Register the version before it leaves your hands
Complete Duo before either party begins work or relies on the shared terms. If the two parties keep different versions, later disagreement can begin with uncertainty about which exact file each person relied on.
What the record shows — and what it does not A ProofReg record makes an exact file version and registration time verifiable. It does not automatically grant copyright or ownership, determine who created the work, or prevent copying. A connected history of source files and revisions can substantially strengthen the evidence behind your account of how the work developed.
