What is a Subcontractor Agreement?

This template is written for contractors, subcontractors and project owners, so that both sides can see what was promised, what it costs, and what happens if circumstances change.

19 details are captured across 6 areas: parties and contact details, scope and deliverables, payment and financial terms, dates, timing and duration, site, materials and permits, and legal protections and risk. Together they fix what the contractor owes the employer, measured in programme milestones rather than in adjectives.

Disputes tend to surface around practical completion, when one side considers the obligation discharged and the other does not. Construction disputes concentrate around three points: extra work performed without a written change order, payment withheld at the end of the job, and defects appearing after the final invoice.

The preview updates live as you complete each field, so you can review the exact language before downloading it as PDF or Word. Treat the result as a well-organised first draft: sound in structure, but worth an attorney's review where the sums involved are significant or the situation is unusual.

What matters most in a subcontractor agreement

Flow down main contract terms

Subcontracts should mirror the relevant obligations of the main contract so the contractor is not caught between inconsistent terms.

Retention release

Tie the final release to completion of the punch list and any required certificates, and state the deadline for release.

Preliminary notices have hard deadlines

Mechanics' lien rights commonly depend on serving notices within a strict window. Miss it and the right can be lost entirely.

When you need a subcontractor agreement

  • When money changes hands: Record what the employer owes, when each programme milestone falls due, and what follows a late payment. These are the clauses relied on most often and left vague most often.
  • When the arrangement will repeat: For a relationship that runs across several jobs or periods, agree the standing terms once and let each instance sit under them rather than renegotiating from scratch.
  • When instructions given verbally on site and never confirmed is a realistic prospect: If this is the way the arrangement usually goes wrong, it belongs in the document. Allocating that risk in advance is much cheaper than allocating it afterwards.
  • When the counterparty is new to you: With no track record between the parties, the written terms do the work that familiarity would otherwise do. That is exactly when precision pays for itself.
  • When the works needs defining: Write down what is included and what is not. A specific description is what turns an extra request into a chargeable variation rather than an argument.
  • When replacing an earlier arrangement: Issue a fresh subcontractor agreement when the original terms no longer reflect what the parties actually do. Amending informally leaves two inconsistent records of one relationship.

What to include in a subcontractor agreement

This generator collects 19 details. Here is what each group covers and why it matters when the document is relied on.

Parties and contact details

Get these right before anything else. A dispute over the works is unwinnable if the document names a party that does not legally exist.

Contractor Name
The full legal name of the contractor or business performing the work, matching the name on invoices and tax records.
Contractor Address
The contractor's business address for notices and payment correspondence.
Subcontractor Name
The legal name of the subcontractor performing part of the work under the main contract.
Subcontractor Address
The subcontractor's business address for notices and payment.

Scope and deliverables

Measure the works rather than describing it. A scope stated in programme milestones can be checked at practical completion; one stated in adjectives cannot.

Project Description
The nature and extent of the project, including location and principal elements of work.
Scope of Work
A precise description of what is included — and, just as importantly, what is not. Scope creep is the leading cause of disputes on service contracts.

Payment and financial terms

Tie each payment to something observable — a delivered programme milestone, a date, or practical completion — rather than to a general sense that enough has been done.

Contract Price
The total price for the completed work, and whether it is a fixed sum, cost-plus or subject to measured rates.
Payment Schedule
When each payment falls due, tied to dates or milestones. A clear schedule is the most effective protection against slow payment.

Dates, timing and duration

Use calendar dates, not relative triggers. "On approval" cannot be located on a calendar, which means it cannot be used to show that anyone is late.

Effective Date
The date the agreement takes effect. This can differ from the signature date, and it is the date obligations start running from.
Start Date
When performance begins. Tie this to a calendar date rather than a vague trigger such as 'on approval'.
Completion Date
The date by which the work must be finished, and whether that date is a firm deadline or a target.
Warranty Period
How long the work is guaranteed after completion and what the warranty actually covers.

Site, materials and permits

Tie these details to the construction programme and the drawing set. Verbal instructions given on site are the single most common cause of construction disputes.

Project Address
The site address where the work will be carried out.
Materials Responsibility
Who supplies and pays for materials, and who bears the risk of price increases or shortages.
Change Order Process
How variations are requested, priced and approved. Requiring written change orders before extra work starts prevents most billing disputes.
Permits Responsibility
Who obtains and pays for permits and inspections. Unpermitted work can force removal at the owner's cost.

Legal protections and risk

These are the clauses nobody reads until something goes wrong, at which point they are the only clauses that matter.

Insurance Requirements
The cover each party must carry, the minimum limits, and whether the other party must be named as an additional insured.
Termination Terms
What happens on termination — final payment, return of property and which clauses survive.
Governing State
The state whose law governs the agreement. Choose a state connected to the parties or the work, as a wholly unconnected choice may not be respected.

Completing this subcontractor agreement

Attaching the construction programme and the drawing set

The construction programme and the drawing set carries most of the evidential weight here. Attach it as a schedule and refer to it by name in the body, rather than leaving it as an email nobody can find later.

Describing the works

The strongest version of this subcontractor agreement describes the works in terms someone outside the deal could check — quantities, programme milestones, dates and standards. Write it so a reader who was not in the room can tell whether it has been done.

Not stopping at practical completion

The defects period and the retention released at its end continues past that point. Give it its own clause, because obligations that are merely assumed to survive often do not.

Making the counts checkable

Where the price depends on programme milestones, keep a contemporaneous record as they are delivered. A count reconstructed at invoice time invites a challenge that a running record would have prevented.

Checking the consents

Where a landlord, lender, insurer or licensing body has to approve the arrangement, obtain that approval before practical completion rather than assuming it will follow as a formality.

Common mistakes to avoid

  1. No inspection or review window. Give the employer a defined period to check the works and raise problems, with deemed acceptance after it. Otherwise work sits "under review" indefinitely and payment never falls due.
  2. Verbal instructions on top of a written contract. Once instructions start being given by phone or in passing, the written agreement stops describing the arrangement. Confirm changes in writing the same day.
  3. No route out. Agree how the arrangement ends while the contractor and the employer still get on. Exit terms negotiated during a dispute rarely favour anyone, and they cost far more to settle.
  4. Variations agreed on site. Instructions given verbally to whoever is on site are the single biggest source of construction disputes. Price and confirm every variation in writing before the work is done.
  5. Skipping the notice details. Say where notices go, in what form, and when they count as received. Agreements fail at this point more often than at the clauses people actually negotiate.

How to use this subcontractor agreement generator

  1. Fill in the form. Work down the 19 fields in order. The ones describing the works carry the most weight, so give them more than a few words — everything else in the document refers back to them. Nothing is sent to a server — the document is assembled in your browser.
  2. Read the preview. Check the preview against the construction programme and the drawing set. Where the two disagree, the document is the version that will be relied on, so fix it here.
  3. Download and sign. Take the PDF for signing or the Word version for further edits. Make sure the signed copy reaches everyone named, since a document held by only one side is hard to rely on.

Subcontractor Agreement — frequently asked questions

What is the difference between a conditional and unconditional lien waiver?

A conditional waiver takes effect only when the payment actually clears; an unconditional waiver takes effect immediately on signing, regardless of whether you are paid. Signing an unconditional waiver in exchange for a cheque that later bounces means the lien right is gone and the debt is unsecured. Always use the conditional form until funds have cleared.

Who should sign the subcontractor agreement?

The contractor and the employer, through someone with authority to bind them. Where either is a company, that means a director or an officer with delegated authority — a signature from someone without it is a defence waiting to be raised.

Does anything survive after the subcontractor agreement ends?

Yes. The defects period and the retention released at its end continues past practical completion, and confidentiality obligations normally do too. Anything expected to survive has to say so expressly — an obligation that is merely assumed to continue generally does not.

Which state's law should govern this subcontractor agreement?

Choose a state with a genuine connection to the parties or the subject matter — where a party is based, or where the work or property is located. A choice with no connection at all may not be respected, and for property or employment the local state's rules will often apply regardless of what the contract says.

Do change orders really need to be in writing?

Yes, and this is worth being strict about. Verbal instructions to do extra work are the most common reason construction invoices go unpaid, because at the end of the job there is no record of who authorised what. Get the variation priced and signed before the work starts, however small it seems.

Does a contractor need to be licensed for this work?

Most states require a licence above a fairly low dollar threshold, and the threshold and trade categories vary. An unlicensed contractor may be unable to enforce the contract or recover payment at all in some states, so verify the licence before signing.

How should progress payments be structured?

Tie each payment to a completed, inspectable stage — foundation, frame, rough-in, finish — rather than to calendar dates. Hold a retention of five to ten percent until final completion so there is a financial incentive to finish the snag list.

Is this subcontractor agreement free to use?

Yes. Every template on the site is free to complete and download as PDF or Word, with no account, no email address and no payment. There is no premium tier holding back clauses, and you can generate as many versions as you need.
