Rs72000 to pay to the government for not paying registration tax?

My father bought a ford icon in 1998 from Maharashtra to Karnataka. He didn’t pay the registration tax to the government and now it has climbed up to Rs72000. He also filed a case in the court and lost it. He passed away 2 months back and now is it us, his children’s responsibility to pay this tax?? Can we avoid it in any way?? Awaiting immediate responses.

Thank you very much

Why do we have to pay taxes to government?

What benefits do we get when we pay substantial amount of taxes to government in India? How does countries like Dubai survive even if they have no tax system in place and still have far superior quality of road transport, metros, airports and far superior then us in almost all areas?
What I want to know is that what benefits do I get by paying taxes to government?

Why don’t the Government make liberal Income Tax laws for the salaried class in India?

The salaried class in India usually have limited source of income, yet this class have got to burn mid-night oil and be always on the lookout for new investment opportunities through which they may save for the rainy days as well as get some rebate in Income Tax under various Sections of Income Tax laws unlike big industrialists, businessmen, film stars and some sportsmen, a good number of whom often cheat Government in paying Income Tax or become defaulters, as reported in the newspapers from time to time.
