I am sorry to hear about the passing of your father on 5th February. In order to claim his PF balance, you will need to follow certain procedures. Typically, to claim the PF balance of a deceased member, the nominee or legal heir needs to submit a few documents such as the death certificate, legal heir certificate, PF withdrawal form, and any other documents as required by the Employees' Provident Fund Organization (EPFO).
It is advisable to visit the nearest EPFO office or check their official website for detailed information on the process to claim the PF balance of a deceased member. It is important to ensure that all the necessary documents are in order to facilitate a smooth claim settlement process during this difficult time.
I hope this information helps, and I extend my deepest condolences to you and your family during this challenging period.
