My dad inherit many acres of land in Jalisco,MX from his grandpa when he was a teen. When he came to USA, he kept half of the land and the other part he past to my grandpa to sell to pay for any medical fees and take care of the family. My grandpa didn't have much land to divide to all eleven kids.The land my dad past to his dad was to be divided between them and what ever money was left from sells was to be given back to my dad. My grandpa past on years ago but now that my grandma past away theres is family feud between the agreedment my dad and grandpa once made between his land his grandpa gave him. The problem is my grandpa trusted so much one of my aunt and put her in charge to make all the arrangement to divide all land between them. Since my grandpa didn't put the conditions in his will and only my aunt's name she's taking advatage of only her name being on the will and sayin everthing my grandpa owned is all hers. Before my grandma past away my dad have mention to me about the agreedment he made with my grandpa giving piece of land to each brother and sister. Everybody knew the conditions and that's why they were all in shock when my aunt said everything is hers. What can be done in this situation.
