How write a legal letter?

Understanding how to write a legal letter takes a bit of practice, but the methods involved translate to most forms of letter writing, including traditional formal letters.

There are different forms of legal letters, but I'll highlight a few of the main points to remember when creating your own:

1. Include a reference number.  This helps both parties to understand which document is being discussed.
2. Ensure the letter is dated.  This is particularly important if there are deadlines to be met.
3. Make sure the address is correct.  Little mistakes make a legal letter worthless.
4. Begin the letter with Dear Sir/Madam, and end with Yours Faithfully.  Try to understand whether female recipients prefer to be titled Miss or Mrs etc.
5. Use a heading - for example "Re: Legal Thing"
6. Make sure your letter is clear and addresses the points at hand. Don't ramble.
7. Sign off the letter with a name, status, and company.  For example: Mr Man, Senior Partner, Man Solicitors.

That's about it! You could practice by writing formal letters to ensure that you're comfortable with the type of language you'll need to use.  Keep it simple, and make sure you remember all of the points above.
