There are any number of reasons that the clerk at the recorder's office would not accept the quit claim deed. As a previous response noted, that quit claim deed may not have to be filed. I'd also suggest contacting an attorney that has some expertise in real estate law to discuss this matter. You may find out that you do not need to take any further action and that recording that quit claim deed (or any other document) is not necessary.
Please accept my sympathy on your loss. Even in an estate such as this where summary administration may be available, an attorney is usually required to file the appropriate pleadings.
