Yes, but I am also a joint owner on my Mom's bank accounts. Since I retired I have become more involved and am transitioning to setting up a lot of her bills as auto-pays.
Several years before my Dad passed away, he and my Mom had their Will, POA, POA for medical, and other estate papers, drawn up by their attorney. Then after my Dad passed away, my Mom had her attorney make the necessary changes to the existing estate paperwork back in about 2001. She and I talked to her attorney last year about a some possible issues and concerns that could arise after her demise, involving one of my siblings.
So after discussing things with her attorney, Mom had him draw up new POA, POA for medical, a Revocable Living Trust (she's the trustee and I'm the successor trustee), and a pour over Will (with me named as the executor). All of her financial and investment accounts already had designated beneficiaries. And, in keeping with my Dad's wishes, she made me joint-owner on her bank accounts and CDs after he passed away, so I can take care of all of the banking and financial matters for her.
If I precede my Mom in death, or am otherwise incapable of fulfilling my role of executor or successor trustee, then my two siblings are named as secondary joint-executors of her will, and as secondary joint-successor trustees of her RLT. They both live nearly 1,000 miles away, have never really shown much interest in my folks financial or health matters, and have chosen not to really stay much in touch with Mom. They usually each call her a couple times a year.
Although she has always kept her finances pretty well organized, I've assisted her to get everything completely squared away financially, and have all of the recurring bills set up on auto-pay. Her current supplemental health insurance, through my Dad's former employer, is being terminated by the company at the end of this year, so I assisted her in getting signed up for new medigap and prescription drug plans. We set up auto-pay for her medigap premiums, and I will get the drug plan set up that way too.
With everything organized and pretty much on auto-pilot, she is much more at ease, and has a lot less to worry and stress over. Her biggest concerns now are what we're going to have for breakfast and dinner tomorrow.
