Up to you. QE provides all possible fields of help to your executor, but you decide how many to fill in.
Most files can be populated with information of immediate value to your executor in 30 - 60 minutes; longer for complex estates.
No need to rifle through files or financial statements. Input the basics of who and what’s involved and add more detail over time. The more information you provide, the faster and easier it will be to settle your estate.
