How do we remove Mom's name from CDs that she jointly owns with my dad?

Depending on which state your mom lives in, she is allowed to have a certain amount of assets in her name after she has been approved for Medicaid. It is usually minimal, like $2,000, but you should check out the number in her state. Regarding the CDs, whose name is first on the joint CDs? If it is your Dad's, then they are being reported under his social security number and it is easy for the bank to take your mother's name off. Either your mother or her power of attorney can sign the bank's form for change of ownership. If your mom's name is first, then you want to change the account to your father's name and social security number. Again, the bank can provide you with the appropriate form to sign. In this case, the bank will have to open a new account for your father.
