What happens to property when a disclaimer is filed and the will does not list a contingent beneficiary?

In California, disclaiming an inheritance means the gift is treated as though you predeceased the testator; i.e., it would pass to your wife and children, if you have any. If that is not what you want to have happen, then you may simply refuse to accept delivery of the trailer. No one can be forced to accept a gift or an inheritance, although acceptance will be presumed unless you make it clear that you are rejecting it, such as a letter to the probate court. If your disclaimer or refusal is effective to keep the trailer in the estate, your siblings may be correct; the property would pass by intestate succession, as though there was no will, and if there is no spouse, children or parents to take, then it would go to the siblings and to the children of any deceased sibling, by right of representation. Again, everyone that doesn't want anything to do with it can simply refuse to accept it. The appropriate local agency (Public Guardian?) should be contacted to dispose of it.

It would be treated as though there was no Will so the estate assets would pass to his siblings, who also could refuse to be heirs. ?If none of the relatives are willing to accept the assets, it would go to the State.
