Please clarify what you mean by "the other three partners sold it at about half price and said there was nothing the trustee could do to stop it."
Do you mean to say that they sold the deceased interest in the partnership? Sold the entire partnership?
What year did this take place in?
Additionally, it's unclear what happened when "one partner took to much from the leasing corporation and he had to pay and give up his share of the partnership?"
It's hard to answer your question without better details.
