My grandmother had temperary custody of me when I was young and my father was inprisoned my grandmother took care of me until I was 18 years old now she passed away with no will and my sperm donar and uncle are trying to take it away from me. They are also doing illegal things on the property.They also sold timber and my grandmother never wanted that to happen and I never seen a share of any money

With no will your grandmother's estate is subject to the laws of inheritance in your area. ANY question on law NEEDS to include your general locale as laws vary.

Most likely your father and uncle (his brother?) have legal claim on the estate.

Normally you have no "share" of anything. Your grandmoters children (? Your father and uncle) would be the heirs and normally you will not have any right to any of it.

And once they take ownership of the land, they are free to sell the timber if they want to, Your grandmothers wishes do not have to be followed.

She should have done a will or put you on the deed or something, by doing nothing, she allows the laws of the area to decide who gets what.

Her just raising you ( while wonderful) gives you no special rights
