1. Contact a lawyer: If the parties find that there are problems with the letter of understanding, such as tax issues, they should contact a lawyer for help and advice in time. Lawyers can independently and objectively review cases and provide professional guidance for the parties to solve problems.
2. Contact with the court: If the parties find that there is something wrong with the contents of the letter of understanding, they can also contact the local court for consultation or request re-examination. In some cases, the court may have a judge to represent the parties and can assist in handling related affairs.
3. Please cancel the letter of understanding: if the parties find that there are serious mistakes or improper behaviors in the letter of understanding, they can apply to cancel the letter of understanding. The cancellation of the letter of understanding needs to be examined and approved by the court, so it may take some time and energy.
