Quick Summary

Here’s a summary of why families often fight over joint bank accounts, “payable on death” accounts, and other property held with someone else.

A joint account is a bank or credit union account with two names on it. When one person dies, the survivor often takes the balance automatically.

These accounts can avoid probate. But they can also create confusion, hard feelings, and lawsuits—especially when family members believe the account was added “just to help with bills.”

Why This Matters

This issue shows up all the time after a death.

One child may say, “Mom put my name on the account so I could pay her bills.”
Another child may say, “That money was supposed to be split equally.”
And the person whose name is on the account may say, “The bank told me it becomes mine.”

Here’s the tricky part: Michigan law often starts with a presumption (a strong starting point) based on how the account is titled. In many cases, if an account is set up with survivorship, the law assumes the survivor gets the money when the other person dies.

But that doesn’t end the story.

Families can still challenge the result. The fight usually comes down to questions like:

  • What did Mom really intend at the time the account was created? (the problem here is that Mom isn’t here to testify, and most bank representatives don’t have a clue why Mom set the account up this way — with no testimony, the joint owner wins).

  • Was the account set up because someone pressured her? (very difficult to prove after Mom is gone)

  • Was there fraud? (very difficult to prove after Mom is gone)

  • Did she have the mental ability to understand what she was doing?  (maybe, but this requires medical documentation at the time Mom opened the account which is difficult to get).

  • Was the account truly meant only for convenience? (probate courts require proof — for example, testimony from someone at the bank — at this rarely happens).

And “convenience” is where many families misunderstand things. Helping with bills does not automatically mean the survivor must hand the money back to the estate. The facts and timing matter and, as you can see from the above, hard evidence is not easy to find.

One more important point: banks and credit unions do not always work under the same rules. A joint account at a bank can be treated differently than a multiple-party account at a credit union. Even when the account looks the same to a family, the legal “starting point” can be different.

If a dispute heads to court, it is often handled in probate court as part of the estate process. Sometimes it lands in circuit court instead. Either way, these cases can become expensive, time-consuming, and emotionally draining fast.

And if you’re the personal representative (the person in charge of the estate), there’s added pressure. That role comes with duties. It is not a free pass to “go after” someone out of anger. A personal representative has to act for the estate’s best interests, and court filings must be based on real facts and a real legal basis—not payback.

Simple Lesson

Small choices—like adding a name to an account—can quietly rewrite your whole estate plan.

Action Step

Take 20 minutes and make a simple list of your major accounts and how each one passes at death.

If you have any joint accounts, ask yourself:

  • “Do I want the survivor to keep this money?”

  • “Or am I doing this only to make bill-paying easier?”

If it’s only for help, there are much better and safer ways to set that up without creating a future family fight.
