Losing a company share certificate can be worrying, particularly when you are preparing to sell shares, transfer them to someone else, raise investment or complete a business acquisition. The good news is that losing a UK company share certificate does not normally mean losing the shares themselves.

A share certificate is evidence relating to the shares registered in a shareholder's name. The company's register of members is a fundamental record of who holds the shares. A lost certificate can therefore usually be dealt with by the company issuing a replacement, provided the correct procedure is followed.

For companies using the model articles for private companies limited by shares, the rules are particularly clear: where a certificate is said to be lost, stolen or destroyed, the shareholder is entitled to a replacement certificate for the same shares, subject to conditions the directors may impose concerning evidence, indemnity and a reasonable fee. This guide explains how to replace a lost share certificate in the UK, what documents you may need, what happens if the company has changed directors or shareholders, and what to do if the company itself can no longer locate its records.

What Is a Share Certificate?

A share certificate is a document issued by a company to a shareholder in respect of shares registered in that person's name. For a private company using the model articles, the certificate should identify:

• The number of shares covered
• The class of shares
• The nominal value
• Whether the shares are fully paid
• Any distinguishing numbers assigned to the shares

A certificate cannot cover shares belonging to more than one class under the model articles. For example, if you own 1,000 A Ordinary Shares and 500 B Ordinary Shares, the company may issue separate certificates because the two classes are different.

It is important to understand that a share certificate is not the same as the company's register of members. The certificate provides evidence of the shares, while the register records the company's members. That distinction becomes especially important when an old certificate has been lost but the company's underlying records remain intact.

Can You Replace a Lost Share Certificate?

Yes. In most cases, a lost UK company share certificate can be replaced. If the company uses the model articles for private companies limited by shares, Article 25 expressly provides for replacement certificates where a certificate is:

• Lost
• Stolen
• Destroyed
• Damaged
• Defaced

The shareholder is entitled to a replacement certificate for the same shares, although the directors can require appropriate evidence, an indemnity and payment of a reasonable fee. However, the precise procedure depends on the company's articles of association. Not every company has identical articles. Companies can adopt model articles or use bespoke articles, so you should check the company's actual constitution before assuming that a particular procedure applies. GOV.UK confirms that companies can use standard model articles or create their own articles.

Step-by-Step: How to Replace a Lost Share Certificate

Step 1: Confirm That You Are the Registered Shareholder

Before requesting a replacement, establish that your name appears in the company's register of members. This is particularly important if:

• The shares were inherited
• The shares were transferred to you years ago
• The company has changed ownership
• The original shareholder has died
• The certificate was issued to a previous owner
• You purchased the shares from someone else

A share certificate in your possession is useful evidence, but the company's register of members should also be checked. If the company's records are unclear, replacing the certificate may be only part of the problem. You may first need to establish who is legally registered as the shareholder.

Step 2: Check the Company's Articles of Association

The next step is to check the company's articles. This determines the company's rules for issuing and replacing certificates. For a private company using the current model articles, Article 25 allows replacement where a certificate is lost, stolen or destroyed. It also allows the directors to require evidence, an indemnity and a reasonable fee. This means there is no single compulsory replacement form used by every UK company. A company with bespoke articles may have a more detailed procedure.

Step 3: Notify the Company in Writing

Contact the company and explain that the share certificate has been lost. The request should normally identify:

• Your full name
• Company name
• Company number
• Number of shares held
• Share class
• Certificate number, if known
• Approximate date the original certificate was issued
• The fact that the original certificate is lost, stolen or destroyed
• A request for a replacement certificate

If you are a shareholder of your own company, the request can still be formally documented in the company's records. For example:

"I confirm that the share certificate issued in respect of my 10,000 Ordinary Shares has been lost and cannot be located. I request that the company issue a replacement certificate in accordance with its articles of association."

Keeping the request in writing creates a clear administrative record.

Step 4: Provide Evidence of the Lost Certificate

The directors may reasonably want evidence that the request is genuine. Under the model articles, directors can impose conditions concerning evidence before issuing a replacement certificate. Depending on the circumstances, the company may ask for:

• A signed declaration
• A statutory declaration
• Details of when and where the certificate was last seen
• A copy of the shareholder's identification
• Evidence of the shareholder's registered ownership
• Confirmation that reasonable efforts were made to locate it
• A police report where theft is alleged

Not every case requires all of these documents. A simple certificate lost during an office move may require much less evidence than a disputed certificate relating to a substantial shareholding.

Step 5: Provide an Indemnity if Requested

An indemnity is a promise to compensate the company if it suffers a loss because the original certificate later turns up and causes a problem. For example, imagine:

1. Sarah owns 20,000 shares.
2. Her certificate is lost.
3. The company issues a replacement.
4. The original certificate is later discovered.
5. Someone attempts to use the original document to create a competing claim.

An indemnity can protect the company against certain losses arising from replacing the certificate. The model articles expressly allow directors to require an indemnity as a condition of replacement. For significant shareholdings, the company may take the indemnity process more seriously and may seek professional advice on its wording.

Step 6: Pay Any Reasonable Replacement Fee

Under the model articles, directors can require payment of a reasonable fee for issuing a replacement certificate. The amount is not a universal Companies House fee. In other words, you do not normally pay Companies House to replace a company's share certificate. The certificate is issued by the company, so any replacement fee is generally dealt with between the shareholder and the company.

Step 7: Directors Approve and Issue the Replacement

Once the company's requirements have been satisfied, the directors or authorised company officers can arrange for the replacement certificate to be issued in accordance with the articles. The replacement should clearly identify the relevant shares. The company should also keep an appropriate record showing that the original certificate was reported lost and that a replacement was issued. This helps prevent confusion if the original certificate later appears.

What Should the Replacement Share Certificate Say?

The replacement certificate should accurately reflect the shareholder's existing shareholding. Under the model articles, it should specify:

• The number of shares
• The share class
• The nominal value
• Whether the shares are fully paid
• Any distinguishing numbers assigned to the shares

The model articles also require certificates to be properly executed, either using the company's common seal or in another manner permitted by the Companies Acts. The replacement should not accidentally change the shareholder's rights or create additional shares. For example, if the original certificate represented 5,000 ordinary shares, the replacement should represent those same 5,000 shares. It is not a new allotment of 5,000 shares.

Does Replacing a Certificate Create New Shares?

No. This is one of the most important points. A replacement certificate documents an existing shareholding. It does not normally create additional shares. Suppose a company has 10,000 issued shares and you own 4,000.

Your certificate is lost. The company issues you a replacement certificate for 4,000 shares. The company still has 10,000 issued shares, not 14,000. This is fundamentally different from an allotment of new shares. When a company actually issues new shares, Companies House generally needs to be notified of the allotment within one month. A replacement certificate is not an allotment.

Do You Need to Notify Companies House?

Normally, no Companies House filing is required simply because a share certificate has been lost and replaced. The replacement does not itself change:

• The number of shares
• The shareholder
• The share class
• The company's issued share capital

The important work happens within the company's own corporate records. However, if the underlying issue involves a share transfer, new allotment, change in share class or other corporate change, separate Companies House filing requirements may apply. This distinction prevents a common mistake: assuming every change involving a share certificate needs to be reported to Companies House.

What If the Company Has Lost Its Share Records Too?

This situation is more complicated. Suppose you say: "I lost my share certificate." The company checks its records and discovers that it also cannot find:

• The original register of members
• The original certificate
• Historical share transfer documents
• Allotment records
• Board minutes

At that point, the company cannot simply print a replacement certificate based on memory. The company should first reconstruct the ownership evidence as far as reasonably possible. Useful evidence may include:

• Companies House filings
• Previous confirmation statements
• Original incorporation documents
• Share allotment records
• Stock transfer forms
• Board minutes
• Shareholder agreements
• Copies of old certificates
• Accountant or solicitor records
• Acquisition or investment documents

Companies House records can help establish the company's historical share capital, but they do not necessarily contain every internal corporate document. Where ownership is disputed or the records are seriously incomplete, professional legal advice may be appropriate.

What If the Company Has Changed Directors?

A change of directors does not normally prevent a company from replacing an old certificate. The current directors are responsible for administering the company according to its articles and applicable law. For example, suppose a company was incorporated in 2018. Its original director has since resigned and a new director took over in 2025. A shareholder discovers in 2026 that their certificate is missing.

The current directors can deal with the replacement, provided they have sufficient evidence of the shareholder's entitlement and follow the company's constitutional requirements. The important issue is the company's records and the shareholder's registered position, not whether the original director is still in office.

What If the Shareholder Has Changed Their Name?

A name change can add another layer to the process. For example, a shareholder may have received a certificate under a previous surname after marriage. If the company's register still contains the old name, the company should establish whether the shareholder's registered details need updating and what evidence is appropriate.

The company should not casually issue a replacement certificate with a different name while leaving inconsistent corporate records. The replacement should match the company's updated records.

What If the Shareholder Has Died?

If the registered shareholder has died, the situation is different from an ordinary lost certificate. The shares become part of the deceased person's estate, and the personal representatives may need to deal with the shares according to the applicable succession and company law procedures.

The company should not simply issue a replacement certificate in the beneficiary's name because the beneficiary has requested one. It may first need evidence of the personal representative's authority and documentation establishing entitlement to the shares. This is particularly important where the deceased was the company's sole shareholder and director.

What If the Certificate Was Stolen?

The process is broadly similar to a lost certificate, but the company may require additional evidence. The shareholder should tell the company that the certificate was stolen rather than merely saying it is missing.

Depending on the circumstances and value of the shareholding, the company may ask for a police report or formal declaration. The purpose is to protect both the shareholder and the company against someone attempting to misuse the original certificate.

What If You Find the Original After Receiving a Replacement?

Do not continue using both certificates. Contact the company immediately and return the original certificate if requested. The company should maintain a clear record of which certificate is valid and which has been replaced or cancelled. This is particularly important if the shareholder intends to sell or transfer the shares. Having two apparently valid certificates for the same shares can create unnecessary confusion during due diligence.

What If You Need the Certificate to Sell Your Shares?

A lost certificate can become urgent when a shareholder is preparing a share transfer. For example, a buyer may request evidence of title as part of the transaction. If the certificate cannot be found, the seller should normally contact the company as early as possible rather than waiting until completion. The company may need to:

1. Confirm the shareholder's registered ownership
2. Establish that the original certificate is genuinely unavailable
3. Obtain an indemnity or other evidence
4. Issue a replacement
5. Update or prepare the relevant transfer documentation

The exact procedure depends on the company's articles and the transaction. The key lesson is simple: deal with the missing certificate before the transaction becomes time-critical.

How to Prevent Future Share Certificate Problems

Once a replacement has been issued, improve the company's record-keeping. A sensible company should maintain:

• A digital copy of every certificate
• Certificate numbers
• Dates of issue
• Details of cancellations and replacements
• The register of members
• Share allotment records
• Share transfer documents
• Board resolutions relating to share transactions

GOV.UK requires companies to maintain appropriate company and accounting records, and companies should have systems that allow important corporate information to be recreated where records are lost or destroyed. For a company with multiple shareholders or share classes, good record-keeping becomes even more important.

Frequently Asked Questions

Can I replace a lost share certificate myself?

No. The replacement should normally be issued by the company whose shares the certificate relates to. The shareholder requests the replacement and provides whatever evidence or indemnity the company's articles and directors require.

Do I need to contact Companies House if I lose my share certificate?

Usually not. Simply replacing a lost certificate does not normally change the company's share capital or ownership. Companies House notification may become relevant if the underlying transaction involves a new allotment, transfer or other reportable change.

Is a lost share certificate the same as losing my shares?

No. Losing the physical certificate does not normally mean that the underlying shares have disappeared. The company's register of members and other corporate records are important evidence of the shareholder's position.

Can a company refuse to replace a lost share certificate?

The answer depends on the company's articles and the circumstances. Under the model articles for private companies limited by shares, a shareholder is entitled to a replacement where a certificate is said to be lost, stolen or destroyed, although directors can require evidence, an indemnity and a reasonable fee.

How long does it take to replace a lost share certificate?

There is no universal turnaround time for every UK company. A straightforward replacement may be relatively quick, while a case involving missing company records, disputed ownership, inheritance or a substantial shareholding can take considerably longer.

Do I need a solicitor to replace a lost share certificate?

Not usually for a straightforward case. However, legal advice may be sensible where ownership is disputed, the company has incomplete records, the shareholder has died, multiple parties claim the shares, or the certificate is connected with a significant transaction.

Does a replacement share certificate have a new certificate number?

The company can determine how replacement certificates are numbered within its record-keeping system. It should clearly record that the new certificate replaces the lost one and avoid creating confusion about the status of the original.

Does replacing a share certificate affect my dividends or voting rights?

No, not by itself. A replacement certificate documents the existing shareholding. It does not normally alter the rights attached to the shares.

Can a UK company issue an electronic replacement share certificate?

The practical position depends on the company's articles and the requirements governing execution of its certificates. Companies should not assume that an ordinary PDF automatically satisfies all applicable requirements. Where there is uncertainty, the company's articles and professional advice should be checked.

Conclusion

Losing a UK company share certificate is usually an administrative problem rather than a loss of ownership. For a private company using the model articles, the process is clearly contemplated: a shareholder whose certificate has been lost, stolen or destroyed can request a replacement, while the directors may require appropriate evidence, an indemnity and a reasonable fee. The practical process is straightforward:

1. Confirm your registered shareholding.
2. Check the company's articles.
3. Notify the company in writing.
4. Provide evidence if requested.
5. Sign an indemnity where appropriate.
6. Pay any reasonable replacement fee.
7. Have the company issue and record the replacement certificate.

Most importantly, remember that replacing a certificate does not create new shares. The company's register of members and other statutory records remain central to establishing the company's ownership structure. For founders and global business owners, maintaining accurate share records from the beginning is far easier than reconstructing ownership years later. A UK company formation and management platform such as IncorpUK can form part of that wider administrative infrastructure, while unusual ownership disputes, inheritance matters or complex share transactions may require specialist legal advice.
