Land dispute over sale.

Hey guys,

Could you please help me out with the best legal advice on a dispute of property, as it is under three people ownership. The property which is just sitting idle but when it comes to negotiation for selling it one person is creating a fuss for not selling neither renting off, however among the three owners two are agreed in selling it away what legal ways can be used to this matter. And would legal ways be of any use?

Your advice would be truly appreciated.

Cheers
