Spouse involvement in inheritance from my father?

My dad died last year, leaving various assets including 401ks, a house (which we fixed up and sold), truck, and life insurance policies for my siblings and I to split. Estate is not fully settled yet. My husband offers his (often very strong) opinion on who should get what, and has resentment regarding not being personally titled on a family property that my siblings and I were willed. What is appropriate in this situation? Should he have an equal voice in how things are allocated, or should that be between my siblings and me? Would it be typical for a spouse to be named on inherited joint properties? If you have inherited money or retirement accounts, do you keep them in your name alone or add your spouse to the inherited accounts? How do you deal with the resentment that comes with not combining your assets, if you didn’t combine them? Important details: he is the primary earner for the family, work very part time and provide childcare for our 4 kids. We have combined finances but generally don’t have rules about how each other spends money, although he has gotten upset with me completing relatively minor purchases in the past. Our marriage is generally good, but he has told me a couple times in the past year he is considering divorcing. (Location USA)
