How to make a document legally acceptable in a foreign country

Suppose you have a property in a foreign country and you want to authorize someone to manage or sell it without you going to the country at all.  You can write an authorization letter and make it legally acceptable in the foreign country as following:

1. Print out the document, but do not date or sign it.
2. Bring it to a public notary.  Many places offer public notary service.  For example, TD Bank that is known for its excellent customer service offers the service free of charge. 
3. Follow the notary's instructions to sign and date the document. The notary needs to understand the document.  A TD bank's notary sent the scanned copies of documents in a language that he does not understand to a colleague in another location by email, talked with her over the phone to verify the contents, then he affixed his notary seal to documents and signed them.
4. The notary needs to fill and sign a notarial certificate that depends on which of the four notarial acts is performed by the notary: acknowledgment, jurat, signature witnessing, or copy certification.
5. Bring all of the above documents to the office of the secretary of the state to get the apostille for the document.  Massachusetts charges $6 for each apostille.  
6. Submit all the above documents and a required ID (e.g. passport) to the embassy or a consulate generate of the foreign country for legalization.
