If you own the house prior to the marriage and do not add him to the deed after you marry, then the house should remain your sole and separate property. This means that if you later divorce, he would not have a claim to ownership of the house (but he might have a claim to be reimbursed for money spent on the house, like the mortgage or repairs/maintenance) during the marriage. I recommend you consult with an attorney who can provide you with more specific information, and that you also obtain information about whether a prenuptial agreement would be appropriate in your situation.

No he will not if you follow some basic rules, such as: 1. Do not put his name on the house; 2. you pay the mortgage payments (if you don't have sufficient money, then he needs to give you a "gift" every month in the amount of the mortgage. 3. If he is willing, have him sign a document stating that the house is your separate property and he understands and agrees that he will not have any financial interest in the house after the marriage. I don't know your specifics, but something like the foregoing will be required to ensure that the house remains yours.

In Washington, your house that is owned by you before your marriage will normally be characterized as your separate property. Typically, that means that it will not be part of the community property that you and your husband accumulate after marriage, that would be divided up if you happen to get divorced some time in the future. However, there are ways that the community could have financial claims against the separate property home, depending upon subsequent improvements made to the home, the payment of the mortgage, and any other factor that may be a significant community investment of money or time in the house. While you could rely on the statutory law to protect your investment in the home, many individuals enter into prenuptial agreements that clearly preserve separate property ownership of the home under any of the previously mentioned conditions.
