Normally, the money that comes to a woman before and during her marriage, she uses to buy land which belongs to her, but the husband has the rights to eat (own) their fruits (dividends), this is called נכסי מלוג. These are the exceptions:
1. Money she made from selling "(the rights to) her property, and kesuba"
2. Shtar mavrachas - land that she gave as a gift before the hupa to hide from her husband.
3. Gifts from her husband.
(Shulchan Aruch, Even Ha'Ezer 85.7)
Are there other exceptions that'll allow her direct use the money/property she acquired before the death or divorce of her husband?
For example, when the wife acquires the money through her own labor
1. By the husband forfeiting his right to the money his wife earns
2. By the wife forfeiting her rights to get fed and clothed
(Even Ha'Ezer 80.18 and 69.4)
