Need advice on an Eviction in Indiana

[Jacob Winters]

Hello, I have a tricky situation and wanted to get some feedback. I am in contract to buy a property in Indiana. The owner and her siblings were passed down the property from their dad who passed away. Their distant relatives now occupy the property as the father said they could live there before he passed away. They do not pay rent and there is no lease agreement in place. The siblings want them out as they are not doing their fair share. How do we evict them? I would like to avoid using an attorney as it seems it will cost in total $4000-5000 to use them. Thank you and happy investing!
