Areas of Practice






YOUR ADVOCATE FOR A NEW LIFE. Divorce, called Dissolution of Marriage in Montana, can be overwhelming regardless of who initiated the proceeding. Where will you live? What about the kids? Child Support? Who gets what? How much is this going to cost? Although each divorce is different we have the knowledge and experience to answer all of your questions and develop a strategy for protecting the best interest of you and your children.


Have you or a loved one been injured in an accident due to someone else’s negligence? If so, there are numerous medical, personal, and financial issues you’re forced to deal with. It can be a daunting time. Once you file a claim, an adjuster will contact you. Although this person may appear to be on your side, he, ultimately, does not have your best interests in mind. This person works for the Insurance Company and is primarily interested in minimizing payouts. The attorneys at Hedman, Hileman & LaCosta are on your side and will make sure that you receive fair and just compensation for your injuries. What is fair and just compensation? What is your case worth? These are common questions. The worth of a personal injury lawsuit is based upon the quantifiability of the damages incurred. These damages are measured in terms of the amount of money lost (and anticipated to be lost in the future) on medical bills, wages, earning capacity, and pain and suffering. There is no black-and-white answer to how much a case may be worth., as factors such as health history, mitigation of damages, and the patient’s compliance regarding accident-related medical treatment can increase or decrease an award significantly.
