Who Gets Grandma's Bank Account When There's a Co-Owner?
A co-owned bank account may bypass the will entirely. Here's what that means for your family's money.
Here's the situation: Grandma passed away, and your mom was the co-owner on her bank account. The will says split everything equally among the kids. Now the siblings want their cut. So who's right — the will or the bank?
The bank wins. When two people co-own an account with rights of survivorship, the surviving co-owner gets the entire balance automatically. It doesn't matter what the will says. That money never enters the estate — it transfers directly to the survivor the moment the other owner dies. The will is powerless over it.

Does your mom have a moral obligation to share? That's a family conversation, not a legal one. She's under zero legal requirement to hand over a dime. Whether she chooses to keep it all or split it to preserve family relationships is entirely her call. Some people split it to honor the spirit of the will. Others keep it because the law says it's theirs.
The bigger lesson here: pay attention to how financial accounts are titled. Beneficiary designations and joint ownership arrangements override wills every single time. If your family is doing estate planning right now, review every account title and every named beneficiary. A mismatch between a will and account ownership is one of the most common — and most avoidable — sources of family conflict after a death. Continue reading at MarketWatch.com
