diligence

Quick answer

Diligence usually means exercising reasonable care when acting under a legal duty. In contracts, it dictates how carefully you must perform obligations or vet partners. Before signing, check whether your required standard is ordinary, extraordinary, or heightened.

Definitions

What is diligence?

Legal Definition

Diligence describes the level of care a reasonable person must exercise when performing duties or making decisions under the law. This standard creates an obligation, compelling parties to act prudently rather than carelessly in their contractual dealings or during litigation proceedings. The specific required diligence often hinges on whether the duty is defined as ordinary, extraordinary, or heightened.

Plain-English Translation

Diligence means doing your homework before you sign something important. It's like checking that permission slip signature twice to make sure it’s valid and correct.

Contract relevance

Why diligence matters in contracts

Failing to meet this required level of effort can lead directly to breach of contract or liability for damages, placing the risk squarely on the negligent party.

Document context

Where diligence appears in documents

Document type	Section	Why it matters
Contract Agreement	Representations and Warranties section	Defines the baseline level of care owed by each party to the other.
Litigation Pleadings	Discovery requests/Interrogatories	Establishes what a reasonable person in your position should have known or investigated.
Statute/Regulation	Compliance requirements (e.g., SEC filing)	Sets out mandatory minimum standards for professional conduct or regulatory adherence.

Contract language

Common contract wording

Contract wording	Plain-English meaning	What to check
Exercise commercially reasonable diligence	Act with the care a smart business person would under similar circumstances	Ensure your definition matches industry norms.
Due diligence (or 'due care')	Thorough investigation or prudent action taken before committing	Confirm what specific tasks constitute this required investigation.
With all due diligence	With the requisite level of good faith and diligence	Verify if "good faith" alone is sufficient, or if a higher standard applies.

Red flags

Red flags to watch for

Risky wording pattern	Why it may matter	What to check
Diligence as determined by 'the parties'	This leaves interpretation open to argument later on regarding what was reasonable.	Demand objective criteria (e.g., industry standard) be added.
Diligence subject only to 'best efforts'	Best efforts can sometimes mean trying hard, even if it fails; check for a higher floor.	Ensure the contract requires more than just effort; require measurable results too.
Diligence without qualification	This is too broad; does it mean ordinary diligence or something higher?	Pin down whether the standard is 'ordinary' or 'extraordinary'.
Diligence to avoid any and all claims	This is an impossibly high bar, often leading to disputes over what was truly avoidable.	Check if this language should be modified to "reasonable efforts to avoid" such claims.

Wording examples

Clearer wording examples

Vague wording

Ordinary diligence

Clearer wording

The level of care expected of a competent person in your field; the baseline standard.

Vague wording

Extraordinary diligence

Clearer wording

A higher, more intensive standard required by special circumstances (e.g., high-stakes mergers); requires extra scrutiny and resources.

Note: “clearer” means easier to read — not legally reviewed or guaranteed safe.

Pre-signature checklist

What to check before signing

Is the required standard 'Ordinary' or 'Extraordinary'?

Does it specify which industry standard applies?

Are there exceptions to the diligence requirement?

What is the timeframe for performing this due diligence?

Does it mandate specific actions (e.g., hiring a lawyer, running credit checks)?

Is the duty mutual (both parties) or unilateral (only one party)?

If breached, what remedy applies (damages, termination, etc.)?

Party impact

How diligence affects each party

Party	What this party should check

Buyer	Must demonstrate that their investigation met the standard of care required by the contract terms.
Service Provider	Needs to show their performance matched the agreed-upon level of professional diligence.
Borrower	Should ensure their financial statements were prepared with adequate diligence.

Comparison

diligence vs similar terms

Related term	Plain meaning	Main difference from diligence

Negligence	Failure to exercise reasonable care	Diligence sets the contractual care standard, whereas negligence is a tort

Missing or vague

If diligence is missing or vague

If you fail to define what diligence means, a dispute will arise over whether your actions were merely careless or outright negligent. The court must then guess what a reasonable person in your specific shoes would do. This ambiguity often leads to arguments over whether ordinary care was sufficient, or if the situation demanded extraordinary attention.

Document context

How diligence shows up in legal documents

What is it?

It functions primarily as a standard of care doctrine governing contractual performance obligations and the assessment of negligence in tort claims.

Why does it matter?

Failing to meet this required level of effort can lead directly to breach of contract or liability for damages, placing the risk squarely on the negligent party.

When does it matter?

The requirement triggers when a specific action is mandated by a contract (like due diligence before closing) or upon discovery that a potential claim exists in litigation.

Where is it usually seen?

You see this standard frequently referenced in UCC § 2-301 for sales contracts and in requirements stipulated within loan covenants and merger agreements.

Who is affected?

A borrower must exercise diligence when securing financing, while a tenant must show diligence regarding property maintenance to avoid eviction proceedings.

How does it work?

First, the party assesses what an ordinary person would do in that situation. Then, they must meet or exceed that benchmark through reasonable investigation and action. This process prevents mere guesswork from qualifying as sufficient performance.
