While there are many benefits to having an Estate Plan in place before you pass away, a sound Estate Plan can also protect you while you're still alive. For example, by appointing a Power of Attorney. A Power of Attorney is is a document which allows you to designate a trusted individual to step in and conduct your business and financial affairs on your behalf in the event you are unable to do so.
You might also consider creating a Living Will. A Living Will allows you to express any medical directives and preferences, should you be unable to communicate on your own.
Finally, an Estate Plan can protect you while you're still alive through the appointment of Guardianship Nominations. Appointing a guardian in the event you're unable to take care of your own child ensures that your child never has to go into the custody of strangers. This can be enacted even if you're only unable to care for them on a temporary basis
