Suffering a serious injury due to someone else’s wrongful conduct can be devastating. Pain and suffering, huge medical bills, lost wages and a loss in your ability to function normally are only some of the terrible consequences that can affect your life.

Having a loved one seriously injured or killed by another’s wrongful conduct can be even worse. Loss of companionship, emotional distress and financial hardship are common in this situation.

If you find yourself in either situation described above, it is extremely important to hire an experienced and successful personal injury attorney or wrongful death lawyer right away. Only by doing this can you protect your rights and give yourself the best shot at putting your life back together.  

At Wayfinder Law, we can help you get appropriate medical treatment for your physical and emotional symptoms, keep medical bill collectors at bay, suggest options for paying your living expenses, and provide education and comfort throughout the lawsuit process. We can also ensure that all important evidence is gathered, that all key witnesses are located to support your lawsuit and that all possible valid legal personal injury or wrongful death claims are filed.

Finally, we work to ensure that you are fully and fairly compensated for the damages you’ve suffered, whether that be by settlement or trial.

The sooner you get started, the sooner you’ll get through this. Get in touch with an experienced and successful personal injury attorney today by contacting us.

Estate planning is a way to ensure that your most important wishes are carried out when you die (or at any point during your life that you cannot handle your own affairs).

Common wishes include:

  • Providing financial support for family and loved ones
  • Ensuring proper care for minor children and disabled family members
  • Contributing to charities
  • Maintaining privacy/not having finances made public
  • Protecting assets
  • Having a quick, efficient, and less costly settling of one’s affairs after their death.

Also very important are choices about who will handle your financial matters and medical treatment decisions if you become unable to do so.  

Estate planning is normally carried out through the use of wills, trusts, and specialized probate avoidance planning techniques. 

In essence, the best estate planning attorney ensures their clients’ peace of mind, and we take pride in providing you with this result. 

If you have estate planning needs in Missouri or Illinois, Wayfinder Law is a law firm that welcomes the opportunity to help.  Learn More…

Following the death of a loved one, you shouldn’t have to worry about learning probate law.

Probate is a complicated court process where a deceased person’s last will and testament is “proven,” or determined to be authentic, and the deceased person’s property is distributed according to the terms of the will (after paying valid debts and other expenses).

If the deceased person did not have a will, the court normally will distribute their property to any surviving heirs according to state law (after paying valid debts and other expenses). Of note, hiring a probate attorney is required in most situations. The help of a good probate attorney to guide you through this court process can be priceless.

In most instances, probate is a process best avoided through the creation of a good estate plan, as it can be expensive and normally lasts at lease one year. However, if probate and estate administration is required following the death of your loved one in Missouri or Illinois, we are ready to guide you through the process in a caring, thoughtful and efficient manner.

You can meet with an estate planning attorney in our St. Louis, Missouri, or Belleville, Illinois, office or have your free consultation by phone. Contact us today.
