You can use a website or create your own will in Florida, but we find that some people do not create valid wills, or create wills that do things other than what they want. We only charge $200 for a will so an online will does not save very much considering the risks.
If you want to create your own will be sure that you sign the will at the end and in front of two witnesses. There are benefits to using a self proving affidavit, but one is not required under Florida law. Of course, most lawyers will include a self proving affidavit with the will that they prepare for you.
Many online wills or wills that individuals try to create do not include provisions for things that happen routinely. Some examples are a named person dies simultaneously, shortly after you, or before you. An improperly drafted will could expose your belongings to their creditors in such a case.
