UPDATE: AITA for suing my brother over a family heirloom he gave to his fiancée?

Wow, I wasn’t expecting this much attention on my post. Thank you to everyone who shared their thoughts and advice. I wanted to give an update because things have escalated and there’s some new context.

First, I talked to my parents about the situation. It turns out my brother didn’t just take the necklace he convinced my dad that grandma told him it was meant for him because she thought a man would be more responsible. My dad, trying to avoid conflict, handed it over without asking questions. So no, my dad didn’t intentionally give it to him, it was manipulation.

I also reached out to other family members who remember grandma’s clear wishes that the necklace was supposed to go to the first daughter. They’re willing to back me up if this goes to court. My dad has also agreed to speak on my behalf in court, clarifying that he never meant to give the necklace away permanently.

As for the legal side, I’ve consulted with my lawyer, who thinks I do have a case. Since there’s no will, it all comes down to proving that the necklace was meant to stay in the maternal line. It’s tricky, but I feel more confident now knowing I have some family members on my side.

My brother and his fiancée, however, have doubled down. They’ve accused me of being jealous, and his fiancée posted another passive-aggressive picture on social media wearing the necklace, captioning it “Some things just find their rightful home❤️.” It’s honestly infuriating.

At this point, I’m committed to fighting for the necklace, even if it causes more tension in the family. I’ll keep you updated if there are any major developments.
