Different states have different procedures. If one owner dies, ownership and registration may be transferred to the survivor without going through a court probate proceeding. If she wants her lover to inherit her share, she must have a will or living trust so stating. If one person dies, ownership passes automatically to the survivor. In many states, creditors won't let the buyers put title in joint tenancy until the loan for the purchase is completely paid off.
Joint tenancy requires both signatures to sell or give the property away.
Only legally married couples who are married on December 31 of the tax year can file joint income tax returns. If one partner supports the other, however, the supporter can file a tax return as a single person and claim the other as a dependent. Citizen or resident. The supported person must be either a U.S. citizen or resident alien, or a citizen of Canada or Mexico. Nontaxable money, such as gifts, welfare benefits and nontaxable Social Security benefits don't count toward gross income.
