My name isXXXXX have been a licensed attorney for over ten years and will be assisting you today.
There are a couple good ways to do that, and one bad way. Let's just focus on the two go ways.
One good way is with a will. You can make her your heir
and ensure that she gets the house upon your death. Once your estate
is probated she will get the deed of the house in her name.
Another way is to set up a trust, where you are the current trustee and she is the successor trustee, and you make her the trust's beneficiary. You would put the house in the trust.
Like a will, you can change the trust at any time if your relationship status changes.
Trusts work similar to wills but they do not require one to go to probate
court when the original trustee dies. The successor trustee automatically takes over. In the trust, you can give her the house upon your death.
Either a will or trust is fairly easy to set up. You can use a lawyer, or you can go to a self-help site like Rocket Lawyer or Legal Zoom and do it yourself.
