If you don't have a multisig or social recovery wallet, imo the next best is to split up your seedphrase with a "poor man's 2-of-3": chunk 1 is top + middle, chunk 2 is middle + bottom, chunk 3 is bottom + top.

We could even use the kind of paper that people use to sign two copies of a form at the same time for this:

Love the simplicity of this method! However if you do this for 12 word seed you only need to brute force about 33 bits of entropy to crack the seed from one of the shards. IMO this method is one of the main use cases for a 24 or 36 word seed. For a 36 word seed each shard needs around 128 bits of entropy to crack.

I just saw that you added to your cast with this info :)
