My sister promised to split our inheritance. She lied and kept everything. What are my options?


So… Your Sister Pulled A Fast One?

Your sister said you’d split the inheritance. You believed her. Then she kept everything. Ouch. This isn’t just family drama—it’s real money, and possibly a legal mess. Let’s unpack what’s going on and what you can actually do about it.

Did She Actually Promise, Or Just Wink at Thanksgiving?

First things first: Did your sister ever write it down? A text, email, or even a sticky note saying “I’ll split it with you” is way better than a vague holiday promise over pie. If you’ve got receipts—keep them safe.

What’s In The Will? (And Yes, You Need to Read It)

You might not want to stare at legalese while you're grieving, but the will or trust is key. It’s the playbook. If it says she gets everything, you’ve got a steeper hill—but not an impossible one. Read every word.

Was She The Executor? That Changes The Game

If she’s the executor (a.k.a. estate boss), she’s legally required to follow the will’s rules—not make up her own. If she went rogue, that's not just shady—it could be illegal. Executors don’t get to play Monopoly with real assets.

You Can Ask For A Full Accounting (And You Should)

You're not being greedy—you’re asking for transparency. You’re entitled to know what assets existed and where they went. If she’s acting sketchy or silent, ask for a court-ordered accounting. It's like turning the lights on in a dark room.

Check If You Were Supposed to Get Anything

Were you actually named in the will or trust? If yes, and you got zilch, red flags should be waving. That could mean mismanagement, a mistake, or worse. If no, keep reading—there still might be a way forward.

No Will? No Problem—The Law Has a Backup Plan

If your loved one didn’t leave a will, state law (called intestacy law) steps in. And guess what? In many cases, siblings share equally. If your sister took everything anyway, she might be legally out of line.

Grab All the Evidence You Can (Yes, Even Screenshots)

If you’re going to battle (or just a tough conversation), bring your receipts. Texts, emails, voicemails—anything where she promised to split things helps your case. Even old group chats or “accidental” social posts can be useful.

Lawyer Up (Don’t Worry—It’s Not As Scary As It Sounds)

You don’t need to march into court tomorrow. But chatting with a probate or estate attorney—even for 30 minutes—can help you understand your rights. Many offer free consults. Think of it like talking to a guide before entering the jungle.

Try Mediation Before Going Full Courtroom Drama

If a lawyer is a guide, a mediator is a referee. Mediation is like a family meeting—but with rules. It can save time, money, and relationships. If your sister is remotely reasonable, this might help avoid a legal cage match.

Was She A Little Too Close To The Deceased?

If your sister controlled the money, medication, or mail near the end, and the will suddenly changed in her favor, that might be a case of undue influence. Basically: Did she guilt-trip or pressure her way into a bigger slice?

Some Assets Skip The Will Entirely

Life insurance, bank accounts with “payable on death,” and joint property don’t care what the will says. These go straight to whoever’s named. If your sister is cashing in through those—it's legal, but still possibly challengeable in some scenarios.

Watch For “Sneaky Moves” Like Early Transfers

If property or cash started disappearing before or right after the funeral, you might be looking at fraudulent transfers. That's a big deal. Courts hate it when people try to move money off the table before it’s time to deal.

Get Ready For The Emotional Rollercoaster

You’re not just dealing with money—you’re dealing with betrayal, grief, and possibly guilt. Fighting with family is exhausting. Be honest with yourself: Are you ready for the emotional toll? Therapy isn’t just for bad days—it’s for stuff like this.

Don’t Wait—Legal Clocks Are Ticking

Every state has a time limit (called a statute of limitations) for inheritance challenges. Wait too long, and the law won’t help, even if your case is rock solid. So don’t hit snooze on this—act now, even if it’s just research.

Was She Power of Attorney Before The Death?

This one matters: Power of attorney ends when someone dies. If your sister was using that power to shuffle money around before the funeral, the court might see that as shady—or even criminal. Keep an eye on those transactions.

Ask Yourself: What Do You Really Want?

Do you want your fair share? An apology? Accountability? Closure? Think hard. It’s okay to want justice—or to just want peace. But knowing what outcome you're chasing will help guide every conversation and legal decision from here on out.

Courts Can Fix It—Sometimes In A Big Way

If she broke the rules, she could be ordered to pay you, share the estate, or face penalties. Judges take fiduciary breaches seriously. So yes—justice can happen. You just have to start the process and stay strong.

Staying Silent = Letting Her Win

Maybe you’re scared of drama. Maybe you don’t want to be “that person.” But silence helps the person who took what wasn’t theirs. Even a lawyer’s letter can change the whole tone. You don’t have to shout—just speak up.
