Can you sue a contractor in Colorado without a written contract?
Yes. In Colorado, the absence of a signed written contract does not necessarily prevent a homeowner from bringing a claim against a contractor. Depending on the facts, an enforceable agreement may arise from an oral agreement, the parties’ conduct, written communications, invoices, payments, or other evidence showing what the parties agreed to do.
A written construction contract makes it much easier to prove the scope of work, price, schedule, warranties, and other terms. But when no formal contract exists, courts may still look at the parties’ communications and conduct to determine whether an agreement was formed and what obligations arose from it.
How Can a Construction Contract Exist Without a Signed Agreement?
A construction agreement does not always have to be contained in one signed document.
Oral Agreements
A homeowner and contractor may enter into an agreement verbally. The enforceability of an oral agreement depends on the particular facts and the terms of the agreement. Colorado’s Statute of Frauds requires certain agreements to be in writing, including some agreements that, by their terms, cannot be performed within one year.
Contracts Implied by Conduct
An agreement may also be inferred from what the parties actually did. For example, evidence that a contractor agreed to perform particular work, began the project, accepted payments, sent invoices, discussed change orders, and communicated about the project may help establish the existence and terms of an agreement even when no formal contract was signed.
What Evidence Can Help Prove an Unwritten Construction Agreement?
When there is no signed contract, evidence showing what the parties said and did becomes especially important. Useful evidence may include:
- Texts and emails discussing the scope of work, price, schedule, materials, change orders, or completion dates.
- Proposals, estimates, and invoices identifying the work to be performed and the amount charged.
- Payment records such as checks, credit-card payments, bank transfers, or receipts.
- Photographs and inspection reports documenting defective, incomplete, or abandoned work.
- Permit and building records showing the contractor’s work on the project.
- Witness testimony from subcontractors, suppliers, inspectors, or others familiar with the project.
What Claims May Be Available Without a Written Contract?
The claims available depend heavily on the facts. Depending on the relationship between the parties and the type of project, possible claims may include breach of contract, breach of applicable implied warranties, negligence, promissory estoppel, unjust enrichment, or other equitable remedies.
Colorado recognizes implied warranties in certain residential construction circumstances, including warranties associated with workmanlike construction and habitability. The scope of those warranties depends on the nature of the transaction and the parties involved.
Colorado law also recognizes that certain duties involving construction can arise independently of a written contract. The Colorado Supreme Court’s decision in Cosmopolitan Homes, Inc. v. Weller, for example, addressed duties associated with defective residential construction. The availability of a negligence claim, however, depends on the particular facts and applicable law.
Equitable doctrines such as unjust enrichment, quantum meruit, or promissory estoppel may also become relevant when the parties’ relationship or conduct does not support a straightforward written-contract claim.
Why a Written Construction Contract Still Matters
Although a homeowner may have legal remedies without a signed contract, a written agreement can prevent many disputes by clearly establishing:
- the scope of work;
- materials and specifications;
- contract price and payment schedule;
- procedures for change orders;
- project deadlines;
- warranties;
- responsibility for permits and inspections; and
- procedures for resolving disputes.
When a construction relationship breaks down and there is no signed agreement, the case often turns on reconstructing the parties’ agreement from emails, texts, invoices, payments, photographs, and other evidence.
