I don't know how to do it, but you should talk to your mother about this and get it legal before she dies, My aunt and uncle did not intend for his family to get my aunt's royalty, they didn't even include it in their will, but I told the attorney when she died about her royalty and he insisted it be included, all of my uncle's family signed a wavier because it was not their family's but one niece would not, I should have found another attorney, I will regret telling him to my dying day. Get it legal before she dies!!! BLStringfellow
