Requirements vary by document type, and by state
There is no single set of rules that applies to all estate planning documents. Each document type has its own validity requirements, and those requirements vary by state. A will valid in Texas may be invalid in Illinois. A healthcare directive compliant in California may miss mandatory Illinois language.
This is the core problem with generic online templates: they don't account for the specifics of your state.
Will requirements in Illinois
Under 755 ILCS 5/4-3, an Illinois will is valid when:
- The testator is 18 or older (or legally emancipated)
- The testator is of "sound mind and memory"
- The will is in writing
- The testator signs the will (or directs another to sign in their presence)
- Two credible witnesses sign in the testator's presence and in each other's presence
- Each witness attests that the testator appeared of sound mind and under no constraint
Illinois does not require notarization for a basic will, but a self-proving affidavit (which does require notarization) makes probate easier by eliminating the need for witness testimony.
Trust requirements
A revocable living trust is created when the grantor signs the trust document. Illinois does not require witnesses or notarization for a trust to be valid, but as a practical matter, most trusts are notarized because they're often recorded alongside real estate deeds.
More importantly, a trust must be "funded" to work. An unfunded trust is a valid legal document that controls nothing. Every asset you want to pass through the trust must be re-titled into the trust's name.
Financial Power of Attorney requirements
Under the Illinois Power of Attorney Act (755 ILCS 45/2-5), a Financial Power of Attorney must be signed before two witnesses and acknowledged before a notary public. The agent named in the document cannot serve as a witness.
Healthcare Directive requirements
An Illinois Healthcare Power of Attorney (755 ILCS 45/4-10) requires the signature of the principal and two witnesses. The witnesses cannot be: the principal's agent, a healthcare provider, an employee of a healthcare provider, or an heir or beneficiary.
Common ways documents become invalid
- Wrong number of witnesses (Illinois wills require two; one is not enough)
- A beneficiary serving as a witness (can void or reduce that beneficiary's gift)
- Handwritten amendments without proper witnesses
- Missing execution block (the attestation clause at the end of the will)
- Blank placeholders left unfilled in a template
- Using a form designed for a different state
