A: If you want this to be considered you separate property, the best thing to do would be to hire an attorney to prepare an agreement for you AND your husband to sign (assuming he will agree to sign). As the other attorney mentioned, the law presumes property purchased during marriage is community property (owned jointly), regardless of whose name it is in. You can convey your interest in the property through a Will, Trust or deed. If you don’t, the law will decide how the property passes after death. If it is community property, his kids may have a at least a partial interest (also depends on whether he has a Will). I suggest talking to an estate planning attorney about a separate property agreement, Will or Trust, and/or a Transfer-on-Death Deed. There are a lot of factors to consider, so I wouldn’t recommend trying to do this without an attorney’s assistance.
