Do i need to do Marriage Registration? If yes how? Plz read the case....

Here is a real case: Mr. A and Ms. B are from UP.. .. married since 2018. Marriage was solemnized at UP. Both are working now in other state. In late 2018, Mr. A tried to register to marriage using UP Govt web portal: https://igrsup.gov.in/igrsup/groomDetailsA# ... ... filled details online and submitted... ... got acknowledgement number generated. But there was no success in paying the fees as the payment link was dead. Then, Mr. A printed the submitted form and went to Office of the Registrar, of his District. From the subordinate officer, he came to know that online filled-in form was useless. Mr. A has to start the registration process again, offline. Also, he has to produce his parents and wife's parents before officer and documents like letter from Municipality Chairman are also required. Mr. A could not do that as he never had the opportunity to get parents from both sides at one place again. The process he was told in the office looked like it was full proof way to stop people from registering the marriage. Mr. A wants to register his marriage. Every year in summer he would come to his home place in UP. Is there any way to register his marriage in that time? --------------------------------------------------------------------------------------------- NOTE: In the meantime, Mr. A renewed his passport and declared his wife's name in the place. They did not ask him any certificate of marriage. He got his passport with his wife's name (A changed the surname of wife, i.e., added the family name). Based on passport, he applied for modification in wife's PAN and Aadhaar card and received recently. In new Adhaar card, his wife has got his family name and his name as her husband is also mentioned. In view of the recent developments, when his wife has Aadhaar card saying Mr. A is her husband Ms. B has got surname changed (surname of Mr. A’s family) does Mr. A really need a marriage certificate?
