A Customer Hands You Their Own Contract to Sign: Decision Tree
Why this matters
Most contract advice assumes you wrote the document. Plenty of the time you did not. A general contractor, a property manager, a builder, or a savvy homeowner hands you their paper and a pen and expects a signature so the job can start. That document was written to protect them, not you, and once you sign it governs. Signing a stranger's contract without reading it is how shops end up covering damage they did not cause, waiting months to get paid, or eating a warranty they never agreed to.
Start here: do not sign under time pressure
The one move that protects you is refusing to sign anything on the spot just because someone is standing there waiting. "I sign everything after I have read it" is a complete, professional answer. A contract you have not read is a risk you cannot price. Nobody legitimate loses a good sub over a one-day read, so if the pressure to sign now is heavy, treat that as a warning about the document, not a reason to rush.
Sort what you were handed
Figure out what the document actually is before you react:
- A subcontract or work order (GC or builder): the meaty one - full terms, pay-when-paid, indemnity, backcharges.
- A master services agreement (property manager, facility): governs many future jobs, not just this one.
- A vendor or compliance packet: insurance requirements, tax forms, safety acknowledgment. Lower risk but still binding.
- A homeowner's own form: rare, usually harmless, occasionally a trap copied off the internet.
The type tells you how hard to read and how much is at stake.
Walk the tree
Small job, short standard form? Read it once for the four killers below, and if none appear, signing is usually fine. Small, simple, and standard is the low-risk lane.
Does it contain any of the four killers? These turn a routine job into a loss:
- Pay-if-paid: you only get paid if the GC gets paid by the owner. Their collection problem becomes yours.
- Broad indemnity / hold harmless: you agree to cover their liability, sometimes even for their own negligence. See related: The Hold Harmless and Indemnity Clause in Plain Language.
- Backcharge / offset language: they can deduct costs from your payment with little proof.
- Open-ended warranty or "to owner's satisfaction": a subjective standard you can never definitively meet.
If one appears, do not sign as-is. Move to negotiate.
Can you strike or soften the killer clause? You are allowed to redline. Cross it out, initial it, and hand it back, or send a short email: "Happy to sign once we adjust the indemnity to cover only our own work." Many one-sided clauses are boilerplate the other side will trade away to keep the schedule. If they agree, get the change in writing and initialed by both sides. A verbal "don't worry about that clause" is worth nothing.
Do they refuse to change a genuinely dangerous term? Now it is a business decision made with eyes open. If the job's profit cannot absorb the risk the clause creates, walk. A job you decline is cheaper than a job that sinks a bad month.
Big-dollar, long-term, or unusual counterparty (commercial, government, large estate)? Get an attorney's eyes on it first. A one-time flat-fee review of a master agreement you will use for years is one of the best-value legal spends a shop makes.
Options at a glance
| Situation | Move |
|---|---|
| Short standard form, no killer clauses | Read once, sign |
| One-sided clause, boilerplate | Redline, get change initialed |
| Dangerous clause they will not change | Price the risk or walk |
| High-value or multi-job master agreement | Attorney review first |
| Anything you do not understand | Stop, ask, do not sign around it |
Recap
- Never sign under same-minute pressure.
- Identify the document type.
- Hunt the four killers: pay-if-paid, broad indemnity, backcharges, subjective completion.
- Redline what you can, in writing and initialed.
- Walk from a risk the job cannot cover; lawyer up on the big ones.
Keep a signed copy with every initialed change. The version in your file, matching theirs, is what protects you if the job goes sideways.
