Siblings Threatened to Sue Over an Inheritance After One Relative Refused to Share What Was Left to Them

By the time their father died, the family had already been broken for years.

The original poster’s brother, “Mark,” and sister, “Jenna,” had not simply drifted away. According to the poster, they had taken money from their father long before his death and then turned on him when there was no more to take.

Ten years earlier, their father had given Mark and Jenna $150,000 each. It was meant as an advance on their inheritance, money they had begged for so they could start businesses. At the time, their father was financially comfortable enough that he could help them. But the money did not turn into stability. The poster said both siblings burned through it within two years on things like vacations and cars, then came back asking for more.

Their father refused.

That refusal changed the family.

Mark and Jenna allegedly stopped visiting. They kept their children away from him. They told relatives he was greedy and hoarding money that should have gone to them. The father, who had already given them a life-changing amount, was painted as the villain because he would not keep funding them.

The poster was the one who stayed.

They took their father to medical appointments. They helped him with finances. They were careful not to take money for themselves, saying they had their own stable career and did not need to dip into his accounts. When he entered hospice, they were there. At the end, according to the poster, it was just the two of them: the parent who had been abandoned by two of his children, and the child who had remained.

Then the will came out.

Their father had left the entire estate to the poster. He explicitly disinherited Mark and Jenna. The will also stated that the two siblings had already received their share during his lifetime, which directly addressed the $150,000 each had received years earlier. The poster said the will had been prepared by their father’s longtime lawyer and believed it was solid.

Mark and Jenna did not accept it.

They accused the poster of poisoning their father against them. They began calling and texting. They badmouthed the poster to extended family. Relatives started pressuring the poster to “help them,” as though the money were a family pot to be redistributed according to whoever complained the loudest.

Then the threat became official.

The poster was served with papers. Mark and Jenna were threatening to contest the will, claiming the poster had taken advantage of their father in his old age and used “undue influence” to get him to cut them out. They also made an offer: give them $100,000 each, and they would drop the lawsuit.

That was the part that pushed the poster from grief into fury.

Their father had only been gone a few months. Instead of mourning him, the poster was being accused of manipulating a dying man. Instead of dealing with the estate quietly, they were fielding attacks from siblings who had already taken six figures apiece and then walked away.

The poster shared the situation in the Reddit thread “AITAH for refusing to share my inheritance with the siblings who are now threatening to sue me for ‘undue influence’?”, asking whether they were wrong for refusing to pay and telling their siblings they would see them in court. (reddit.com)

The poster’s anger was mixed with fear. They worried that even if Mark and Jenna had a weak case, fighting them could cost more in legal fees than simply paying them off. That was the ugly pressure of the threat: the siblings did not necessarily need to be right. They only needed to make the process expensive and painful enough that paying them might seem easier.

But commenters urged the poster not to fold.

One of the most important pieces of advice was also one of the simplest: call the lawyer who had drafted the father’s will. The poster had already scheduled an appointment with another attorney, but after reading the comments, they realized the father’s longtime lawyer might already understand the estate, the disinheritance clause, and the history behind the will.

That call changed everything.

A few days later, the poster returned with an update. They had sent the lawyer the legal papers and the texts from Mark and Jenna. According to the poster, the lawyer told them that texts saying things like “it won’t stop until you give us the money” could be considered criminal extortion by letter in California. He contacted the siblings’ lawyer, and the situation began falling apart almost immediately.

Mark and Jenna had apparently lied to their own attorney about major parts of the situation. Their lawyer was not pleased when he learned about the threats and the missing context. The poster said everything collapsed quickly and, to their relief, it did not cost them anything.

But the outcome was not exactly happy.

The legal threat may have been neutralized, but the family damage remained. The poster believed they would probably never see their nieces and nephews again, at least not until the children were older. Extended family members were still angry at the poster, blaming them for “giving” Mark and Jenna “no other options,” as though refusing to hand over $200,000 somehow caused the siblings’ behavior.

That reaction seemed to hurt almost as much as the lawsuit threat itself.

The poster had spent months caring for their father and then grieving him. Now they were being treated as the problem because they would not reward the very people who had abandoned him. Eventually, they decided they would move away once the estate was handled. They wanted peace, and they no longer believed they could find it around relatives who excused threats, lies, and greed.

In the final update, the poster said they had learned the value of keeping receipts. That lesson came at a painful cost: a father’s death, a fractured family, and a legal scare over money that had already been settled in the will.

What commenters said

Commenters overwhelmingly told the poster not to give Mark and Jenna anything. Many argued that paying them would only reward the threat and might encourage them to come back for more later.

Several people focused on the phrase “undue influence” and said it can be difficult to prove, especially when the will was prepared by a longtime lawyer and included language explaining that the siblings had already received their inheritance. Others urged the poster to stop communicating directly with the siblings and send everything through an attorney.

After the update, commenters were especially struck by the texts. Many pointed out how reckless it was for Mark and Jenna to put threats in writing. Some joked darkly that people planning legal pressure should not leave a paper trail, while others said the written messages were exactly what saved the poster from a drawn-out fight.

The strongest reaction, though, was sympathy. Commenters understood that the poster had technically “won,” but still lost a lot: the chance to grieve quietly, the connection to nieces and nephews, and the illusion that extended family would recognize who had actually been there for their father.
