. Other than the reference to 38 CFR 3.155 Informal Claims. and the statement about appointing a fiducuary as soon as possible, is there any other information that I need to provide in this statement section of the form? Thank you!
