If you want a quick answer to a simple health question, you might search online. But, if you want customized care, tailored to your exact health situation and patient history, you'll go see a doctor. And if your head hurts, you won't make an appointment with the podiatrist.
The same applies to Estate Planning, and the consequences of poor planning can have a lasting detrimental effect on your loved ones after your passing.
If you want a customized plan made specifically for you, your financial situation, your family, marital status, health wishes, and anything else that is important to you, you'll need an attorney who focuses on comprehensive estate planning. Online forms and fill in the blanks are not a substitute for competent legal advice.
A website can generate a will; an attorney can give you advice; but the right attorney will be able to provide tailored advice and the right legal documents to ensure your wishes are carried out after your passing.
