My Ex-husband Died Intestate, What Should My Adult Children Do?

Hi all. A bit of background. My (45F) deadbeat ex-husband (50M) and I divorced in 2018 after he was convicted of family abuse. (Long history of domestic violence.) He left the state and due to protective and custody orders has not had a relationship with any of us since, including our daughters (20 and 25.)

Two weeks ago he died in an accident and did not have a will. His parents made no attempt to contact my girls until the funeral home said they needed their written permission to cremate him because the girls are his next of kin.

Since he was working (something he never did during our 18 year marriage, I was the sole breadwinner) at the time of his death and he lived (and ironically died) in his parent's basement, I imagine he left some money behind.

What do my adult children need to do to ensure whatever he had goes to them? He never did a financial thing for them while he was alive, it would be nice if they got something out of him in death. EDIT: The girls and I are long-time Virginia USA residents and my ex-husband moved back to Pennsylvania USA in 2018 and lived there until his death.
