interfere

Contract LawLegal glossary term

Quick answer

Interfere usually means obstructing or hindering another party’s rights. In contracts, it matters because it triggers a duty to fix the disruption or pay damages. Before signing, check if the interference is permissive or intentional.

Definitions

What is interfere?

Legal Definition

Interfere describes any action that obstructs, hinders, or disrupts another party's right to use property or exercise a contractual entitlement. This interference creates an immediate legal obligation for the interfering party to remedy the disruption or compensate the injured party for losses incurred. The critical qualifier here is whether the interference was permissive (allowed) or intentional.

Plain-English Translation

Interference happens when someone messes with your stuff—like if your friend borrows your favorite toy and won't give it back. It stops you from using it as you planned, which feels like breaking a promise on the permission slip.

Contract relevance

Why interfere matters in contracts

Ignoring interference allows the injured party to sue for damages, potentially voiding their expected performance under a contract. The risk of liability falls squarely on the interfering party.

Contract language

Common contract wording

Contract wordingPlain-English meaningWhat to check
Party A shall not interfere with Party B's operations.It means Party A cannot block or hinder what Party B is doing.Look for context: Is the interference physical, legal, or operational?
Breach by Interference.A failure to perform caused by an external disruption.Confirm if the contract defines 'interference' specifically.
Non-Interference Clause.An agreement stating one party will not meddle in the other's affairs.Ensure the clause covers all types of potential interference (e.g., financial, reputational).
Permissive Interference.When a party allows another action that causes disruption.This is critical; it changes the level of fault assigned.

Red flags

Red flags to watch for

Risky wording patternWhy it may matterWhat to check
Interfere with the rights of the other party.Too vague; doesn't specify *how* or *what* right is affected.Demand specificity regarding the scope and nature of the interference.
Any action that may interfere...The use of 'may' creates ambiguity about certainty.Clarify if the interference must be actual or merely potential.
Interference without fault.This might shield a party from liability entirely.Determine if this means *no* fault or just *unintentional* fault.
Interfere upon...Poor preposition choice; it's less formal than 'with' or 'in'.Check the surrounding language to see which verb/preposition fits best.

4

Are there limitations on when the interference must occur (e.g., during performance)?

5

Is the clause mutual (both parties can interfere) or unilateral?

6

Does it distinguish between direct and indirect interference?

Comparison

interfere vs similar terms

Related termPlain meaningMain difference from interfere
BreachA failure to perform a duty; interference is often the *act* causing the breach.Interference describes the *method* of disruption; breach is the resulting contractual violation.
HindranceOften refers to slowing down progress or making performance difficult.Hindrance suggests impairment, whereas interference can mean outright blocking (stopping).
ImpairmentA more technical term suggesting damage or weakening of a right.Impairment focuses on reducing value; interference focuses on preventing exercise.

Missing or vague

If interfere is missing or vague

If the clause doesn't define 'interfere,' disputes will arise over whether minor delays constitute actionable obstruction.

Courts will then have to interpret the term based on general commercial custom, which is unpredictable for business owners.

Furthermore, without qualification (permissive vs. intentional), a party might argue they merely allowed a third party to cause trouble, thereby avoiding liability entirely.

Document context

How interfere shows up in legal documents

What is it?

This term functions primarily as a doctrine within Contract Law and Tort Law. It governs situations where a third party improperly disrupts established rights or agreements between two primary parties.

Why does it matter?

Ignoring interference allows the injured party to sue for damages, potentially voiding their expected performance under a contract. The risk of liability falls squarely on the interfering party.

When does it matter?

Interference triggers when an action occurs—for instance, when a competitor begins selling goods in your designated territory, or when a subcontractor starts work before the primary contractor formally grants permission.

Where is it usually seen?

You see this language frequently within breach of contract clauses, specifically regarding covenants running with the land, and in tort claims like 'trespass to chattels' agreements.

Who is affected?

The indemnitor risks having to pay damages if their actions interfere with another party’s rights. A tenant gains the right to sue when a neighboring property owner interferes with their quiet enjoyment of the leased space.

How does it work?

First, the injured party must prove a valid legal right existed. Then, they must demonstrate an unauthorized act occurred that actively blocked or disrupted that right. Finally, they show that this obstruction caused quantifiable harm or damage.
