Fay, everyone has been giving good advice, but I would find out what law actually applies in this situation. If it's British, then you head down one path, and if it's Egyptian, you head down a very different path.

You may not even need to write a letter at all.

That being said....

I would be more than happy, however, to honour the contract that I signed with you last year if you would care to sign your copy.

Don't say this, because it implies that you haven't honored the contract. It may create more problems for you in the long run, In the U.S., contract law is based on 3 precepts: promise, consideration and performance. This doesn't fall under any exceptions to the "must have a signed contract at all costs" rules. He has been providing you with consideration (your paycheck) given your performance of the terms of the contract based on the initial promise. He's implied his acceptance of the contract. In theory (because I have no idea of what law applies, nor the factual entirety of the situation), he's well and truly screwed.

FWIW, Fay, I think he's going to pay you because he's more ineptly passive-aggressive than machiavellian aggressive-aggressive. He's a bully and an ass, and making baseless threats is pretty much his game.

Egyptian law, afaiu, only applies to contracts that are written in Arabic. And there are a whole array of Egyptian employment laws that he's cheerfully disregarding already, so I'm guessing that it'd be British contract law/employment law that would be relevant. Maybe.

I would be more than happy, however, to continue to honour the contract that I signed with you last year if you would care to sign your copy.

Better?

Golden Grahams:

Congratulations, Betsy! I hope the new position is all that you deserve (which is, to say, fabulous).

Will try hard to remain rational.

I think an appearance of rationality is all you really need.

You need to find out. Even if the contract isn't in Arabic, it still may be enforceable under Egyptian law. And if he's been flagrantly ignoring employment law, then he could be in for a nice hot boiling water bath.

Is there a clause in the contract that expressly states which jusridiction's law would apply should a dispute arise?

eta: Just saw your edit. Yes, that's better. The thing to remember is that IF you send that letter, it becomes part of the record. Every word will be scrutinized, and needs to stand up to any legal test they could throw at it.

Since I and Evil School have both acted in good faith in fulfilling the terms of the contract up until this point

This addition that Brenda crafted is very important, I think.

You think correctly, Tep.

The Bitches have spiiiiiicy brains. And I got my lawgeek on...

ita, were you about to recommend a messenger bag when you asked if I needed to carry gym shoes, or was it just a fetish thing?

No -- it was just that it'd make a big difference to the size of the bag, so I wanted the people who have a clue to have the correct specifications. I'm just a business analyst -- assisting others to architect the solution.

God, it's only Monday.
