Most documents that are required for use in Guyana need to be notarised by a UK Notary Public. Sometime they also require an Apostille from the UK Foreign, Commonwealth and Development Office.
Do check with the recipient or end user of your document in case there are any specific requirements to you and your documents.
As Guyana is part of the Hague Convention, then an Apostille is the highest form of legalisation that would be required.
Give us a call or email your documents in. We can then confirm our fees and availability.
