How to buy out a sibling on shared property?

Question Details:

Approximately 16 years ago I inherited a house with my 3 siblings. At the time my brother lived there alone so I moved in and I bought out 1 the share of one my sisters. I now own 1/2 the house and my brother and other sister own 1/4 each. My brother refuses to work and pay bills, he has liens on the house from creditors, and has even refused to pay house taxes. In the last 2 years I have had to pay his share so as not to loose the house. Can I force him out as I own the majority and how are his liens going to affect me and the house? Important Notice
