Various masaail of talaaq

How does one determine what type of talaaq is issued?

Q: How does one determine that a person issued a particular type of talaaq to his wife. If a talaaq is used as 'I divorce you' how does the poor wife know if this is a talaaq-e-raj'ee (revocable talaaq) or talaaq-baain (irrevocable talaaq). Does it depend on the intention in the heart of the husband and if so how does the wife know which type of talaaq is issued?

Husband passing away while the spouses were separated

Q: Me and my husband were living separate and the divorce proceedings were in the court pending . Legally we were not divorced and he never said divorce word to me and while the divorce was pending he passed away his parents and family did not contact me about his passing away and when I said to them he was still my husband because divorce wasn't through yet they said no, in our eyes you are divorced and you have got no right to know he passed away. My question is, was their behaviour right about not letting me know about my husband and telling everyone that they are divorced although divorce wasn't through yet ?
