For any private matters then the holder of the document is required to provide a photocopy of his/her valid ID (e.g passport or Driving Licence) please note the name on the official ID copy produced must be exactly the same as the document(s) which requires notarising - any discrepancy i.e middle name(s) not shown then the document(s) will be rejected.
Please speak further with us should you require full detail.
Also in relation to commercial documents then it is a requirement of the embassy that the legal representative's passport along with a company house document which shows the legal status of the company and of its representative be produced - again all names need to be present and correct - again please contact us if you require further information.
