The Litigation Risk That Surfaces Between Signing And Closing: How Investment Banks Can Protect Transaction Execution

13-Nov-2026

An acquisition can be commercially agreed, legally documented and fully financed without being ready to close.

Between signing and closing, a court may issue an adverse order, a regulator may initiate proceedings or a previously undisclosed dispute may emerge. These developments can challenge the assumptions on which the buyer agreed to the transaction.

For investment banks, this period presents a distinct form of M&A execution risk. The purchase price may already be negotiated, while the buyer's ability to reconsider terms depends on the acquisition agreement.

The critical responsibility is to establish whether a litigation development changes the economics of the transaction, affects a contractual closing requirement or demands further investigation before completion.

A Rs 6,000 Crore Acquisition Facing an Unexpected Court Order

Consider a hypothetical acquisition of an industrial manufacturing business at an enterprise value of Rs 6,000 crore.

The target generates Rs 750 crore in normalised EBITDA, supporting an acquisition multiple of 8.0x.

The parties sign a share purchase agreement, with closing expected in 75 days, subject to agreed conditions.

On day 42, a court issues an interim order affecting operations at a facility contributing Rs 120 crore in annual EBITDA.

The seller maintains that the order is temporary and commercially manageable. The buyer questions whether the original valuation remains supportable.

The investment bank must assess the potential impact without assuming that the order permanently destroys value or automatically permits termination.

Distinguish Newly Discovered Litigation From New Developments

Not every litigation issue identified after signing represents a new legal event.

A proceeding may have existed before signing but remained absent from the seller's disclosures. Alternatively, a previously disclosed case may have developed materially after execution of the agreement.

These situations raise different contractual questions.

A historical omission may require examination of representations, disclosure schedules and the information provided during diligence.

A genuinely new proceeding may engage interim operating covenants, notification obligations or negotiated closing protections.

The first task is therefore to reconstruct the timeline using verified court records, transaction documents and relevant correspondence.

Establish a Signing-to-Closing Litigation Control Framework

Risk Event

Immediate Assessment

Potential Transaction Response

Newly discovered historical proceeding

Was it covered by existing disclosures and warranties?

Review representations and contractual remedies

Adverse judicial order

Does it affect operations or financial forecasts?

Reassess closing readiness and valuation

New regulatory proceeding

Are approvals or operating permissions affected?

Obtain specialist legal assessment

Material settlement

Does it create a significant cash obligation?

Review permitted conduct and pricing treatment

Critical asset dispute

Could the buyer lose access to the asset?

Examine closing conditions and risk allocation

Case status change

Is the change substantive or procedural?

Update the diligence record

The framework should support escalation, not substitute for legal interpretation of the acquisition agreement.

Quantify the Impact on Enterprise Value

Return to the hypothetical facility contributing Rs 120 crore in annual EBITDA.

If the court order permanently eliminates that contribution, applying the acquisition multiple of 8.0x produces an illustrative enterprise value sensitivity of Rs 960 crore.

However, that calculation represents a severe downside assumption, not a forecast.

A three-month disruption could have substantially different consequences if production can be restored and customers retained.

Investment banks should model temporary disruption, partial recovery and permanent impairment separately.

They must also reconcile the scenarios with existing forecasts to avoid counting the same operating loss twice.

Examine Closing Conditions Before Recommending Action

A material litigation development does not automatically entitle the buyer to renegotiate or terminate an acquisition.

The relevant rights depend on the transaction agreement and applicable law.

Counsel should examine the negotiated conditions precedent, representations, interim covenants, notification requirements and any material adverse change provisions.

The precise wording matters.

An event that materially affects valuation may not satisfy the contractual standard required to prevent closing.

Investment banks should therefore separate the economic assessment from the legal assessment of available remedies.

Evaluate Whether Deal Protections Remain Sufficient

A newly identified risk may require additional protection even where the transaction remains commercially attractive.

Possible responses include a specific indemnity, funded escrow, agreed remediation action or revised closing condition.

However, the buyer's ability to secure these protections depends on contractual rights and negotiation.

A seller indemnity may offer limited protection where recovery is uncertain.

An escrow may improve recovery prospects but introduce disagreement over the amount and release period.

For risks threatening fundamental operating assets, additional contractual compensation may not adequately protect the acquisition thesis.

Maintain a Pre-Closing Litigation Exception Register

Transaction teams should maintain a controlled record of material developments after signing.

Each exception should include the relevant party, case identifier, verified source, date of development, legal assessment and potential financial impact.

The register should also identify the applicable contractual provision, responsible adviser and required decision.

This helps prevent significant findings from becoming fragmented across legal correspondence, management updates and financial models.

The investment committee should receive unresolved exceptions with clear recommendations rather than an undifferentiated list of court cases.

The Financial Cost of Delayed Litigation Escalation

Consider a hypothetical transaction requiring 200 additional professional hours to investigate a late-stage proceeding.

At a blended internal cost of Rs 5,000 per hour, the additional advisory capacity amounts to Rs 10 lakh.

That figure excludes external legal expenses and any consequences of delayed completion.

The more consequential risk may be financing uncertainty, operational deterioration or the loss of an agreed commercial timetable.

Early escalation allows the transaction team to assess these consequences while practical options remain available.

The objective is not to eliminate all uncertainty but to prevent unresolved legal developments from becoming avoidable execution failures.

How LegitQuest LIBIL® Supports Pre-Closing Litigation Due Diligence

LegitQuest's LIBIL® Litigation Check supports litigation discovery and structured reporting for companies, directors and other relevant parties.

Its capabilities include AI-assisted identity resolution, case categorisation, duplicate identification and source-linked litigation information.

For investment banks, these functions can support refreshed litigation screening before closing and help identify proceedings requiring additional verification.

Detailed Litigation Check Reports and Lawyer Verified Litigation Check Reports offer additional review options for significant findings.

LIBIL® supports litigation discovery and verification. It does not independently determine contractual remedies, establish material adverse change or recommend transaction termination.

Those decisions require transaction-specific legal and financial advice.

Make Litigation Verification Part of Closing Readiness

Before closing, investment banks should reconcile significant litigation developments against the signed agreement and the latest financial model.

The closing review should confirm whether material findings have been verified, contractual notifications addressed and necessary legal assessments completed.

Outstanding exceptions should have documented owners and agreed treatment.

This process helps ensure that the investment committee understands the risk position at completion, rather than relying exclusively on diligence performed before signing.

Conclusion

The signing-to-closing period is not simply an administrative interval between commercial agreement and ownership transfer.

It is a period during which litigation developments can change operating assumptions, financial exposure and contractual execution requirements.

For investment banks, effective M&A due diligence must continue through closing, combining verified legal information with valuation analysis and disciplined contractual review.

The strongest transaction process is one that identifies consequential changes early, assesses them proportionately and ensures that closing decisions reflect the risks the buyer is actually assuming.

Frequently Asked Questions

Why should litigation due diligence continue after signing?

New proceedings and material developments in existing cases may affect valuation assumptions, contractual obligations and closing readiness.

Can a buyer terminate an acquisition because of new litigation?

Not automatically. The buyer's rights depend on the acquisition agreement, applicable law and the facts of the proceeding.

How can litigation affect deal valuation before closing?

Litigation may change expected EBITDA, cash flows, capital expenditure, asset availability or the probability of completing the transaction.

What should investment banks review before acquisition closing?

They should reconcile material litigation developments, financial implications, contractual protections and unresolved closing conditions.
