A will is the instruction that takes effect when you die. It names who inherits what passes through your estate, who administers it, and — for parents — who you nominate to raise your children.
What a will decides
Three things, and they matter in this order for most families.
Who inherits the property that passes through your estate, and in what shares
Who serves as personal representative and administers the estate
Who you nominate as guardian for minor children
What a will does not do
It does not avoid probate — it directs how probate comes out. It does not override a beneficiary designation on a retirement account or life insurance policy. It has no effect at all while you are alive, which is why powers of attorney sit alongside it.
Execution matters as much as drafting
Florida has specific requirements for how a will must be signed and witnessed. A perfectly drafted will that was executed incorrectly can fail. A self-proving affidavit signed at the same time saves your family from tracking down witnesses years later. Remote online signing is permitted, subject to the statutory requirements.
