If your grandmother died with property in her sole name and had no Will, then her estate would pass to her surviving heirs. In this case, that would be her children and the descendants of a deceased child (i.e. your father). So yes, since your father predeceased his mother, you are a surviving heir of your grandmother, and if she had no Will, you are entitled to a portion of her probate estate. Understand that her probate estate included only property in her sole name and would not include...
You have to be an heir (or beneficiary in a Will) to contest a Will. Heirs are determined by state law. Close relative is not enough information. We need to know marriage, children, grandchildren. If none, then parents, siblings and descendants of a deceased sibling.
The trust can't go against the will. The trust controls property titled in the trust and the will controls property titled in the decedent's sole name. If the total of the assets passing under the Will is less than $100k (not just your share, but the total) then you may be able to use a small estate affidavit. If it's more then someone will need to file for probate. Typically that is the executor named in the will. As for the trust, if you know who the trustee is, then inquire directly...
Yes, it's still valid in a technical sense, but a move to a new state is a good trigger to have your estate plan reviewed. There may be adjustments that will be advisable. Also consider new Illinois-specific powers of attorney.
My condolences on your loss.
Property in your relative's sole name will pass, to the decedent's heirs, through probate. Heirs are spouse and/or children and descendants of a deceased child. If there is no spouse or descendants, then property passes among parents, siblings and descendants of deceased siblings.
One or more of the heirs should contact a local probate attorney about starting the probate process. Nothing will be able to be done until a probate estate is opened.
Unless Disney opened a park in Illinois (if so, please don't tell my family), then this is a Florida (or California) probate law question. Timeshares can be a real hassle to transfer. The attorneys are quoting for the time they will need to spend.
Also, before your daughter jumps in, she needs to also determine whether he has any other possible assets that need attention as well. Doing everything right the first time can save headaches down the road.
If you're the administrator for the estate, then you should have a probate attorney. This is something you should be discussing directly with your attorney. If your sister cannot be located through good faith efforts, her notice can be made by publication. If she still can't be ultimately located, then you can petition to have her share of the estate deposited as unclaimed with the county treasurer. As suggested by Attorney Pankowski, a search firm might be helpful as well.
What taxes are you worried about? Life insurance payout is not taxable income. Only interest after death is income. Talk to a tax accountant or tax attorney for specific advise based on the terms of the trust and future distributions.
Certainly yes, and this is not unusual at all. The legatee would be the trust in care of the acting trustee of the trust. Provide with the identity and address of the trustee, and if needed, the Tax ID number for the trust. The funds should be made payable to the trustee of the trust and the trustee adds to the trust and disposes of under the terms of the trust.
