Countries have different rules but more than likely you will need,
(1) proof of identity and probably parents names as well,
(2) household bill of some sort in your name,
(3)passport no,
Perhaps if you gave the country, some people on here will have done similar and can give you more detail. Most places you deposit money in will have contact with Irish revenue for money laundering purposes and vica versa. As for questions from the Tax man and you not wanting too many questions from them? Hard to understand why as you're getting the property legally but to turn it into cash it will all be revealed anyway.
