If her home was sold after she drafted her Will, then the proceeds of the house is part of her estate. Once a house is sold, all of the fees and such are paid at the time the house transfers ownership, at the closing. Once the house is sold, the money goes into her bank account to use as she pleased.
So,, she has since died and has a Will, which names you and your daughter as her heirs (1/3 of her remaining estate to each of you).
Go to the town in which she died. WHomever has her Will should have filed it with the Probate court. The Probate court should have had a hearing, calling you to appear as an heir of the deceased. At which point you would be told of your inheritance and that of your minor child's. Sometimes the Will will request that a Trust Fund is opened on the behalf of a minor, but you will need to have the probate judge tell you what the Will states.
There will be someone named as the executor of the Will. That person must file an inventory of the deceased assets, both tangible (personal property) and monetary (bank accounts). And, then there will be a list of debts she owed upon her death, which will be subtracted from her estate before it is split in thirds for ou and your daughter. If she died while the house was being sold, her Executor of her estate (which should be mentioned in her will and appointed by the probate judge) will finalize and report that sale, the costs and the profits will go into a bank account to be distributed to her heirs.
Your best bet at this point is to call the probate judge in the town in which your relative died. If the Will was presented to the Probate Court, you should have received a hearing notice by now. But, do call and ask questions.
EDIT: okay, I just read your comments. Again, if you were in the Will, you should have not only received a copy, but you should have received a hearing date to appear. CALL the Probate Court where your relative lived and ask for a copy of her Will. YOU HAVE A VESTED INTEREST IN THE WILL if you are #1 Mentioned in the Will OR #2 If one of your deceased parents was a sibling of your relative who died.
