Irish rules on the administration of estates could be very different to the US, but there are probably similarities.
In Ireland, a will is a document of public record only when it is admitted to probate. At that stage, it can be inspected by any member of the public at a court office known as the Probate Office. This is in effect a branch of the High Court, but is more like a government office. You don’t need a lawyer to do this, there is no court or judge involved.
Until the will is admitted to probate, the only people entitled to see it, or even to know whether or not it exists, are the executors. They are perfectly entitled to tell the beneficiaries absolutely nothing about the will, including the lawyer’s details. It will be of no benefit to you to contact the lawyers who are administering the estate, as they act for the executors and cannot by law tell you anything.
In relation to the length of time involved, two months is not at all unusual. In Ireland it is possible to wait six months or a lot more before receiving anything from an estate. It depends on how many assets a person owned, how complicated the estate is, the lawyers, and the executors etc. In your case, as the money is divided between several accounts, two months is not long at all for the banks to sort it out. It is possible in Ireland to apply to court to force executors to administer an estate if they take a ridiculously long time, but realistically that could mean years of waiting first.
As far as the amount of money involved goes, it is not at all unusual for people to believe they are being left far more than they are. It is common for people’s assets to go down in value between the time they make a will and tell people about it, and their death. It does not necessarily mean the will was changed. If the will was changed, the only person who could have done that was your grandmother, not the children. If you have evidence that she was taken advantage of by her children and persuaded to change her will to benefit them, you could take a civil action in relation to that to have the will set aside, but you would need legal advice in relation to that.
In Ireland, you do not have to claim an inheritance. It is paid out to you without your involvement. However, there would be a time limit within which to make a claim if you feel that there has been some kind of fraud. This limit would run from the date of the Grant of Probate of the will, as it is only then that you can know what you are in fact entitled to. Again, take legal advice on this, but the best way to resolve these disputes is to keep things as civil as possible. When these disputes end in court, it is very messy, time-consuming and costly. Avoid if at all possible!
