I'm going to assume that your nana has actually passed away (it does make a difference - you have no right to access a copy of the will if she is still alive). Also ask yourself whether you are sure that there is a will.
The first thing you should do is to see if probate has been sought for the will. That's easy to do. Go here:
Party search Search in the Supreme Court under your nana's name as the 'Party details'. If you get a matching result, it will tell you the applicant(s) and the date applied. The applicant(s) are usually the executor(s). Then click on the 'View file details' link, and this will open up further details. What you'll be looking for is:
- 'Representative' under 'Parties' - This is the name of the law firm handling the probate application, and will inform you where to direct your enquiries;
- 'Events' - To see if anything untoward has occurred;
- Under documents there should be a number of affidavits. Usually you'll see one for each executor, and one from a lawyer (this is for the advertising and notices compliance). That will generally give you a name of the person at the law firm to make the enquiries of.
- Under documents you'll also see a document listing for the will (you can't apply for probate without it). This will tell you that the original will has been deposited with the Supreme Court, and also that the solicitors acting for the application have a copy of it. You can get a copy from the Court directly, but you should be able to easily get it from the lawyer.
Be aware that if the application is for 'letters of administration' rather than probate, that indicates that there is no will - and the estate will be divided up according to the intestacy rules.
If that doesn't work, I'd suggest writing to the lawyer to inform them who you are and ask these very specific questions:
1. Are you acting in respect of the deceased estate of [nana's name]?
2. If yes: Please provide me with a certified copy of the will in accordance with section 33Z of the Succession Act 1981 (Qld). If you do not have a copy of the will, please outline the steps taken/to be taken to search for the will. Further, once the will is located please send me a certified copy.
3. If no: Are you aware of who is acting in respect of the estate? Please provide their details.
If they continue to play the 'no will' game, see if the private investigator can track down the solicitors your nana may have used to create the will. Make enquiries with them (be prepared to have to provide proof of your nana's demise, and your standing as her grandchild). If the firm is no longer around, contact the Queensland Law Society to ask where that firm of solicitors' safe custody has gone.
Another option is to search via the Queensland Public Trustee to see if they hold it, or (as a long shot) your nana's bank.
