Yes. The will can be left indefinitely by the executors unless some third party brings proceedings to compel them to act or have them removed and replaced.Sorry to keep asking questions, just like to be prepared, so if the executors say they are not going to send the will forward until the beneficiaries agree to the debt being paid or unless we reached a compromise with them, the will can be left indefinitely , with the only other alternative being to get them removed, which as you say is an expensive process? And then they could challenge the will if they were no longer executors,( that also comes out of the estate)
If they’re replaced as executors, they can put a claim in with the new Administrators for the debt they say is due. If that ends up being contested, the result is that it ends up before the court and the costs likely to come from the estate.
