Hi,
I'm in a very similar situation.
TDUI was granted by BVA and other accompanying claims were granted in so far as service-connected, while others were basically denied or remanded.
What my most excellcent Vet attorney's case manager told me
[ on here even, they agree this team is one of the best]
Is that it does not go back to RO, since TDIU was granted. ( that part of claim and others granted). It goes to a different office, where my legal team now submits a date, with evidence, the TDUI should have been paid from.
It's nothing for RO to decide. They have some kind of interim office set up now, when such is granted, to just get correct date concerning back pay.
They told me should be around 4 months or so till actual $ is sent.
My Marine husband died 2012 with open claims.
And the biggest hug to Berta, cuz before I read her writings here, I had no idea I could, as his widow, do a thing to keep fighting, which he told me to do, on his deathbed...for his sons.
He died at 90% which basically meant nothing for me or his sons. Even though I knew the seriousness of it all how VA kept him at 90%
I did NOT know I could substitute myself in claims till after his death and just heart-broken, I was reading other stories till I read Berta.
You will never know how much you helped me and our sons, Berta for I have no words to tell you.
He told me to fight it...the 90 percent and even he didn't know how.
I am sure he is smiling from heaven, with rays of light on Berta. And thanking her.
