I am not clear on the facts. Is your grandfather still living? We would also need to see how the deed to the property is titled and what you want to do with the title. I would suggest you contact a probate attorney to discuss the title to the house and how to transfer it.
You would need to consult an attorney to see how the deed is worded. Depending on the wording most likely the person that died came off the title and the two remaining people own it equally. Again I would consult an attorney to review the wording though because it is very important to see how it is worded as to how it passes.
You will need to have a probate or real estate attorney review the deed. If it is titled properly giving him a life estate and you the remaining interest you would just need to record a death certificate in the county where the property is and it would pass to you assuming you have the remainder interest. You need to have it looked at first though.
First a probate will need to be done to transfer the house unless the deed had language transferring it to the heirs upon your grandmother's death. Once the probate court transfers the homestead property it sounds like there will be multiple owners. You would each have a right as owners to live in the house. I would suggest contacting a probate attorney to walk you through your options.
There is a Florida statute that the Will must be deposited in 10 days, but you will not get in trouble for not doing so. As far as what to do next, if your husband had no creditors (did not owe anyone money) then you will want to hire an attorney to do a Petition for Summary Administration and a Petition to Determine Homestead. The judge will enter an order transferring the homestead into your name. If your husband had creditors you will have to do what is called a Formal Administration, but...
Under the intestate statute of Florida Law if your sister was not married when she died then her daughter (assuming she was the only child of your sister) would have inherited 100% of her estate, including the homestead. If the daughter is deceased, but had two kids then they inherit the estate equally. I would suggest you contact a probate attorney to discuss this though. I practice probate law all over the state of Florida and am happy to give you a free 30 minute consultation on this issue.
In order to maintain a wrongful death suit a Personal Representative will need to be appointed. You will need to find a probate attorney to help you open a Formal Administration. A PR will be appointed. There is a priority of people entitled to serve as PR which you will want to speak to your attorney about. If I can assist you with this process please feel free to contact my office.
It all depends on how the property is titled on the deed, as well as what the trust and the Will say. If the property is in the name of the Trust already then you can transfer it as trustee (subject to trust terms and approval). If there is what is called a "pour over" Will and the property was not in the name of the trust and just in the name of the decedent then it may have to go first into the trust and then out. It all depends on the wording of the various mentioned documents. I would...
They will most likely talk to you once you have been appointed as the Personal Representative of his estate and the Judge signs Letters of Administration. You should consult a probate attorney to determine the procedure to do this.
