Wills are not expensive, and a letter is much more difficult to deal with. So get a will. Don't go half way when your kids are at stake. Texas has very modern and streamlined will probate, so the things you may have heard in the past, don't apply in Texas. It is easy. All sorts of things can go wrong if it is just a letter.
He has a workers compensation claim and may have a third party personal injury claim. He should hire a personal injury lawyer to handle his case. He should not talk to the other sides insurance company until he talks to a lawyer.
Without an attorney you can expect to either have the claim denied or a low ball offer. You can hire an attorney on a percent fee, and the attorney will do the negotiating. The delay in treatment will be an excuse the insurance company will use to deny the claim, but a lawyer will know how to respond.
DO NOT SIGN!! There is no such law. Your husband should also not sign until you have at least talked to a lawyer. If the settlement is OK, the lawyer will tell your husband how to handle the release. The fact that your husband returned to work may or may not mean the settlement he is being offered is good. Talk to a lawyer board certified in personal injury law by the official Texas agency--the Texas Board of Legal Specialization. Look at my profile and call my office for an appointment....
I am not sure of your question. I think what you are asking is whether all records have to be produced or just the reports. The answer is usually all records, but the court may order certain limits and protections under certain circumstances. If you are trying to do this without an attorney, you are in way over your head. You just don't have the experience you need to be able to respond to what the other side is doing. If you try to go without a lawyer, you are going to lose 99% of the...
If you were hurt in the collision get medical treatment and then a lawyer. If not, the easiest thing to do is contact your own insurance company and let them do all the work to get your property damage paid.
I assume this is a workers compensation claim. He needs to contact the department of insurance workers compensation division and complain about the doctor. You haven't really given many facts. Breach of trust is not a fact. But there is probably no separate claim against the Dr. Since what the doctor says will only effect the compensation claim, that is where the inaccuracy needs to be dealt with.
Do not talk to the other side's insurance company. If it is only a property damage claim, your insurance will take care of it. If you were hurt, go to a doctor and make sure you get medical care. Also, hire a board certified personal injury law specialist to assist you. The fee will be a percent, so you don't have up front costs.
What do you mean by "liability reversed 1-2yrs?" What are your damages? You say your insurance accpted fault and paid out under collision. Collision is paid to you, not the other side, so it is unclear what you mean by "paid out"--paid to you or the other driver? If to the other driver, it would not be collision, but liability, in which case it is your insurer which is out the money, not you. So please start over and clarify.
