Lisa,
I was executor to my Mom's small home, I did an on-line will had it notarized and witnessed in her home state, the terms were very straightforward since I was the only child and my Dad had already passed. When she passed, you need to get a personal representative document with a tax id (with you as personal representative) from the state where she passed. You will need a death certificate, and Original Will to present to the clerk of the court to be assigned as personal representative.
You can do this yourself, but I had a lawyer do it for me, there are a number of steps you need to take and every state may have unique requirements for what is required. The bottom line is it takes 3 to 6 weeks between the time you apply and when the document is signed by a judge and returned to you. My case was simple as far as the money aspect went, my Mom owed no bills and a probate notice was placed in the local newspaper once or twice a month for three months. Mom's medicare bill was huge but absorbed by medicare. If you do get small bills from credit cards, we are not talking thousands here, a simple written note to the creditor's explaining you are not responsible for their debts with a copy of the death certificate is sufficient. You only have 90 days to view either parent's medicare account online after death and once it is closed it can be a pain to reconcile bills so keep that in mind.
A second more expensive way to go is with a trust, there are many types, and my wife's family used an irrevocable trust. This costs more and my financial advisor and tax attorney need to be involved. I would only recommend a trust if there are considerable assets to shelter. To date, we have had no negative issues to report so it was worth it and assets after death are NOT subject to probate, or haggling by people not named in it, it is secret and can never be disclosed, unless you choose to do so. One more thing, if there are other siblings and even if you have a will, any sibling who feels so inclined can contest it, and it can take 2 years or more to dispute in court and even then there are no guarantee's. If your parents assets exceed the states inheritance limit and you DO NOT establish a trust, then they are taxable when you liquidate them, you must pay the tax, Here in RI I think the limit is 850,000 and if there total net worth is one dollar over the limit, then the entire amount is taxable ! However, if you have a trust, set up properly, that is NOT an issue, something to think about, You need to find out what if any inheritance laws exist in the state where your parents have the full time residence. Many people here have second homes in other states and list them as their primary residence to avoid the inheritance tax. There are rules of proof I won't get into here, but you need to be aware of them, ignorance is NO excuse.
If bad blood runs in your family, or the value of their total assets become taxable at death, then a trust is the only way to go. If your parent's wish, they can designate who gets what and if other siblings are locked out, they can NEVER see it. A will on the other hand is public record, siblings, relatives, creditors and real estate people, thieves can and do look them up and do, so be aware. Many peoples vacant homes are robbed this way.
One more thing, you will need to file one last federal and state tax form for the year that they passed away. I may think of more things to report and will add them, but this is a good start. I hope everyone in your family likes each other and gets along, it makes things so much easier. Good luck.
