Can a creditor force sale of jointly owned home of unmarried couple when owed by one owner, upon death?

If the house is currently owned by both of you as "Joint Tenants With Right of Survivorship" no a creditor cannot attach his interests in the property at any time .. before or after death..If the house is owned by both of you as mere "joint tenants" or "tenants in common" there is a potential that his creditors can attach his interests after he passes. Look at your deed.. if it does not actually say "with a right of survivorship" you are most likely mere tenants in common. Further even if they can force it.. they can only get 1/2 of the equity.. the other 1/2 of the equity is yours.
