What are the 4 components of an estate plan

Pour-Over Will

 A legal document that ensures any assets not already placed in a living trust during a person's lifetime are transferred into the trust upon their death. It acts as a backup, directing any unallocated assets to be managed and distributed according to the trust’s terms.

Living Trust
An alternative to a last will, it allows you to choose who will receive your assets after your death. But living trusts also let your family avoid probate court, which can be time-consuming. Usually takes more time to set up and requires ongoing maintenance. 

Financial Power of Attorney
Designates someone to make decisions about your financial affairs if you're unable. This could be because you’re incapacitated, or are simply unavailable due to deployment, travel, or other reasons.
Advance Healthcare Directive
Gives instructions for medical staff about what treatments you want to receive if you can't communicate. It can also appoint someone to make these decisions on your behalf.
