For example, if you wanted to learn something about the history of 16th century Britain, you would be unlikely to learn very much by asking a historian who specializes in the Roman Empire. You would want to ask a historian who specializes in English history. Even better would be asking someone who only studies 16th century Britain.
A similar need for specialization is even more obvious, when you think about your health.
If you need heart surgery, you would not seek the services of an ear, nose and throat specialist. You would not even want a neurosurgeon. You would want a cardiac surgeon.
The same thing is true with legal matters and estate planning, as the Norman Transcript points out in "The right attorney is needed for wills and estate planning."
Estate planning is a complicated and specialized legal field.
Only attorneys who have dedicated their lives to studying the field can be guaranteed to give you the services that you need. You might know someone who is excellent in criminal law or who excels at writing contracts. While he or she might even be willing to help you with your estate planning, you would be better off going to an estate planning expert.
Many avoidable mistakes are made when people do not seek out the services of attorneys who specialize in estate planning. Do not let those mistakes happen with your estate plan.
