What is estate planning and should I be doing it??

What kind of professional would someone have to see for Estate Planning and is it expensive? I am thinking about doing this myself.

Thanks Harley Hog. I am on a pretty tight budget right now, but I am still going to look into this. It's important for me and my family.

I do not think I need to provide a vast definition for estate planing. Estate planning is a process. It involves people, your assets and the various forms of ownership and title that those assets may take. It addresses your future needs in case you ever become unable to care for yourself.Many people mistakenly think that estate planning only involves the writing of a will. Estate planning, however, can also involve financial, tax, medical and business planning. Therefore keeping a tab on the market can be a very prudent decisions by means of personal finance of newsletters or researching regularly online can be very useful.
