I could be wrong but your question puzzles me. If she's your friends's spouse, she shouldn't be receiving DIC. If you misspoke and she's your late friend's widow, she will probably just need her DIC award letter. I believe a widow loses DIC, when she remarries, except after a certain age, when she's allowed to continue to collect it, in spite of the remarriage.
It would be crazy for a widow to remarry, due to the loss of benefits. jmo
