A number of years ago, my spouse and I decided to create a will as we were worried about our daughter not being taken care of if something bad happened.
After investigating options to do it ourselves, we decided to pat a lawyer $1500+ and ended up very glad we did. There were serious considerations that hadn't even crossed our minds. It also was built such that it was applicable even after she reach adult age.
My recommendation is to get a lawyer, especially if you have dependents, real estate, or other substantial investments.
