How to find out if my mother had a will and if I am a beneficiary

My mother past Christmas of 2018, I'm sure she had a will, however the family's not on good terms. I know she had some property and my sister and my self names were on it. Aslo my father passed Oct 30th around 10 years ago it took almost 5 yrs to agree on finals of it, however it was not completed. There was 10,000.00 held in escrow incase of past taxes. This was in judge bakers court 2 times. He told the lawyers to get an accountant to get a total figure and resolve this Issue, however my attorney past about 4 years ago and then the other attorney I got after that had a stroke. I've yet to see anything from this money.
