I had a verbal contract with my father to run the ranch until his death in exchange for ownership in the event he died....he is 95 now and wants to sell to someone else. I do have a copy of the will that names me as the beneficiary, and evidence to prove i was managing farm for 3years. I would like to get an injunction to stop the sell
Don't jump to conclude that you are prevented from attempting to have the oral agreement enforced just because someone tells you that you can't.
It is true that Idaho as well as the other states have adopted what are known as a "Statute of Frauds" that on their face require that in order to be sustained any agreement designed to create an interest in real property for a longer period than one (1) year needs to be in writing signed by the party sought to be charged. (Here Idaho Code Section9-105(4))
But those statutes have been held not to apply to defeat a claim where there is sufficient other evidence independent of a writing establishing the existence of the verbal agreement. And partial performance of the agreement often stands as compelling evidence of its existence.
The reasoning is that since the very purpose of these statutes is to prevent fraudulent claims when there is other evidence to dispute the claim as being fraudulent there purpose is superfluous.
HOWEVER, there could be a more serious difficulty here. This may not be a question of the statute of frauds at all, but rather one of probate law. Orally promising to deed you the land is one thing. Orally promising to will it to you is quite another as the laws of probate/wills never permit property to pass by an oral agreement, partial performance and parol evidence notwithstanding!
And the fact that you were to manage the ranch until your father's death. Plus, the mentioned terms of his will - although meaningless until upon his death - suggest the latter. That is, it is inconsistent with a promise to deed you the land.
What you need to do is to seek the advice of an experienced and successful real property and probate lawyer.
