Contract LawLegal glossary term
Quick answer
What does sole mean?
Sole usually means exclusive or singular authority. In contracts, it matters because it dictates who holds primary rights, such as sole responsibility for defects or sole right to approve changes. Before signing, check if the exclusivity is limited (e.g., 'sole remedy') or absolute.
Definitions
What is sole?
Legal Definition
Sole describes an exclusive right, duty, or status held by one party over a matter. When something is designated as sole, it means no other competing party possesses that identical claim or authority concurrently. This exclusivity often dictates who bears the primary liability or receives the final benefit under the agreement.
Plain-English Translation
If you have the sole permission slip for recess, only you can send your friend out to play tag. That means everyone else has to wait until you give them a pass too.
Term context
How sole shows up in legal documents
Why does it matter?
Misapplying the term can cause another party's claim to become subordinate, resulting in lost recovery at trial. The risk primarily falls upon the party asserting the non-sole interest.
When does it matter?
The concept triggers when a contract specifies that one entity holds sole responsibility for delivering goods by a certain date. It remains operative until the scope is explicitly modified or terminated.
Where is it usually seen?
You see this term frequently in partnership agreements, service level agreements (SLAs), and title declarations under real property deeds.
Who is affected?
The indemnitor might hold sole liability for third-party claims, meaning they pay everything. Conversely, the sole licensee gains the exclusive right to market a product within a defined territory.
How does it work?
First, the agreement must clearly identify the subject matter (e.g., 'sole rights to distribution'). Then, it must explicitly exclude or limit all other potential holders. Finally, this designation establishes that any concurrent claim is secondary or derivative.

Document context
Where sole appears in documents
| Document type | Section | Why it matters |
|---|---|---|
| Service Agreement Scope of Work section Defines who has the final say on project direction. | Indemnification Clause Indemnifying Party language Determines which party assumes sole financial risk for a specific claim. | If one side is designated as 'sole responsible,' they bear the entire burden when things go wrong. |
| Purchase Order Delivery Terms Specifies that only one vendor can supply a specific component to your company. | Warranties Sole Warranty Provider Confirms that no other third party offers an equal or better guarantee on the goods. | This prevents you from having competing claims against multiple sellers for the same defect. |
| Lease Agreement Use Rights Grants the tenant sole permission to operate a specific type of business on the property. | Covenants and Conditions Sole Right of Entry Means only that one party has the unrestricted right to access the premises at any time. | It limits other parties' ability to interfere with those rights without permission. |
| Contract wording example 'Sole Discretion of Seller' The seller gets the final word on decisions like pricing or timing. Check if this discretion is truly unlimited or conditional. | Payment Schedule 'Sole Recourse to Client' If something fails, you only have one place (the client) you can sue for recovery. Verify that there isn't a secondary path to resolution. | It locks down the decision-making power in one party’s favor. |
| Contract wording example 'Sole and Exclusive License' You get the only right to use the software within a specific geographic area. Ensure this doesn't unintentionally cover rights you intended to share later. | Governing Law/Jurisdiction 'Sole Forum for Dispute Resolution' All disagreements must be settled in that one specified court or arbitration body. Confirm the location is convenient for your operations. | It prevents disputes from getting tangled up across multiple jurisdictions. |
| Risky wording pattern 'Solely responsible for all damages' This sounds strong but doesn't specify *what* kind of damages (consequential? direct?). Clarify if the liability is limited to only direct costs or everything else too. | Indemnification Clause 'Sole obligation hereunder' This phrase is often used without context. Does it mean sole obligation under the entire contract, or just one clause? Pinpoint exactly which obligations are being made singular. | It can be a backdoor way to let other minor parties off the hook while concentrating risk on you. |
| Risky wording pattern 'Sole right to terminate upon written notice' This is good, but what if there are *other* rights? Does it exclude termination for convenience? Check for carve-outs; does the contract allow other parties a right of first refusal? | Termination Clause 'Sole option to extend term' Ensure this doesn't override an automatic renewal clause that affects both sides equally. Look for reciprocal language. | It creates imbalance; the other party might have a right they can't easily exercise. |
| Risky wording pattern 'Sole provider of services required' This sounds like an obligation, but does it mean you *must* use them, or that only they *can* provide the service? Clarify if this is a mandatory requirement for the client. | Service Level Agreement (SLA) 'Sole acceptance criteria' If the acceptance is based on one metric, but another party can argue against it, you have an issue. Verify that all necessary performance standards are covered by the sole criterion. | It restricts flexibility; if that single standard fails, your options might be severely limited. |
Contract language
Common contract wording
| Contract wording | Plain-English meaning | What to check |
|---|---|---|
| 'Sole discretion' The final decision rests entirely with one party. Check the scope: Is it unilateral or contingent on certain conditions? | Only that person/company gets to make the call. | If this power can be overridden by a majority vote later. |
| 'Sole liability for breach' One party assumes all financial responsibility if the contract is broken. Determine what kinds of losses are included under that liability (e.g., lost profit, cleanup costs). | One side takes the full hit financially. | If the other party has any residual or partial liability. |
| 'Sole right to audit' Only one specific entity can examine your books or records. Confirm that this auditing power isn't subject to limitations (like needing 30 days notice). | Only one party gets the key to look inside. | If there are defined triggers for when that audit right can be exercised. |
Red flags
Red flags to watch for
'Solely and exclusively authorized' This sounds definitive but often lacks boundaries. Does it cover every aspect of the relationship? Look for qualifiers like 'except as otherwise agreed.'
It can be used to prevent future negotiated exceptions or shared rights.
What to check: If this exclusivity applies to *all* past actions, present obligations, and future developments.
'Sole remedy available' This is common but dangerous. It means if the primary fix fails, you might have no other legal recourse. Scrutinize what happens when the 'sole' remedy proves insufficient or impossible to execute.
It caps your potential recovery at whatever that single defined remedy is worth.
What to check: If there are any secondary remedies mentioned (e.g., 'or other equitable relief').
'Sole decision maker regarding pricing' This locks the power to set prices solely in one party’s court. Does this include *cost* setting? Ensure that cost calculations aren't subject to challenge by the other side.
If the sole decider miscalculates costs, you are stuck with an unfair price without a mechanism to dispute it easily.
What to check: If there is a required review period before that decision becomes final and unchallengeable.
'Sole provider' If this word appears without defining *which* service or product, it’s too broad. Define the subject matter precisely to avoid ambiguity later on.
It allows a party to claim exclusivity over things you thought were shared resources.
What to check: If this term is linked to a specific Deliverable ID or scope item number.
'Sole right of inspection' This doesn't say *when* that inspection can happen. Is it 24/7, or only during business hours? Specify the timeframe and required notice period for exercising that sole right.
An unchecked sole right can lead to constant interruptions of your normal operations.
What to check: If there is a mandatory advance notification window (e.g., 5 business days).

Pre-signature checklist
What to check before signing
1
Is the exclusivity absolute or limited (e.g., 'sole remedy' vs. 'sole right')?
2
What specific action triggers the sole right/duty being exercised?
3
Does the contract specify *how* the sole party must exercise its power (e.g., in writing)?
4
Are there any carve-outs or exceptions to this exclusivity clause?
5
If it's a financial obligation, is the scope of that liability clearly defined?
6
Is the term reciprocal? Does the other side have equivalent singular powers elsewhere?
7
Does the language restrict the sole party's ability to delegate their rights/duties?
Party impact
How sole affects each party
| Party | What this party should check |
|---|---|
| Buyer Should check if they are granting too much exclusivity in decision-making (e.g., price approval). | Ensure the seller cannot unilaterally change core specifications without a Buyer veto. |
| Seller Should ensure that their granted sole rights are broad enough to cover all potential risks (e.g., intellectual property infringement). | Verify they aren't stuck with a narrow scope of liability. |
| Service Provider Must confirm that their sole duty isn't contingent on conditions they cannot control (e.g., 'solely responsible, provided the client delivers raw materials on time'). | Look for qualifying language to limit their own singular accountability. |
Comparison
sole vs similar terms
| Related term | Plain meaning | Main difference from sole |
|---|---|---|
| Exclusive Means only one party has the right, but sometimes others have a limited right (e.g., royalty payment). | Singular control or ownership. | Sole implies absolute singularity; Exclusive might allow for minor shared rights. |
| Primary Means the party holds the main, leading responsibility or right. | First in line or most important. | Primary suggests a hierarchy among several; Sole means no one else is even close to being primary. |
| Joint Means two or more parties share the right or duty equally. | Shared ownership or responsibility. | Sole is singular; Joint is plural and shared among the named parties. |
Missing or vague
If sole is missing or vague
If 'sole' lacks context, disputes often erupt over who pays when something breaks.
For example, if both parties are technically responsible for a late delivery, but neither has sole liability defined, they might argue about apportionment of blame or cost recovery.
This vagueness paralyzes the dispute resolution process because you cannot definitively point to one party as the primary wrongdoer or beneficiary.
It leaves open the possibility that an unmentioned third party could step in and claim a right alongside the two main parties.
