Thanks for responding.
A slip in fall case where the cause of the fall was a cracked pavement can be very very difficult to prove. In your case, you have to show that you are not only injured (which might be problem since you've been treated and released already), but also that the crack in the pavement was the result of negligence by Wal-Mart.
I've sued Wal-Mart several times and can tell you that they they are not an easy company to sue and do not like to settle. So unless you have permanent serious injuries, this probably is not a good case to go forward on. If you do have permanent and serious injuries, then you need to go see a Plaintiff's/personal injuiry attorney in Texas.
However, if you want to simply present the claim yourself (which does not have a high likelihood of success), you will need to gather any hospital bills or other expenses you incurred because of the fall, and any missed time at work which caused you a financial loss, and submit this with a letter to Wal-Mart Legal Department at: 702 SW 8th Street, Bentonville, ARNNN-NN-NNNN/p>
The letter would state "I slipped and fell on cracked payment at the Wal-mart Distribution Center in Cleburne, TX on _______ (date). I was injured as follows ________________ (describe the injuries). WalMart is responsible for correcting all hazards such as this under premises liability law in Texas. The cracked side walk was indeed premises defect, and as a direct result of Wal-Mart's negligence, I have permanent and serious injuries. I demand _____________(amount of money) to settle my claims. If I do not receive payment, I will file a lawsuit
Please let me know if you have further questions.
