Had a will, giving her son everything. Her son recently died and we discovered he never transfer the real property or went through probate. He did not have a will or any children or a spouse. Can we file these estates together? Due to what her son did with her assets, there is really no way to separate the estates.
These are still two separate estates and depending upon when he died he may be under the MUPC . You have not stated whether your aunt had other children or was married, either, nor whether aunt's Will was probated. You should have a Probate attorney handle this matter as there are many issues which could be applicable .
