When parents are injured as the result of someone else’s negligence they have personal injury claims. It is quite possible that their spouses (or in some cases their domestic partners) have loss of consortium claims (basically, for the loss of at least part of the relationship) with a loved one.
The children of the injured parent are often overlooked. But children, and even stepchildren, may bring these claims. If a parent is seriously injured, the claims belonging to the children should be given consideration.
You should contact a personal injury attorney for answers to your questions.
