Qadha for Qurbaani

Q: A person has many years of missed qurbani that he needs to make up for by paying market values.

1. Must he use the market value of a local animal (which would be expensive) or can he use the market value of a cheap country (such as the value of 1/7 cow in India)

2. Should he use the market value for the current year, or should he use the market values for the past years when he missed the qurbanis?

Q: How should a person make qadha of the qurbaani of previous years?

Q: If one missed qurbaani, will he have to pay the price of the whole animal for every year or one share for every year?

Q: How do you find out the current value of a qurbani animal so one can fulfil a qadha qurbani?

Q:

1. A person who lives in the UK on whom Qurbani was Wajib but didn't do Qurbani for some 4 years, will it be permissible for him to send money for Qurbani to India for 4 shares in big animal?
2. In the above situation will it be permissible to send Sadaqah money to India the value of 4 parts in big animal in India?

Q: A person did not make a waajib Qurbani one year thinking that he did not own the amount of nisaab. He instead made a nafl qurbaani. After some years he realised that he had wealth put away which would have made qurbaani waajib on him. What does he do? Will the nafl qurbaani be counted for that years waajib qurbaani?

Q: A person upon whom Qurbaani was waajib purchased the Qurbaani animal but did not slaughter the animal until the days of Qurbaani passed. How will he make qadha for the missed Qurbaani?

Q: A person upon whom Qurbaani was waajib did not make Qurbaani until the days of Qurbaani passed. How will he make qadha for the missed Qurbaani?
