You can apply for a personal injury loan online or in person if your lender has a physical location. Depending on the lender you apply with, you may have to undergo a credit check. Similarly, your lender may require certain documents to verify your identity, income, debt, and employment. Once you submit the application with all the appropriate information and documents, you should receive a response soon after. Once approved, some lenders will provide the funds within a couple of hours to a few days.
