Does a quit claim deed override the will?

It doesn't override the Will, as such, however in effect the answer to your question is "yes." The Will only touches those things your aunt owned when she passed away. When she deeded the house to you, she no longer owned it. To the extent that the value of the house exceeds the value of assistance that you paid to her, other heirs might bring an argument that you hold the house in a constructive or resulting trust. Basically, though, you've owned the house for seven years.

If your aunt properly executed the quit claim deed which accurately described the property and put it in your name, and if the Quit Claim Deed was recorded with the county recorder in the county in which the property is located, and the quit claim deed should override the will. The point here is that a properly executed quit claim deed constitutes an immediate transfer of the property once it is recorded but a will only takes effect once the testator has died. By executing and recording the quit claim deed, your aunt removed the property from her own estate and put it in your name before she died and passed on her estate under the terms of the will.
