Tendering an Instrument in Good Faith. A good faith agreement is a covenant between two parties that promises that neither will do anything to damage the other's right to receive contract benefits.Our business legal services include everything from analyzing, drafting, and reviewing contracts to contract negotiation and litigation.

You are not required to be completely transparent. Proposed change and the change in the contract price.
