It seems the debt is community and the community estate is responsible. There really is not a splitting just because of a death. Even the OPs separate property can be taken for the debt as I assume it was obtained during the marriage. The house is the security which is why Mr.Knowitall asked the question he did. Without all the facts, the particular question cannot be answered as the whole of the situation and why it matters is important. But, if one wanted to do what is "fair" or equitable, the asset that secures the debt is the portion that should be responsible for the debt. I suspect the OP is not intending to sell and does not particularly like the implications of the question.
