Consider getting married. Should I tell my fiancée I own 10 btc?
If getting divorced in future, will she take 5 away from me? I don't plan to touch those BTC for long long time, should i just keep secret?

UDATE: thank you all for your suggestions and I am going to follow u/penduR7 's suggestion by moving 0.1 btc to a decoy wallet. and keep other in a new paper waller and only keep 24w in my brain.

And who knows, maybe one day 0.1 btc can buy us a good nice car. and she will be happy the same. (lol)

Thank you all and have a great day/night.

UPDATE 2 with a confession. I was divorced before . My ex hooked with a dude in her gym. She divorced me and took the small town house we had ( with mortgage for sure ) I was young , around 29 so I didn’t lawyer up and gave her everything and moved from East coast to California. After about 5 years now I am in a pretty okay relationship . But if you ask me if I can fully trust another women ? God no. That’s my confession. Sorry . I hid this info initially .
