Ma'am after waiting so long, you have an uphill battle. But it is not insurmountable.
But first some background information...
If he was retired, on his death his pension ends. That is true for every retired veteran. The pension ends with the death of the veteran.
Now, the military has an insurance program, called SBP, that allows a retired veteran to purchase financial protection for their dependent. This insurance program must be elected and paid for...it is deducted from their retired pay.
If he had sbp, if you file this formhttp://www.dtic.mil/whs/directives/infomgt/forms/eforms/dd2656-7.pdf
And mail it to DFAS
DFAS - U.S. Military Annuitant Pay
P.O. Box 7131
Fax: (NNN) NNN-NNNN
They can process the claim and start to pay you the insurance.
But this assumes he had SBP.
Since this was almost 10 years back, it may be you do not have records....but if you do, take a look at his most recent retired pay stub...if it shows a deduction for SBP? That means he had it (and you rate it). If it is not listed, then it means he did not elect this insurance plan (so you would not be able to collect)
You can contact DFAS yourself and ask them to check if he had SBP. You can call them at
I would call them and ask...see if he had SBP. Or you can file the form I linked to you and apply for it straight away
Again, they can not pay you unless he had elected and paid for the insurance...but if he did? You rate an annuity and you need to apply to get it
Please let me know if you have more questions...happy to assist if I can
