My mother passed 1 year ago and my sister is the trustee of her trust.
There are 3 beneficiaries ; my sister (trustee) and my brother and I.
One of the assets was my mothers house whom my sister is selling to her son (my nephew).
My brother and I agreed to sell it to my nephew at fair market price 1 year ago and my nephew has had problems getting the financing and the asset is now worth considerably more (+ $100K) and when I mentioned it to her she claims we agreed to the price 1 year ago.
The average time real estate is on the market in Colorado is approx 21 days and this asset has still not been sold to my nephew.
How do my brother and I as beneficiaries prevent her from selling the asset substantially below the fair market value to her son??
