I need to change some pricing in a service contract that has already been signed by all parties. The original contracts states that cost may be increased due to a specific set of circumstances. Those circumstances have occurred. Do I call the additional part of the contract an "amendment" or is there another more appropriate term and are there any rules about how it needs to be formatted and signed?

Hello d:

I would write them a letter explaining that the particular circumstances noted in paragraph #?? have occurred. I would then detail those occurrences, and tell them that you are invoking your remedy. Tell them exactly when the new pricing comes into being, and what to expect.

I'd finish by saying that your letter amends the contract and becomes a permanent attachment.

Send your letter certified, return receipt requested.
