It seems like you are referring to only pay a partial amount of the funds you have in Escrow. You can release the partial amount to the freelancer, by following these steps:
1. Go to the Jobs tab > My Jobs.
2. Under 'My Contracts' section, find the correct contract and click the Pay Now button.
3. Click Pay. [[ Note: Clicking the 'Pay' button will not release the funds immediately. ]]
4. A pop-up window will appear. Click the Edit (pencil) icon.
5. Edit the amount and select an underpayment reason.
6. Click Send Payment.
