Thank you, ForeverDad! I was hoping for you might chime in

Her son was separated from his wife at the time of his death. When the wife left him, she took the boys with her to an apartment. I *believe* her son stayed in the marital property where my friend occupied the basement/mother-in-law suite (and had for at least some of the marriage). As such, she had been very much involved in their lives. I would imagine on a daily basis for some of the time (don't know how long they were all in the marital property together). She has not seen them since the funeral. She said she's been sending birthday, Valentine's Day, Christmas cards, etc.
FYI, the wife evicted her from the mother-in-law suite immediately after his death.
I can only imagine how much these grandsons need my friend, their grandmother, in their life.
Thanks for the great input... .especially the part about the limited window of opportunity. I will pass it on immediately.
Anyone else had any experience actually pursuing this?
Love the input. Many thanks!
