dealing with a death of an estranged family member

I just found out that DH's brother died a month ago. They have been estranged for several years, its a long story of why. He is having a rough time of it and I dont know what to say or do.

Just be there when he needs you.
My mom's stepfather died years ago. When she became an adult and started her own family, she had written him off. Perfectly content not to interact with him again.
When he died, I didn't feel sad or upset. He was the only grandfather I'd ever known, but I felt nothing. She told me that I didn't have to go to the services, because she wasn't, but if I were to go to go for my Aunt. She had a better relationship with him than my mom did.
I didn't go. And my mom flipped a nut on me for it. I told her that I was given the option, by her, not to go and I chose not to.
Sorry, tangent really. But just be there when he needs you. Maybe make some suggestions to do things he enjoys, or make his favorite meal. Just to let him know that you care and you're there for him.

Thank you love!
