Who Is Liable When a Subcontractor Causes Damage

Why this matters

"They were a sub, not my guy" does not get you off the hook with the customer. When a sub damages property or injures someone, the customer looks to the company they hired, which is you. Whether that loss lands on you and stays there, or moves back to the sub where it belongs, depends entirely on how you set the relationship up before the job. Understanding the liability chain is what keeps a sub's mistake from becoming your uncovered loss.

The chain: you are liable to the customer, the sub is liable to you

Liability runs along the contracts. The legal term is privity, the direct contractual relationship between two parties.

• The customer contracted with you. They have privity with you, not the sub, so they look to you to make the damage right. To the customer, there is one company on the job.
• You contracted with the sub. You have privity with them, so you look to them to cover what their work caused.

Two links, and you sit in the middle. The customer's claim comes at you from one side; your recovery goes at the sub from the other. If the second link is weak, you absorb the loss with nothing to pass it to.

The "independent contractor" myth

Hiring a sub does not automatically shield you from responsibility for what happens under your name. Several doctrines can keep the loss on you:

• Vicarious liability, where a hiring party is held responsible for the acts of someone working on their behalf, especially where you directed or controlled the work.
• Non-delegable duties, certain safety and code obligations the law does not let you hand off just by subbing the work out.
• Negligent selection, being on the hook for hiring a sub you knew or should have known was unqualified or uninsured.

The practical read: subbing the work out does not sub out the responsibility. It just gives you a party to recover from, if you set that up.

The tools that push the loss back to the sub

Three tools work together to move a sub's loss off your books. One without the others is thin.

• Indemnity. A contract term where the sub agrees to cover losses arising from their work, including your defense costs. The clause types and enforceable limits are their own subject; see the related indemnification article.
• Additional insured. An endorsement adding you as a covered party on the sub's own liability policy, so their insurance can respond directly to a claim from their work.
• Certificate of insurance (COI). The document proving the sub's coverage is real, current, and adequate. Verify it with the carrier; do not just file the copy the sub hands you.

An indemnity promise from a sub with no insurance behind it is empty, because a party with no money cannot pay. Insurance is what makes the promise real.

What breaks the chain

The link to the sub fails in predictable ways, and each one leaves the loss on you:

• No written agreement, so there is no indemnity term to invoke.
• No COI, or an expired one. You have no confirmed coverage to reach, and your own carrier's audit may treat the sub's work as your own payroll, raising your cost.
• A judgment-proof sub, one with no assets and no coverage. A claim against them collects nothing.
• Your own crew partly at fault. Shared fault muddies and may reduce what you can recover.
• Anti-indemnity statutes. Many states limit how far you can shift fault by contract, and some void broad clauses that make a sub cover your own negligence. The limits vary by state, so confirm with an attorney what holds where you work.

Set it up before the job

The entire outcome is decided before anyone lifts a tool. For every sub, every time:

1. A written agreement with an indemnity term appropriate to the work.
2. A current COI that names you as additional insured, verified as active.
3. The documents on file, with the expiration tracked so coverage does not lapse mid-job.

The judgment to bank: you cannot control whether a sub causes damage, only whether the loss has somewhere to go when they do. That is built in the paperwork, not in the moment.
