Better than storing 50% of key somewhere as for most bitcoins wallets /accounts it is only possibility.
If you are not so newbie maybe TRY ethereum multisig wallet or other multisig wallet.
Those wallets use few keys to unlock funds for example 3 of 5 keys.
Then store them like
1-2 to your lawyers and/or notary with your last will
Keep for yourself other keys like 3 in different computers/drives/family members/best friends and locations of your choice if printed or engraved on steel
In such case no password is needed if you are dead so family members after reading your last will can retrieve funds.
If your house burn you can see your last will and documents in lawyer company and retrieve keys from friends so you will be able to retrieve funds. Unless your lawyer your notary and your family and friends conspire against you, but then it is already a hard time for you.
There is a risk that If you get hacked and all keys stolen then nothing will help you.
