This is an option.
If all you care about is price then it's a great option.
If you care about personal service then it is not.
Here's what I mean:
Let's say you buy a Will through a website because they have a really low price.
Now it's four years later and you have a question.
Who are you going to call? The website?
Do they even offer that service? I do.
My estate planning clients are always free to call with follow-up questions at any time.
Will the website be around in four years? I will!
Even if I'm not you can always find another attorney!
See my Estate Planning 101 Article here:
The same reason you would hire any other professional. Chances are, we've seen and handled your situation before and know how to help you!
Simply put, estate planning answer the question of what happens to "your stuff" after you die.
Why do you go to a doctor?
Why do you go to a dentist?
I'm guessing it's because you think they have certain knowledge and skills that you do not have. They probably do. That's how the world works.
Speaking for myself, I do not know how to fix a cavity or perform a root canal. Or how to set a broken bone, diagnose a sick person or any of the other things doctors do.
I hire people who know about these things to help me when I have these problems.
You should too.
