Unpaid Taxes and Owner Passed Away

[Lisa Jones]

Hello,

I want to make sure I have no other options. There's a vacant lot that has had taxes unpaid for at least 7 years. Value wise I'm not concerned at this point. The problem is that the owner passed away years ago. She had multiple kids and her kids have since had kids. I spoke to one of owner's grandkid which was originally helping pay the taxes and maintaining the lot. She mentioned she does not want to deal with the family because of past issues and no one is willing to sit and discuss the sale of the land. Something to that effect. 

Is the only solution to go to probate? Which if I'm not mistaken could cost thousands and take a lot of time. Or maybe adverse possession, but then I run the risk of someone coming back to claim the land?

Other than that, the property will just continue to go to the tax certificate sale every year, until someone actually sends it to auction, correct? I don't think any of the investor really care for the land bc it's small and so much is owed in back taxes. But I have family members in the area and would like to utilize that land for something. 

Please help.
