LIC Surrender value - Enquiry

Hi dimers,

My dad is having a LIC JEEVAN LABH (836) policy with a term of 21 years and date of maturity is 2040. We have paid 50k premium till now. I don’t see any value in continuing the policy. Is it wise to keep the policy or surrender it?

Also, any idea on how much premium will be returned if i surrender it now?

Thank you!!
