Why is this so unbelieveable? I havn't run across one person that sees this as my mom's final wish and as my sister's WRONG DOING!

The designated POD in this discussion is also the individual chosen as Personal Representative of the estate, the assets are 5 certificates of deposit all w/this same person as POD. Mom assigned POD to her 5cd's back in 2008,she finalized her will w/estate atty. She had "all her ducks in a row", everything lined up.The 5cd's(approx.$55K)avoided probate,were the bulk of mom's estate, this made it eligible for Sum.Admin. Medicaid eligibility was approved & covered her end-of-life Hospice & medical. Approx $9K in mom's personal sv acct for funeral,etc.,misc. First paragraph of her will (in short)states "each of my 3 kids are to receive the amt.of $ in the cd in their name & bal of estate to be split equally amongest the 3 kids". By'08 mom no longer wanted to do the math(5cds$ div by3kids)& put this task onto shoulders of her oldest kid. A banker insisted the 5cd's were not part of estate & were clearly intended 4 sis. Well, she TOOK that bit of info.& ran w/it!
