Especially in the case of dissolution of a contract between a company and a vendor or another party to an agreement, a dissolution letter can be contested.
If the dissolution letter is sent as part of legal proceedings and the terminated party feels the grounds for termination are wrong, objections and appeals are common.
This happens a lot when an agreement is terminated because of payment defaults. The defaulting party rarely agrees that the underlying cause of the default has merit.
Most of the time, disputes about terminations of contracts are settled, resulting in the termination of the contract and what the parties feel are fair compensation for loss and expenses.
