You use the term "succession," so I'd encourage you to note that this is the Oregon area of this website. If you're not in Oregon, my answer won't apply. The answer to your question depends on when you and your husband bought the house. In general, spouses own real property in Oregon as "tenants by the entirety," which is a survivor-ship estate. At certain times in the last 30 years the law required that your deed actually state that you are husband and wife, in order to create tenancy by the entirety. If it didn't say "as tenants by the entirety" or "husband and wife," then you would be tenants in common, in which case your late husband's part of the house would be in his estate. If your husband had any children who are not also your children, then his children would own a part interest in the house. If not, then you would still own the whole house, but you'd have to do a probate to transfer his half to you.
