You should write to Computershare
telling them you have mislaid your certificate. They will send you a letter of indemnity to sign and return to them. The indemnity provides you with cover for any loss arising from a dispute over ownership of the missing shares. An administration fee is usually charged for this service.
If the value of the shareholding represented by the lost or misplaced share certificate is more than £100, the indemnity must be countersigned by a bank or insurance company, which may also charge a fee. Alternatively Computershare offers a countersignature service where the value of the shareholding is between £100 and £50,000 upon the payment of an insurance premium. A sliding scale of charges applies, depending on the value of the lost certificate to reflect the greater risk to the insurer.
If the value of the shareholding is greater than £50,000, the broker Portsoken Ltd, 4th Floor, Davis House, Robert Street, Croydon, CR0 1QQ (T: 020 8667 2107) may provide a countersignature service for a fee. They can deal with shareholders domiciled outside the UK subject to normal identity and sanction checks.
Please check to ensure that the certificate has been lost before informing Computershare in order to avoid incurring any fees (as outlined above).
To request an indemnity please contact Computershare advising them of your full name, address, the company in which you hold shares, the certificate number and amount of any share certificate(s) still in your possession.
