Short answer
Most wills use a residue clause so you don’t need to list every single asset. But you can make specific gifts and keep a separate asset list (like in LifeVault) to help your executor.
Practical tips
- Use specific gifts only where you really mean it (e.g., “car to X”).
- Keep an up-to-date asset list and account info; avoid including credentials in the will itself.
- Review when major assets change.
