Pennsylvania Lien Waiver Forms — Generate in 60 Seconds
Generate Pennsylvania lien waivers that comply with the Mechanics' Lien Law of 1963 (49 P.S. 1101 et seq.) and the Contractor and Subcontractor Payment Act (CASPA). Pennsylvania does not prescribe mandatory form language, but 49 P.S. 1401 strictly limits when waivers can be signed on nonresidential projects. All four waiver types available with free preview.
Which Type Do You Need?
Pennsylvania uses the standard 4-type framework (conditional/unconditional x progress/final). The key PA rule: on nonresidential projects, advance waivers are void under 49 P.S. 1401. A waiver is only enforceable "in consideration for payment" and "only to the extent that such payment is actually received." Conditional waivers align naturally with this rule.

No mandatory statutory form
Pennsylvania does not prescribe specific waiver form language. 49 P.S. 1401 regulates when and how waivers can be given, not the exact form they must take.
Advance waivers VOID on nonresidential
49 P.S. 1401 (Act 52): waivers before payment on nonresidential projects are "against public policy, unlawful and void." Only valid to the extent payment is actually received.
Residential exception (3 stories or less)
On residential projects of 3 stories or less, contractors may waive lien rights before work begins via a Stipulation Against Liens filed with the prothonotary.
Notarization NOT required
Lien waivers do not need to be notarized in Pennsylvania. However, a Stipulation Against Liens must be filed and indexed with the prothonotary.
6-month lien filing deadline
All claimants must file within 6 months after completion of work (49 P.S. 1502). Notice to owner required within 1 month of filing.
CASPA payment protections
The Contractor and Subcontractor Payment Act (73 P.S. 501 et seq.) provides non-waivable payment rights. Contract clauses that conflict with CASPA are void.
Pennsylvania Lien Waiver Legal Requirements
Pennsylvania's approach to lien waivers centers on timing, not form. The Mechanics' Lien Law of 1963 (49 P.S. 1101 et seq.) does not prescribe mandatory waiver language, but 49 P.S. 1401 — added by Act 52 (effective January 1, 2007) — makes advance waivers on nonresidential projects "against public policy, unlawful and void." A waiver is enforceable only "in consideration for payment for the labor or materials provided and only to the extent that such payment is actually received." For subcontractors (sub-tier parties), an exception exists if the GC has posted a payment bond. On residential projects of 3 stories or less, contractors may waive lien rights in advance by filing a Stipulation Against Liens with the prothonotary (49 P.S. 1402). Separately, the Contractor and Subcontractor Payment Act (CASPA, 73 P.S. 501 et seq.) provides additional payment protections that are largely non-waivable by contract. The 2018 CASPA amendments strengthened these protections further, including limits on retainage withholding and the right to suspend work during payment disputes.
Recent Law Changes
- Act 142 (2014, implemented 2017): created the State Construction Notices Directory for projects over $1.5M. Subs must file Notice of Furnishing within 45 days or risk losing lien rights.
- CASPA amendments (Act 27, effective October 2018): added non-waivable payment protections, right to suspend work during payment disputes, and limits on retainage withholding beyond 30 days after final acceptance.
Pennsylvania Conditional Progress Waiver
What It Is
Custom template waiving lien rights for a progress payment, conditioned on receipt and clearance of payment. Aligns with 49 P.S. 1401's requirement that waivers only be effective to the extent payment is received.
When to Use
When submitting a pay application for a progress draw and you want lien rights protected until the check clears.
Key Legal Points
- No statutory form — our template is designed for Pennsylvania compliance.
- Conditional on payment: effective only upon receipt and clearance of the specified payment amount.
- Aligns with 49 P.S. 1401 — waiver is enforceable only to the extent payment is actually received.
- Retainage preserved — template explicitly excludes retained amounts from the waiver.
- Change orders and disputed extras preserved as exceptions.
- CASPA payment protections remain intact regardless of the waiver.
Tips
- The conditional structure is the safest approach under Pennsylvania law — it tracks the 49 P.S. 1401 requirement perfectly.
- Include the period of work covered and all payment details.
- Keep copies of pay applications referenced in the waiver.
- CASPA gives you 14 days to receive payment from the tier above after they receive theirs.
Pennsylvania Unconditional Progress Waiver
What It Is
Immediately waives lien rights for the covered progress payment upon signing. No condition precedent — effective the moment you sign.
When to Use
Only after the progress payment has been received AND cleared your bank. Not merely deposited — cleared.
Key Legal Points
- Immediately effective upon signing — no safety net if payment fails.
- Under 49 P.S. 1401, if signed before actual receipt of payment on a nonresidential project, the waiver is void.
- Covers only the specified progress payment — retainage and future payments excluded.
- CASPA protections remain intact.
Warning
On nonresidential projects, signing this before actual payment is received makes the waiver void under 49 P.S. 1401. But proving that requires litigation. Use a conditional form until payment clears — it's safer.
Tips
- Only sign after payment has fully cleared your account.
- Compare the waiver amount to the actual cleared payment amount.
- If a GC pressures you to sign before payment, point to 49 P.S. 1401.
Pennsylvania Conditional Final Waiver
What It Is
Waives all remaining lien rights on the entire project, conditioned on receipt and clearance of final payment including retainage.
When to Use
When requesting final payment (including retainage) and you want protection until it clears.
Key Legal Points
- Covers ALL remaining work and lien rights on the project.
- Conditional on receipt and clearance of final payment.
- Final payment should include all retainage amounts.
- Under CASPA, retainage must be released within 14 days of receipt by the tier above.
- Any disputed amounts should be listed as exceptions.
- CASPA protections survive the waiver.
Tips
- Ensure the final payment amount includes all retainage — there's no statutory cap on private retainage in PA, so verify the actual amount withheld.
- List any remaining disputes or contested change orders as exceptions.
- CASPA's 2018 amendments limit retainage withholding beyond 30 days after final acceptance unless a written notice of deficiency is issued.
Pennsylvania Unconditional Final Waiver
What It Is
The most consequential waiver. Immediately and irrevocably releases ALL lien rights on the entire project upon signing.
When to Use
Only after ALL payment — including final payment and retainage — has been received and cleared.
Key Legal Points
- Complete and permanent release of all lien rights on the project.
- On nonresidential projects, void under 49 P.S. 1401 if signed before payment is received — but proving this requires litigation.
- No exceptions or carve-outs once signed.
- CASPA protections (payment timing, interest penalties) survive independently of lien rights.
- Most consequential Pennsylvania waiver form — verify every dollar before signing.
Warning
Do not sign with any amounts outstanding. Once signed, this is permanent and irrevocable. If you're on a nonresidential project and haven't been paid, 49 P.S. 1401 theoretically protects you — but enforcing that protection means going to court.
Tips
- This is the final, complete release. Verify every dollar before signing.
- If disputes remain, use a conditional final instead and resolve separately.
- Even after signing, your CASPA rights (interest penalties, attorney fees) remain available for any unpaid amounts.
Common Pennsylvania Lien Waiver Mistakes
- 1
Signing advance waivers on nonresidential projects
49 P.S. 1401 makes these void — but many GCs still request them. A waiver is only enforceable to the extent payment is actually received. Use a conditional waiver instead.
- 2
Not filing a Notice of Furnishing on large projects
If the project costs over $1.5M and the owner filed a Notice of Commencement with the State Construction Notices Directory, you must file a Notice of Furnishing within 45 days of starting work. Miss this deadline and you could lose your lien rights entirely.
- 3
Missing the Notice of Intent before filing a lien
Pennsylvania requires subs to serve a Notice of Intent on the owner at least 30 days before filing a mechanics lien. You must also file an affidavit of service within 20 days. Skipping either step can invalidate your entire lien claim.
- 4
Confusing lien waivers with Stipulations Against Liens
A Stipulation Against Liens is a recorded document filed with the prothonotary that prevents any liens from being filed — only available on residential projects of 3 stories or less. A lien waiver is a separate document exchanged during payment. Different tools, different rules.
- 5
Not knowing about CASPA's non-waivable protections
CASPA (73 P.S. 501 et seq.) provides payment protections that can't be waived by contract. Even if you sign a lien waiver, your CASPA rights to prompt payment, interest penalties, and the right to suspend work remain intact.
