There are two (and sometimes three) ways for two people to hold title to real estate in most U.S. states. (I’m running late, so I’m just going to hit the high points. I’m also going to ignore land trusts and various corporate or partnership methods of taking title.) First is tenants in common. A & B own the land. Can usually be in shares other than 50-50, if so specified. Both A can sell or bequeath their respective shares to third parties. No particular immunity from creditors.
Second is joint tenants. Usually has to be 50-50. Usually is deemed to have right of survivorship (best practice is to specify this, though.) This means that the survivor automatically gets the share of the first one to die. Creditor will have some difficulties in attaching share of one of the owners who owes a judgment.
Third possible method, allowed by some states, is tenancy by the entireties. Only allowed for married couples. Similar to joint tenancy, but with better protection from creditors.
As implied, rules vary by state. The wording can matter. Also, what form of ownership is implied when the deed is silent on the issue will depend on state law. (Most states deem it to be TIC, IIRC.) How this is done can make a big difference in what happens if one of you dies, or has a judgment against you. See a lawyer licensed in your state for advice that you can rely on.
