Dutch Powers of Attorney in Cross-Border Transactions: Authority, Legalisation and Closing Risk

Why a foreign power of attorney can become the last unresolved item before a Dutch closing

A power of attorney in a Dutch transaction is not merely a signature page. It must establish that the foreign party validly authorised the signatory and that the attorney may execute the specific Dutch document on its behalf.

That distinction is particularly important when a foreign buyer, seller or investor signs a Dutch notarial deed. The SPA may already have been signed electronically, all commercial points may be resolved and the funds may be ready. Closing can still be delayed if the notarial power of attorney is too narrow, signed by the wrong person or lacks the required notarisation, legalisation or apostille.

In my work alongside international counsel, powers of attorney are best treated as an authority workstream rather than a final closing formality. The relevant documents should be prepared early, matched to the transaction and cleared with the Dutch civil-law notary before originals are sent across jurisdictions.

The wider execution process is covered in Dutch Notarial Mechanics in Cross-Border M&A and the Cross-Border Deal Checklist for Dutch BV Transactions.

Contractual signing and notarial execution are different

International deal teams often sign the SPA through electronic signatures or signature pages exchanged by email.

The Dutch notarial deed is a separate legal instrument.

Dutch law requires a notarial deed for the issuance or transfer of Dutch BV shares. The parties may appear through attorneys, but the Dutch notary must be satisfied that the power of attorney is valid, sufficiently specific and granted by an authorised person.

A signature process accepted for the SPA does not therefore determine what is sufficient for the notarial deed.

The same individual may sign both documents, but the authority analysis and formal requirements can differ. This is why the notarial power of attorney should not simply be copied from the SPA signature block.

Start with the authority chain

The first question is not who is available to sign. It is who has authority to bind the foreign entity. That authority may follow from:

• the entity’s constitutional documents;
• applicable corporate law;
• board or shareholder resolutions;
• an incumbency certificate or corporate extract;
• an existing signing mandate; or
• a separate power of attorney.

A corporate resolution and a power of attorney perform different functions.

The resolution records that the entity has approved the transaction and authorises identified persons to take the required steps. The power of attorney allows another person—often an employee of the Dutch notary—to execute the notarial deed in the entity’s name.

Under Dutch law, a power of attorney is the authority granted by one person to another to perform legal acts in the principal’s name.

The Dutch notary must therefore be able to follow the chain from the foreign entity, through its valid corporate approval, to the individual granting the notarial power of attorney.

A signature by a senior executive is not necessarily sufficient if that executive’s authority cannot be evidenced.

The power of attorney must match the transaction

A generic authority “to execute all documents relating to the transaction” may appear commercially broad but still be unsuitable for the Dutch notarial deed.

The power of attorney should identify the relevant party, Dutch company, transaction and legal action. Depending on the deal, it may need to authorise:

• the purchase or transfer of specified shares;
• execution of the notarial deed;
• payment or acknowledgement of the purchase price;
• amendments needed to finalise the deed;
• receipt of notices or declarations;
• execution of related corporate documents; and
• sub-delegation to employees of the notary.

The scope should be broad enough to accommodate non-material changes to the deed but not so broad that the foreign party cannot determine which legal act it has authorised.

This balance becomes important where the deed is still being negotiated when the power of attorney is signed.

If the final deed materially changes the number or class of shares, the parties, the consideration or another central term, a new approval or power of attorney may be required. The closing team should not assume that the notary can solve a substantive authority gap through drafting.

Notarisation, legalisation and apostille are separate questions

Notarisation confirms or authenticates the signature in accordance with the procedure used in the relevant jurisdiction. Legalisation or an apostille allows that authenticated document to be used in another country.

Whether a foreign document requires an apostille depends on the type of document and the country in which it was issued. For documents originating in the United States and intended for use in the Netherlands, the Dutch government states that legalisation by apostille is generally required.

The precise closing requirement should still be confirmed with the Dutch notary.

An apostille does not repair a defective power of attorney. It does not prove that the transaction was validly approved or that the signatory had sufficient corporate authority. It authenticates the relevant signature or public document for international use.

The correct sequence is therefore:

1. confirm who has corporate authority;
2. obtain the required corporate approval;
3. sign the correct form of power of attorney;
4. notarise the signature where required; and
5. obtain an apostille or other legalisation where required.

Reversing that sequence can result in a formally authenticated document that still does not establish valid transaction authority.

The notary’s requirements should be checked before signing

Different transactions and jurisdictions create different document requirements.

A US corporation may need to provide its constitutional documents, board resolutions, evidence of good standing and an incumbency or authority certificate. A private equity buyer may also need to explain the authority chain through its fund, general partner, manager and acquisition vehicle.

The notary may require originals, certified copies or recently issued corporate extracts. KYC and ultimate beneficial owner information may be needed in parallel.

The practical mistake is sending the power of attorney for signature before the notary has reviewed:

• the identity of the signatory;
• the corporate approval;
• the form of signature authentication;
• the required apostille or legalisation;
• the language of the document; and
• whether an original must be delivered before closing.

Foreign documents that are not in Dutch, English, French or German may also require translation for use in the Netherlands.

A five-minute confirmation before signing can prevent several days of re-execution and international courier delays.

Changes to the deal can invalidate the execution plan

Powers of attorney are often prepared while the SPA, funds flow and notarial deed are still being negotiated.

That is commercially understandable, but it creates document-control risk.

The transaction team should recheck the authority documents when:

• the acquisition vehicle changes;
• another seller or investor joins;
• the number or class of shares changes;
• the purchase price mechanism changes materially;
• the notarial deed is combined with a share issuance or amendment of articles;
• the signing or closing structure changes; or
• a different person will grant or use the power of attorney.

The most difficult closing problems are often not caused by the original document. They arise because the transaction changed after the document was signed.

One person should therefore own the authority matrix and confirm before closing that each entity, signatory, approval and power of attorney still corresponds to the final transaction.

The SPA, closing agenda and notarial deed must align

The power of attorney should not be reviewed in isolation.

The SPA may state who transfers the shares and when title passes. The closing agenda sets out the sequence. The resolutions approve the transaction. The power of attorney authorises execution. The notarial deed effects the legal transfer.

If those documents identify different entities, signatories, share numbers or conditions, the closing process becomes uncertain.

The Dutch workstream should therefore reconcile:

• the parties in the SPA;
• the registered shareholders;
• the corporate approvals;
• the powers of attorney;
• the funds flow;
• the notarial deed; and
• the post-closing shareholder register and filings.

This reconciliation is part of legal deal execution. It should not be delegated entirely to signature-page management.

Common execution mistakes

Three mistakes recur in cross-border closings.

The first is assuming that the person who signed the SPA can automatically sign the notarial power of attorney.

The second is obtaining an apostille before confirming that the underlying authority and document scope are correct.

The third is waiting for the SPA to be fully agreed before beginning the authority and legalisation process.

The better approach is to prepare the notarial authority package once the structure, parties and principal terms are sufficiently stable. The final deed can continue to develop while the corporate, KYC and authentication workstreams move forward.

Conclusion

A foreign power of attorney becomes a closing risk when it is treated as a routine signature document.

The Dutch notarial workstream requires a complete authority chain: valid corporate approval, an authorised signatory, a transaction-specific power of attorney and the correct notarisation, legalisation or apostille.

International deal teams should agree these requirements with Dutch counsel and the civil-law notary before the final closing week.

The commercial documents determine what the parties agreed. The authority documents determine whether that agreement can actually be executed.

FAQ

Can a foreign party sign a Dutch notarial deed by power of attorney?

Yes. Foreign parties commonly grant a power of attorney allowing a representative to execute the Dutch notarial deed on their behalf.

Does every foreign power of attorney require an apostille?

No. The requirement depends on the jurisdiction, document and notary. It should be confirmed before signing.

Does an apostille prove that the signatory had corporate authority?

No. An apostille authenticates a signature or public document. The underlying corporate authority must still be established separately.

Can the same power of attorney be used for the SPA and the notarial deed?

Sometimes, but the notarial deed usually requires a specific form and scope. The requirements should be checked with the Dutch notary.

When should the power-of-attorney process start?

Once the parties, acquisition structure and principal transaction terms are sufficiently clear. It should not be postponed until all SPA drafting is complete.
