How to change beneficiary name for my house

Houses do not have beneficiaries in Georgia. There are only either joint owners who hold rights of survivorship or persons who receive the property through the probate estate of the deceased owner at the owner's death. If you want to change who will receive your house when you die, then you need to (1) ensure that you own the property in your own name, not as joint tenants or tenants in common with anyone else (if there is already another person on the deed it may be too late, unless they are willing to give their interest back to you) and (2) ensure that your Will (or a revocable trust) says that your assets (or at least the house) will be distributed to the desired person at your death.
