You can do it through a simple online process.
Have you filed your claim online?
No, I have done so through a written letter.
Unfortunately, no relevant information is found.
What if it has been more than a year since I got married?
We may not refund the date of the marriage. Instead, we may reimburse you only for the date we receive your claim for additional disability for the dependent.
You've got it. Another query about  DBQs. Is it possible to find out if I've completed all of the necessary forms?
Yes you can see if you need to complete any additional forms online.
Do I file federal or state records or both?
Documents which you upload to support your disability claim should be both Federal and state records including your military medical and personnel records.
If this doesn't work out can I upload more evidence?
