2. Durable Power of Attorney (POA): A Durable POA enables a designated agent to access bills, accounts, sign financial documents, and make financial decisions. The POA enables the designated agent to sign tax returns, pay bills, access bank accounts, life insurance policies, and figure out college tuition issues.Despite the fact that you may be paying for their education, you no longer have access to your child’s college financial or academic records once they turn 18. You can call the registrar and ask to see your 18-year-old’s transcript, or campus tuition, room, and board invoices, but they will not share it with you even though you’re the one paying the bills unless you have a Power of Attorney on file.
