How to fill out a lien waiver

A lien waiver is a short document, which is why it gets filled in carelessly. Four identities, one date, one amount, one word, and a signature. Here is what each one does.

The header block

Four identities go at the top and all four have to be right: the claimant (you), the customer you invoice, the owner of the property, and the property itself. People fill in the customer and skip the owner, because the owner is not who pays them. The owner is the one whose title the lien would attach to, which is the only reason the document exists.

Use the legal entity name, not the trading name — “Ironline Mechanical LLC”, not “Ironline”. On the property line, an address is the minimum and a legal description is better; a waiver that cannot be tied to a parcel is a waiver nobody can rely on, including you.

The header fields
Field	What goes in	Common error
Claimant	Your legal entity name	Trading name or a person's name
Customer	The party you contract with	Left blank on lower-tier jobs
Owner	Owner of record	Filled in with the general's name
Property	Address plus legal description	Suite number omitted

The through date

This is the field that decides what you are giving up. Everything furnished on or before it is released; everything after it survives. Set it to the last day of the billing period the payment covers — not today's date, and never a date in the future.

A through date that runs past the period you were paid for is the quiet way subcontractors release unbilled work. If you poured on the 2nd and the application covers through the 31st of the previous month, the through date is the 31st.

Never post-date

A future through date releases work you have not billed, let alone been paid for. If the general asks for one, the answer is no, and the reason is one sentence long.

The amount, and what it does not do

On a conditional waiver the amount is a cap: the release extends only to the extent of that payment. On an unconditional waiver the amount is decoration — the release is complete on signature whatever number is written. That asymmetry surprises people every year.

Match the amount to the net payable after retainage, which is the figure that will actually land. Work it out on the retainage calculator and copy the net line across.

What the amount controls
Waiver	Amount is	Effect if wrong
Conditional	A cap on the release	Under-releases; harmless to you
Unconditional	Descriptive only	No protection at all

Signature, title and the exceptions block

Sign as an authorised officer with your title, not as “the office”. Some states require notarisation and several publish a statutory form that must be followed almost word for word; the state requirements page covers which.

If your form has an exceptions or exclusions block, use it. Disputed change orders, backcharges you do not accept, and stored materials not yet paid for belong there, listed by number. An empty exceptions block is read as “nothing excepted”.
