Do I need an attorney for a Partition Action? If yes, what type?

My brother and I inherited my grandmother's house when she passed in 2008. He has 60% and I have 40% ownership. We live in Indiana and I live in California. He lives in the same area in Indiana as the home. I have wanted to sell the home since we inherited it. He declined due to his emotional attachment. I have brought up the option to buy me out over the years, but the last time I asked was in 2012--which he threatened me so I stopped inquiring. I recently found out he's been renting the property for 2-years without my knowledge, input, or consent. I'm not comfortable with this and I'm concerned about the liability aspect. I have more to lose in the event of a lawsuit. I've asked him to purchase my 40% for current market value. At this time, I'm not concerned about the rent he has collected over the past 2-years. He's been ignoring my requests and will not take my calls. It's not my preference, but I believe I may need to file a Partition Action. What type of attorney do I need?
