My takeaway from this relates less to a bike shop or personal recordkeeping/legalities.
It reflects on dishonesty from essentially a handshake deal. Geez...can't trust anybody nowadays...
P.S. The OP's copy of the paperwork might not say anything other than the shop shares in the sales proceeds.
50% of zero (like if it got stolen or donated) equals zero. The LBS likely does not absorb any financial responsibility.
