Payment protection · Upwork
Upwork disputes and arbitration explained
This page answers one question: once an Upwork payment is contested, what are the steps, deadlines and costs? For what Upwork protection covers in the first place (funded milestones, the desktop tracker, manual time), see Upwork Payment Protection.
Fixed-price disputes, step by step
| Stage | Who acts | Window | If nobody acts |
|---|---|---|---|
| Milestone review | Client approves or requests changes after the freelancer submits | 14 days | See payment protection for auto-release |
| File a dispute | Freelancer, after a refund request on an ended contract or an unreleased milestone | 7 calendar days | Remaining funds are refunded to the client |
| Respond | Client accepts or declines, with evidence | 5 calendar days | Requested funds are released to the freelancer |
| Non-binding resolution | Upwork mediation specialist reviews both sides | Typically within 2 days | — |
| Accept or reject it | Both parties | 2 calendar days | No response or one rejection → Notice of Non-Resolution |
| Opt into arbitration | Either or both parties pay Brief’s fee | 7 days after the notice | See outcomes below |
Two details from Upwork Help matter in practice:
- Evidence is one-shot. Both the freelancer’s dispute form and the client’s response say you cannot edit or add details after you submit. Attach the milestone description, messages and deliverables the first time.
- Feedback first. On an ended contract, a freelancer must leave feedback for the client before the dispute form opens.
- Active contracts. If the client will not end the contract or release payment, Upwork tells freelancers to contact Support with proof the work is complete; only the client can end the contract to trigger the refund-request route.
Arbitration: outcomes and cost
Arbitration is only offered on fixed-price contracts, by email, to parties who qualify. Brief, a third-party company Upwork says is not affiliated with it, makes a binding decision that Upwork upholds. Not complying with the outcome can lead to an account suspension that may block payments or withdrawals.
| Situation | Funds still in escrow | No funds in escrow |
|---|---|---|
| Both decline arbitration | Funds are released to the client | Case closes |
| Both agree and pay | Arbitrator decides; funds move per the decision | Arbitrator decides |
| Only one side pays | Funds are released to the party that paid | The participating party can pay the full fee for a binding decision |
Cost: shown in the arbitration email; usually split evenly; Upwork pays part on contracts over $20,000. For a small milestone, compare the fee in that email with the amount at stake before you opt in.
Practical read for freelancers: because a mutual decline returns escrowed funds to the client, a freelancer who believes the work met the milestone has to be willing to pay for arbitration to keep the claim alive. For clients: ignoring a dispute for five days releases the requested funds to the freelancer.
Hourly disputes (clients)
- Window: from Monday noon UTC until Friday 23:59 UTC after the billing week closes. Contacting Support or requesting a refund does not count as filing.
- Where: the contract’s Timesheet tab → Dispute. You cannot dispute more hours than were billed that week.
- Grounds: billed hours only. Quality complaints are not grounds for an hourly dispute.
- Process: the freelancer has three calendar days to accept or decline; an Upwork specialist reviews the Work Diary against Hourly Protection criteria. Upwork says you will know the result within seven calendar days.
- Withdrawing releases the funds to the freelancer, and you cannot re-file for that week.
- Refund requests (not disputes) can be made for payments released up to 365 days ago; refunding is at the freelancer’s discretion.
Freelancers protect themselves on hourly work by meeting the tracker and memo rules listed on Upwork Payment Protection. Choosing between contract types: hourly vs fixed-price contracts.
Before it gets to a dispute
- Write milestones that can be judged against a deliverable, so a mediator can compare the work with the description. General guidance: escrow and milestone payments.
- Keep scope changes and approvals in Upwork messages; anything agreed off-platform is outside Upwork’s process (off-platform payment rules).
- Clients writing a brief that holds up in review: hiring brief template (sister site).
