Unfair dismissal - time limits for pursuing compensation
How long do you have to claim?
An application to an Employment Tribunal should normally be made as soon as the employer has given notice of dismissal and should be received within the period of three months beginning with the employee's effective date of termination.
If the application is received any later than that date the Tribunal will consider the complaint only if they believe it was not reasonably practicable for the employee to have made the complaint within the three-month period and that it has been made within such further period as they consider reasonable.
Unfortunately the time limit is very strict so we would be unable to help you
