Yes. A spouse can be named as executor of a will. A spouse can be appointed by the court if there is no named executor or the named executor cannot serve.
If you are writing a will, then you need an executor. However in this case where you are leaving everything to her, she can be the executor.
It makes a lot of sense to make them the executor. It is very common for the spouse to serve in that capacity.
It is not automatically made the wife. The will itself can specify someone. It is often the case that the court will appoint the wife if that is her wish.
This is very common in estates. It makes sense as they are the ones that will benefit.
You haven't been specific enough in your details. If the husband died first while the wife was living and property ended up in the wife's estate, and from there went into a trust, then the property may be out of reach of the husband's executor. It depends on how the couple held title, if husband's interest passed to the wife while she was living, if the husband had any creditors, and the laws in your jurisdiction.
You really don't need to do anything because you aren't the executor yet. If your mother dooesn't change her will before she dies then at that time you can file a declination with the court as the named executor. The court will appoint someone else.
Not if the husband is still living. If he is deceased, the executor can obtain the records.
No. Not unless his wife is a named beneficiary. If he is allowing estate or trust property to be converted he should be reported to the court and removed from his position as executor/trustee ASAP. If he has illegally removed property it should be replaced.
The court must appoint the executor and will appoint the person named in the will by the testator unless that person declines, is deceased or is determined to be unfit by the court. In that case any one of the surviving children may petition for appointment and if there are no objections that person will be appointed executor.
You should consult with an attorney and file a petition to be appointed the administrator of your wife's estate as though she died without a will. Her heirs-at-law will be notified of the petition and be provided with an opportunity to object. If there is a will then the person who has it will likely produce it. They may then file it for probate. You would have a viable objection to the appointment of the named executor in that will since they have already displayed evidence that they would be a hostile executor. You could petition to be appointed the executor. If the will is not produced then the estate would be distributed according to the intestacy laws of your state. You would reveive a share of your wife's property by law. You can check the laws out at the related question link provided below. You should contact an attorney ASAP.
The wife controls 75% any children split the remaining 25%. However, if there are no children wife controls 100%
Yes, and they frequently are as in the case of the standard husband and wife will, where each spouse leaves the entire estate to the other spouse and names that spouse the executor.
