If you own a home and then get married does your spouse half of it?

It depends on the jurisdiction and the specific circumstances. In some jurisdictions, property acquired before marriage is considered separate property and is not subject to division in the event of divorce. However, in other jurisdictions, property acquired during marriage is considered marital property and is subject to division in the event of divorce. Additionally, some jurisdictions may have specific rules regarding the ownership of the home if one spouse contributed to the purchase or mortgage payments before the marriage. It is important to consult with a qualified attorney to understand the specific laws and regulations in your jurisdiction and how they may apply to your situation.
