Hi Rajhans,
As you said that after 7 years of service you were transferred to their UK based company, whether said company is a group company or subsidiary? Whether your FnF has been processed? Whether any clause mentioned in your appointment or transfer letter that your services with UK based company will be considered for gratuity? Why not you were paid gratuity while transferring your services? your transfer is based on deputation or with any other condition?
Answer of these question will help us to provide proper feedback.
