ADM.4:5.2 - The amount differs
Now suppose P’s account concerns 300 and Q reports a credit of 290. The handler first asks what each amount measures. A fee, a gross-versus-net distinction, another transfer or a genuinely incorrect claim could change the answer.
If evidence establishes a 300 gross transfer and a 10 fee, those quantities can be compatible descriptions. Whether the payer’s obligation is discharged still depends on the applicable payment conditions. If the evidence is unavailable, the handler preserves the unresolved credit or fee claim and obtains the needed source result. Neither a shared reference nor a familiar payment status settles it.
