How do I liquidate my mom’s common stock to qualify for Medicaid?

Do you have a POA over your mom's finances and do you know who her stockbroker or what financial company that sold her the stock? If the answe is yes, then call the stockbroker/financial company and talk to them explaining that you have a POA and you want to sell her stock then he/she can advise you on what you need to do to have the stock sold.

Is there not a branch of the bank that holds the CD in MD? I would think you could do it via fax and notary. Is it mature? If not can it be part of her allowable assets until it matures then you can cash it out or renew it.

Do you have access to mom's documents? She might have a brokerage account already set up and that is where you would sell the stock from. If not, Google it and try to find the cheapest route. You can also contact the company and find out if they are buying the stock.
