For me it was a similar case wherein I shared my dad’s passport for address and relationship proof along with my passport. Thankfully the police station people were supportive enough. My passport address was of Bangalore and I didn’t have any relative in Bangalore. Try to connect with local SP office and explain. Typically they do hear such complaints and provide support. They didn’t ask for anything else like aadhar.Yes I have been trying to explain the same to lady that look at my ITR and other documents but my bad luck she is adamant . Even my father gave them money but not sure what is the problem with them . Better I would have done it from Bangalore instead of UP but I have no relatives there so that is why I choose UP .
