My husband and I are separated, but not legally. While we were married he was in the process of a lawsuit regarding an injury. Am I entitled to funds?

In the apartment complex where we lived, he was walking on the sidewalk at night with my daughter, and he tripped over a rusty rebar that was sticking out of the ground bent towards the sidewalk. His shoulder dislocated and fell hard on his knee. He’s a Professional Trumpet Player all his life, which he claimed every year on his taxes. He is now Disabled collecting Social Security, due to the accident. I helped him the first year, taking him to therapy and an Orthopedic doctor, as well as obtaining information for his Attorney. It happened in August 2018, and the next court date is set for Feb. 28th. for hopefully, the settlement. Also, since this case took almost 4 years, his Attorney is asking for 40%. This took a toll on our marriage, which we were married for 29 years at the time of the accident. We’ve been separated since Sept. 2019. So my question is again, am I entitled to a percentage of the lawsuit money? Btw, he hasn’t given me any child support money.
