State by State Written Contract Laws Map

The following question pops up frequently on construction projects (and just as often in our Expert Center!) all the time: “Can I file a lien even though I don’t have a written contract?” And, as with most of the questions we get about mechanics lien rights, the answer is: it depends.

Handshakes and verbal agreements are common in the construction industry, but finding answers on how lien rights apply to contracts that are not written and signed can be a challenge. We’ve collected the relevant information from all 50 states’ mechanic’s lien statutes and compiled it here to make this question easier to answer.

The answer depends on your state: Different states have different contracting requirements

Mechanics lien laws vary widely from one state to the next, so it’s necessary to understand your state’s lien laws in order to secure your lien rights. When it comes to whether construction contracts must be in writing or not to qualify for lien rights, some states strictly require a signed contract, while others are more flexible.

States typically fall into one of the following 4 categories when it comes to improvement contracts and lien rights:

  • States where written contracts are explicitly required to secure lien rights
  • States where written contracts are not required to secure lien rights
  • States with rules on contracts based on the amount or type of work
  • States that don’t specify types of acceptable contracts

The maps and discussion below provide a general guide as to whether a contract type affects mechanics lien rights for contractors, suppliers, and other construction parties.

1. States where the lien law explicitly requires a written contract

In these states, a written contract between the party providing work and the hiring party is an absolute necessity in order to secure lien rights. Contractors, suppliers, and other parties can only claim a mechanics lien for funds mentioned in written contracts. If it’s not in writing…then you don’t have lien rights! Simple as that. Here are the states that require a written contract to file a lien:

*In Texas, written contracts are required for all claimants in order to claim a lien against residential homestead projects, and architects, engineers, surveyors, and landscapers need to have written contracts on all project types.

2. States where the lien law doesn’t require a written contract

States where written contracts are not required map

In these states, contractors and suppliers are generally allowed to file a lien even if they don’t have a written contract.  In other words, the claimant could be working off on an oral or verbal agreement, and yet still have the ability to file a lien claim!

These statutes typically use language like “for the specific contract or agreed upon change” (New Mexico) and “contract means an agreement that provides for all or part of a work or improvement” (California) to describe contracts, and do not explicitly require that contracts must be written.

However, as explored with a situation in Ohio, not having a written contract can really clutter issues and create a sticky mechanics lien dispute.

These states typically permit parties with verbal, oral, or even implied contracts to claim lien rights. Be sure you familiarize yourself with the specific rules in the state you’re working in. Click on your state in the lists below to view each mechanics lien statute in full.

Even though these states may permit project participants to secure lien rights and claim a mechanics lien even without a written contract, it is generally best practice to have a signed written contract for work provided. Documentation is crucial in the construction industry, and many times, what a party has documented is more important than what actually happened!

3. States where written contracts are required sometimes, depending on the amount or type of work

States with exceptions in written or oral improvement contracts map

There are two states — Colorado and Indiana — that require written contracts sometimes, depending on the value of the work being performed, or the type of work being performed. Contract requirements in these states have more to do with the type of work being provided or the type of project, rather than with the actual form of the contract itself.

Colorado:  Colorado’s lien statute is relatively straightforward, and the written contract requirement is based on the contract price. The relevant part of the statute states that if the amount to be paid exceeds $500, the contract must be in writing in order to claim a mechanics lien. Any agreement for work or materials below this amount is not required to be in writing to file a valid mechanics lien claim.

Indiana Indiana’s approach to this issue is a bit different, as they rely on who the property owner is. If the property is owned by a public utility, municipality, joint agency, rural electric membership corporation, rural telephone cooperative corporation, or not-for-profit utility, a written contract is necessary to secure lien rights. Also, a copy of the contract has to be filed and recorded in the recorder’s office within five days of the execution of the contract.

4. States where it’s not specified

Some state laws don’t make this question easy because they aren’t specific about whether or not contracts must be written in order for a contractor or supplier to file a lien. Oral contracts are typically valid so long as they adhere to the state’s rules on contracts, but companies should consult with a lawyer if they questions about a specific situation and don’t have a clearly defined written contract.

Top 3 questions about written contract requirements

It’s common for us to see this question asked on the Expert Center. Here are some example questions and answers about the “written contract” requirement in some of these states.

Subcontractors on residential projects without a contract with the owner?

This question was asked about a situation in Arizona, but the answer will apply everywhere!  Someone asked, Can a subcontractor file a lien in AZ…if he has no written contract? Can he file a lien if the single-family residence is occupied, and he has no contract with the homeowner?

This question is interesting because it presents a twist to the “written contract” discussion. The question here is really about “privity of contract,” and not whether the contract is written or verbal. This question appears to come from a homeowner who didn’t contract with a subcontractor at all. As such, the subcontractor doesn’t have a “written contract” with the owner.  In fact, the subcontractor doesn’t have any contract with the owner — neither written nor verbal!

However, presuming the subcontractor has a contract with the general contractor (or someone!) on the job, the subcontractor will have lien rights in this case.  And since this project is in Arizona, and we know Arizona doesn’t require contracts be in writing, this sub would have lien rights even if the contract was just an oral agreement.

A very similar question was asked about a Texas situation…and as we saw above, Texas does require contracts be in writing. However, presuming that the subcontractor on the project has a written contract with someone, they can still file a lien even if they don’t have a written agreement with the property owner.

See that question & answer here:  In the state of TX, can a subcontractor file a lien against an owner if there was no written or verbal agreement between the owner and the subcontractor?

What exactly is a contract?  Is a purchase order a contract?

Let’s say you are in a state — like Georgia — that requires a written contract to have lien rights. You have some stuff in writing, but is it actually a “contract?”  What exactly is a contract?

This is a common question and one that came up on our Expert Center when a material supplier asked, Do purchase orders count as a contract? To answer this question, the construction attorney went into the legal requirements to form a contract. These can be really sticky requirements, and it’s not always clear.  Ultimately, the answer concluded, a purchase order may ultimately create a contractual relationship between the parties if all the required elements are present.

So, even in states that require written contracts…something you have in writing may qualify for as the “contract,” even if it is not explicitly marked as a contract. As long as the essential requirements for a contract are met, even a string of text messages could potentially result in a binding contract.

What if extra work or changes aren’t in writing?

Another common question that arises in this “written contract” category is about changes to the work. It’s super common that changes to the contract and to the work occur throughout the course of a construction job. And with the speed of construction, these changes frequently don’t get neatly documented.  Extra work will get approved orally, or a change may be demanded without even agreement!  What happens then?  Does that need to be writing for lien rights, too?

This came up on our Ask an Expert Center with this question related to a Texas project:  Can I file a lien on extra work for which I don’t have written authorization?

The answer provided, and the general answer to provide is that if the written contract requirement is satisfied and there is a written contract in place, changes and authorized work may still be subject to a lien, even though a second contract wasn’t executed.  The changes themselves, in other words, are actually done under and within the original contract.

Conclusion

It’s always a good idea to get a written contract to ensure a smooth payment process and to minimize risk. Regardless, in several states, oral agreements (or even implied ones) are more than sufficient to secure lien rights. This article is meant to give a general overview of the requirements as a jumping-off point for those curious about whether or not it is necessary to have a written contract in order to secure mechanics lien rights.
