Possible purchase questions

[Jared Christensen]

Ok here is the long story and any feedback that can help would be most appreciated. I was approached a couple weeks ago from a partner on 4 8 unit buildings. Long story short there use to be 2 owners and one passed away so now it is one guy owns 1/2 and the other 1/2 is owned by 3 (the deceased’s kids) well anyways it was never advertised for sale very well but they did get an offer to sell them for $775,000. The 1/2 owner signed a purchase agreement with the buyer but one of the children called me up and said hey do you want to buy these would you offer $800,000. I said I sure would. Now I am fighting with the 1/2 owners lawyer who is also his real estate agent to give me any information on the buildings. Can he sell the buildings without the other party signatures being 1/2 owner? Or will they need all 4?
