Review Signature Block Validity

Signature Block Validity Review

When to use this

Use this skill as a pre-execution checklist before a contract is signed, or as a post-execution audit to confirm a signed agreement is legally binding. Invalid execution is a surprisingly common source of disputes — a contract signed by an unauthorized person, missing witnesses, or with an incorrect entity name may be void or voidable.

Triggers:

• Before sending a contract for execution — confirm the signature block is correctly structured
• Before relying on a counterparty's signed document — verify their execution was valid
• M&A due diligence — confirm that material contracts were validly executed
• Enforcement proceedings — confirm that the contract being enforced was properly signed

Inputs

Review Checklist

Check 1 — Signatory Authority

The person signing must have authority to bind the entity. Authority flows from:

1. Statutory authority: directors, managing directors, CEOs, and similarly named officers typically have implied authority under corporate law to bind the company for commercial contracts
2. Board resolution / corporate authorization: for significant contracts (value threshold varies by jurisdiction), a board resolution authorizing the specific agreement is needed
3. Power of Attorney (POA): if signing by proxy — verify the POA: (a) is validly executed; (b) has not expired; (c) covers the specific act (signing this type and value of contract); (d) was issued in the correct form for the jurisdiction

Documents to request if authority is not obvious:

• Commercial Registration (CR) extract showing officers/directors and their authority
• Board resolution or written unanimous consent authorizing the agreement
• Delegation matrix if the signatory is below C-suite level
• POA document (if signing under power of attorney) with notarization/apostille as required

Flag: if the signatory is identified as "Authorized Signatory" but no authorization document is attached — the counterparty may challenge enforceability if a dispute arises.

Check 2 — Capacity / Title Accuracy

The capacity block (title printed below the signature line) must accurately describe the signatory's role:

• Correct: "Director", "Chief Executive Officer", "Managing Director", "Authorized Signatory (per POA dated [X])"
• Flag: vague descriptions such as "Representative" or "Agent" without specification of the authority basis
• For POA signatories: capacity block should read: "Attorney-in-Fact pursuant to Power of Attorney dated [date], notarized by [notary], reference [number]"

Check 3 — Entity Name Accuracy

The entity name in the signature block must match the Commercial Registration (CR) / equivalent registration document exactly, including:

• Exact legal name (not a trade name / DBA)
• Entity type suffix (LLC, PJSC, BSC, SPC, SAL, SAE, GmbH, Ltd., etc.)
• Arabic version where required (many MENA jurisdictions require the Arabic registered name)

MENA-specific:

• UAE: the Arabic name must match exactly as it appears on the CR issued by the Department of Economic Development (DED) or the relevant free-zone authority (DIFC Registrar, ADGM Registration Authority)
• KSA: Arabic entity name is legally controlling; English transliteration is for convenience only
• Lebanon: SAL (Société Anonyme Libanaise) or SARL must be accurately described; Ministry of Finance registration number may be included
• Egypt: SAE (Société Anonyme Égyptienne) registration with GAFI should match

Flag: any discrepancy between the contract entity name and the CR — even minor differences (dropped "LLC", different transliteration) can create enforceability arguments.

Check 4 — Witness Requirements

Some jurisdictions require witnesses to contracts or to specific types of clauses:

Flag: witness block absent where required; witness is a party to the contract (generally disqualifies the witness in many jurisdictions); witness description (name, ID, contact) missing.

Check 5 — Date Consistency

Execution issues:

• All parties should have the same execution date, or if different dates, the agreement should specify which party's date is the "Effective Date"
• Backdating: a contract dated earlier than its actual execution date is problematic — may be void for fraud; may affect limitation periods; may conflict with contemporaneous documents
• Future dating: acceptable if the agreement is intended to take effect on a future date, but the execution date should still reflect when signatures were applied

Gregorian / Hijri date handling:

• In Saudi Arabia, some official documents use Hijri dates; for commercial contracts, both Gregorian and Hijri dates are commonly included
• Verify that any date conversion is accurate — calendar conversion errors create ambiguity about when obligations commenced

Check 6 — Counterparts Clause

If parties are signing in different locations (common in cross-border deals), the contract should contain a counterparts clause:

• "This Agreement may be executed in counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument"
• Without this clause, a party might argue that only a single physical document with all signatures is binding
• In PDF/e-signature scenarios: add that electronic counterparts are valid (unless e-signature is not accepted — see Check 9)

Check 7 — Cross-Border Authentication (Apostille / Legalization)

When a contract executed in one country needs to be used or enforced in another:

Flag: cross-border contracts where the authentication chain is incomplete — the document may be inadmissible in the foreign jurisdiction's courts.

Check 8 — Electronic Signature Validity

E-signatures are accepted in most jurisdictions but with different conditions:

Flag: e-signature used for a category of document that requires wet ink; e-signature platform used is not certified to the required trust level (e.g., QES required but only Advanced Electronic Signature obtained).

Check 9 — Common Seal

Older requirements:

• Lebanon (older SAL companies): some articles of incorporation require the company seal to be affixed
• KSA: company seal (ختم) is customary and provides practical enforceability signal; not always strictly legally required but strongly recommended
• UK pre-2006: common seal requirement largely abolished by Companies Act 2006; now optional
• UAE: company seal still commonly affixed as a practical matter, though not strictly required for all contract types

Check 10 — Page Initialing

• UAE and many MENA practice: initialing each page by both parties' signatories is customary but not a strict legal requirement for validity
• However: initialing provides strong evidence that the pages initialed were part of the agreement as at the date of signing — important protection against substitution of pages
• Check: if a contract is long (over 10 pages) and is not initialed page by page, a party might argue that pages were substituted after execution. Recommend initialing in any contested or high-value deal.

Common Mistakes

• Relying on a title like "CEO" without a board resolution for contracts above the officer's standard authority threshold
• Accepting an English-only entity name for a MENA counterparty whose CR is in Arabic — the English name may not be a registered name at all
• Failing to check that a POA covers the specific type of transaction being signed (a general commercial POA may not cover real estate or IP assignments)
• Ignoring Hijri/Gregorian date conversion errors — they can cause genuine ambiguity about notice periods and limitation start dates
