re: Do you need a lawyer for probate?

If it's truly that straight forward, it won't cost you all that much in attorney fees. Either way, you're going to pay filing fees. I wouldn't imagine more than 10-15 billable hours, but that's strictly a semi-educated guess on my part. 4-5 instruments filed (Application, LWT, Inventory, Judgment of Possession). As much as I'd want to do it myself, too, I'd probably pay the attorney for peace of mind.
