In New Jersey, Yes, but I assume the sibling is a beneficiary. If not then the sibling cannot force anything because she has no interest, what we call standing, to sue. After 1 year a beneficiary can sue to get an intermediate accounting to show everyone and the probate court what has been done so far. You can also sue the executrix to have her removed and to forfeit her commissions. There is no law that says an estate must be completed within a certain time frame. In fact generally for the first year no one can sue the executor to force anything unless there is special cause to do so. But 3 years is a long time and you should definitely get at least the intermediate accounting. The 3 years is not, in and of itself, grounds to remove the executrix. But is is grounds to file a lawsuit asking for that and that should give her a jolt. This answer is given for informational purposes and is not to be taken as legal advice.
If you think that the executor is not fulfilling his/her/their role effectively then yes, go and see an attorney about this.
However, to save costs, first ask the executor(s) why there is a delay, there may be a very good reason.
There is no proscribed time frame. It can take years, even decades, to settle a complex estate.
Power of Attorney is to give the sibling mentioned and acknowledged by the mother to perform their affairs when the mother cannot such as paying bills; investing money, etc., and no one else can take the right away from the Power of Attorney mentioned since the mother requested this person, not even the sibling who is 40 years old and living at home. Once a parent dies the Power of Attorney no longer exists and the Executor (male) or Executrix (female) named will put the Will into Probate which will pay off any debts before the Estate is settled and any property or monies left will be divided as the parent's Will stated.
If your father had a will before his death, it will makes easier in dealing with his estate. If there is no will, it could take years before things finally get settled.
If it has just been found, yes. The deceased's estate has not been legally settled until it undergoes probate.
Consult the attorney that is handling your probate action for advice. You may have to come to some agreement to partititon the home from the remainder of estate in order to settle the estate.
They have to wait until the debts are settled. That may be as short as about 4 months. It can take years on a really complex estate.
Get a lawyer and sue to "Partition to sell" said property.
You haven't provided enough detail. The answer depends on who owns the property now. The parents estate must be probated in order for legal title to pass to the heirs under the Will or under the laws of intestacy if there was no Will. The legal owner can evict anyone who is not an owner.If the parent died while being the sole owner of the real estate and their estate was not probated yet then your sibling doesn't have the authority to evict you.
Sorry, but the property belongs to the estate. They can charge rent. Hopefully you will inherit the property, or most of the value of it when the estate is settled.
There is no prescribed time frame. It is however long it takes to value and distribute the assets properly. In some cases it can take many years.
