Update to previous post about LeGaLiSaTiOn 

With Reference to point 2. Apostille and the cost of £30!!

While this is true... certain documents will need to be signed by a Notary first. So this has the notary fee as a cost element to it. Therefore it will cost around £70 for the Apostille of a Bachelors Degree.
The notary I used Kindly offered to do it for a reduced price of £30

 This is not mentioned on the Apostille page of the FCO website.  You need to check the type of documents in the "documents we can legalise" section.    For info Click >here<

An Extract from the FCO website...

2) Appropriate certification:

We can legalise original certificates of UK academic qualifications if:

• They have been certified in the UK by a practising UK solicitor or notary public

Or

• They have been signed and certified by an official of the British Council 

We can legalise photocopies of certificates of UK academic qualifications if:

• They have been certified as a true copy of the original in the UK by a practising UK solicitor or notary public

Or

• They have been certified as a true copy of the original by an official of a British diplomatic mission (e.g. Consulate, Embassy or High Commission)

Legalisation of Documents >>>  There are 2 different "Legalisation of documents" that you will need to get your head around when you apply for your Korean visa!

1. Notary
2. Apostille 

If you have a sponsor (In my case my wife) to support your application (I think in the case of E2 visa applications - this will be the school your contracted to work at) you will need to get the document witnessed and  stamped by a notary. Basically this is all it is they watch you sign then stamp it to say they have witnessed it.  They will need to see ID of the  sponsor and your CASH! - You can find a local notary >HERE< they are usually based at a solicitor, but not all solicitors have a notary! 
Prices vary . There are 2 in Peterborough they quoted £60 and £50.  I was surprised that the guy wanted cash and didn't give a receipt ... I guess you just expect solicitors to work within the boundary of the law and pay taxes like everyone else!!! or is that just me?

The  second is the Apostille. - THIS CAN ONLY - be issued by the foreign Office it costs £30.
These guys offer to take the pain out of it for you but will charge you £79.79+VAT
