Suing a Computer or Phone Repair Shop for Data Loss or Damage

Device repair disputes have a distinct wrinkle compared to most product/service claims: the harm often isn't just the device itself, but data loss, which can be far more valuable to you than the hardware.

Read the repair agreement's liability terms carefully

Nearly every repair shop has you sign an intake form with liability language — often specifically addressing data loss, sometimes disclaiming responsibility for it entirely, and recommending you back up your device before service. This doesn't necessarily mean you have no case, but it does shape what you're realistically able to claim.

Data loss vs. physical damage: different evidentiary approaches

For data loss:

• Document what data was lost and, if possible, its approximate value (professional work files, irreplaceable photos, business data)
• Check whether the shop's own repair notes or your intake form mention any data backup discussion or warning
• If the shop performed an action clearly unrelated to what you authorized (e.g., a factory reset when you only asked for a screen repair) and didn't warn you, this strengthens your case significantly, since the harm exceeds normal repair risk

For physical damage (new scratches, a screen that stopped working after a different repair, etc.):

• Photos of the device before service, if you have any
• Photos of the damage after
• The specific repair that was authorized versus what type of damage occurred, to establish it's connected to their work

Check for a stated repair warranty

Many repair shops guarantee their work for a set period — if the issue recurred shortly after, or a different issue emerged that appears connected to their repair, check whether their own warranty terms should cover a free correction before pursuing a claim for reimbursement.

Calculating your claim

• For data loss: this is genuinely hard to value unless you can point to specific, quantifiable harm (e.g., you had to repurchase software, redo billable work, or lost specific business records with a calculable cost) — purely sentimental loss (family photos) is real but harder to assign a dollar figure to in a way a court will accept
• For physical damage: the cost to repair or replace the device, or the difference in value if it's now working but degraded

A note on limitation of liability clauses

If your intake form included a liability waiver, it may limit what you can recover — but these waivers don't always protect a shop from claims involving actions clearly outside the scope of what you authorized. This is worth flagging specifically in your case if it applies to your situation.
