When the time comes, if you are still worried, you could be in touch with the local Probate Registry to enter a "Caveat" which means that if your sisters were the Executors and they applied for a Grant of Probate, you would have to be told that they had done this. Then it might be best if you find a Solicitor of your own, to be in touch with them or their Solicitor, to make sure you see the Will. A Solicitor would help make sure that you get whatever you are entitled to under the Will, hopefully without the need of Court Proceedings. If there is no property and not much money, and so no need of a Grant, a Solicitor's letter would also make them realise that they have to do things properly if they're not employing a Sol. themselves. Sorry this is so late, but it might help anyway....
