Exclusion of inherited properties from the absolute community of property

Dear PAO,

My husband and I got married in May 2006, and we have five children together. Our relationship turned sour, and we have been living apart for the last three years. Recently, I found out that his grandmother died and left him a farmland as his inheritance. We do not have any agreement whatsoever regarding our properties. Since our combined incomes are not enough to support our five children, I asked him to give me half of the income from the farmland, but he refused. Is he right to refuse my request?
