Generally you should have your own separate lawyer. You may have claims against her and her insurance, and there are possible other conflicts of interest. If you do not have an attorney yet, feel free to call me at 404-768-3509. Do not make any statements to the other driver's insurance, or to your friend's insurance.
You've posted this on multiple internet sites and the answer won't change with each posting. As you read previously, Georgia doesn't permit suits for stress (with no physical injury).
To quote an answer you already received elsewhere:
"You can sue for anything. However, if your suit says what you said in your post, expect that your case would be dismissed, and that you would likely be ordered to pay court costs and the school's legal fees for something that frivolous."
My condolences. Your post is a reminder why everyone needs a will. Without a will fairness and a person's wishes are ignored and it's up to state law.
The answer depends on what state your father was in, and also how things were titled (such as joint bank accounts and real estate). In some cases in Georgia the wife may get the entire estate between years support and joint assets. In others, you may be entitled to inherit as much as 1/4 of the estate.
Time matters as there are...
Get a very good criminal lawyer. You may need him or her.
And STOP posting about this on the internet. The question you posted is now on the public internet where police and prosecutors can see it and use your statement as an admission of a crime. That was very unwise. See a lawyer and stay quiet.
There's no way to guess at settlements without knowing the strength of liability by the defendant, what insurer is involved, and details of your medical care. The one thing that is certain is that injured persons without attorneys average getting about 70% less than claimants with counsel. You really need counsel ASAP.
Oral (nuncupative) wills used to be permitted under the pre-1998 code in Georgia, but are no longer permitted, so the language of the will is what matters.
Having said that, there may be some situations where all the heirs agree to do something different than what is in the will and a lawyer may find a way to do it. This is not necessarily simple (or even appropriate in some cases) and needs to be discussed between the executor and the lawyer he retains.
Start with a local lawyer. Your house may or may not already have a right of survivorship. Depending on what the will says, and what the deed says, and your tax situation, you may be doing a probate, a years support case, both, or, in rare cases, almost nothing.
Every day that you wait to hire a lawyer and each time you talk to the adjuster you lose value in your claim. You also lose each time you delay treatment, as the insurer uses that as evidence you are not hurt. You need to go back to the doctor and you need to see a lawyer immediately.
