While specific statistics directly measuring "regret" about not having a will are scarce, surveys and studies do indicate that a significant portion of individuals express regret or concern about not having proper estate planning in place, especially after facing a life event like illness or the loss of a loved one.

For example, a 2020 survey conducted by Caring.com found that, while 68% of adults knew that having a will is important, many still delayed creating one. Additionally, older adults, especially those who experienced health scares or the death of a loved one, often express regret for not having taken action earlier to secure their estate planning.

These insights suggest a strong correlation between life events and the realization of the importance of having a will, leading to regret for not having created one sooner.
