Update: aitah for telling my wife to tell her mom to move out after she decided to leave all her inheritance to her brother?

We all know that moment when family obligations clash with basic fairness. For one married couple, stepping up to help an aging parent quickly morphed into an exhausting, unpaid second job. They spent months pouring sweat and money into restoring a neglected property, all while watching a wealthy, capable family member sit back and do absolutely nothing.

The situation reached a boiling point when the favored son—who inherited everything—refused to lift a finger or share the wealth, preferring to play video games instead of taking responsibility. As family boundaries collided with modern realities, the couple had to make a tough call. Will their ultimate boundary finally force a grown man to grow up, or just tear the family further apart? Curious how it all unfolded? The juicy details are right below.

Couple Renovates Mother-In-Law's Home For Free While Her Wealthy Son Plays Video Games All Day

Update: aitah for telling my wife to tell her mom to move out after she decided to leave all her inheritance to her brother?

The dust had finally settled after the initial shock, but the reality of their new family dynamic was far from perfect.

Our original conclusion was to have BIL return his portion of the inheritance to his mother, who, I again would like to mention, had practically zero retirement savings. As this...

My wife received nothing. To make matters a bit annoying, his share sits in a checking account earning no interest.

Edit: Wife is added to the title as well, and with MIL's inheritance, there is practically no risk of default.

Looking at this couple’s exhausting battle with their brother-in-law, the friction in this household fundamentally comes down to how to stop a cycle of enabling before it ruins the family entirely. Family psychology specialists often point out that financial enabling—continuously bailing out or providing for an adult child who is capable of independence—creates a cycle of dependency that hinders personal growth.

By allowing the brother-in-law to live with them while hoarding his inheritance, the couple inadvertently shielded him from the natural consequences of his inaction. To break this dynamic, the couple needs to enforce strict boundaries regarding their living space.

A practical next step would be giving the brother a formal 30-day notice to move out, forcing him to utilize his inheritance to secure his own apartment. This shifts the responsibility entirely back onto his shoulders, removing the safety net that currently allows him to avoid adulthood.

Navigating weaponized incompetence within a family unit is never easy, especially when inheritance money complicates the dynamic. The couple’s decision to finally step back and force the brother to face his own consequences marks a massive shift in their household.

Do you think the couple was right to finally cut off their help, or should they have been more patient with family? And what about the mother’s role in enabling him for so long?

u/Late-life-edit KICK HIM OUT!!! He's a grown man who can afford an apartment. I understand that the issue with MIL is a little more complicated, but you owe him nothing....

u/Wtopp3 He will crash out eventually, spend every dime, and will want money from you and mom. Hold the line.

u/SpillThatTea2Me I’m afraid your BIL will need to figure it out or not. It’s time for him to spread his wings and fly.

A few commenters pointed out that the cultural defense doesn’t hold up when the math is this unfair.

This situation highlights how difficult it can be to navigate inheritance conflicts when emotional ties and living arrangements complicate the picture. Was OP right to finally cut off the brother, or did they let the situation drag on too long? And how would you handle a sibling who hoards the family money but expects free housing?
