AI Legal Documents in Pennsylvania

Online legal services and AI tools are increasingly used to draft wills, form LLCs, prepare deeds, and handle estate planning. Some of these tools produce decent templates for simple situations in simple states. Pennsylvania is not a simple state. Its inheritance tax system, its Orphans' Court procedures, its POA acceptance requirements, and its real estate transfer tax calculations are materially different from the majority of U.S. jurisdictions, and AI tools trained on national data routinely get Pennsylvania-specific requirements wrong.

Here are the specific errors I see most frequently:

Wills & Estate Planning

Self-proving affidavit failures. A valid Pennsylvania will must be in writing and signed by the testator at the end (20 Pa.C.S. § 2502), but every will must be proved at probate by the oaths or affirmations of two competent witnesses (20 Pa.C.S. § 3132). A self-proving affidavit under 20 Pa.C.S. § 3132.1 satisfies this proof requirement automatically, letting probate proceed without tracking down those witnesses later. The Bucks County Register of Wills uses the statewide form prescribed by the Supreme Court. AI-generated wills frequently omit the self-proving affidavit entirely, include one in the wrong format, or merge the attestation clause and affidavit into a single paragraph that may not be accepted. The result: your executor has to locate the original witnesses and bring them to Doylestown to testify, or file a petition with sworn affidavits of witnesses, which adds cost and delay.

Inheritance tax blind spots. Most AI tools are trained primarily on federal estate tax rules (the multimillion-dollar exemption, the unlimited marital deduction). Pennsylvania's inheritance tax is a completely separate system. It applies to every estate regardless of size, at rates of 0% (spouse), 4.5% (lineal descendants), 12% (siblings), and 15% (everyone else). When an online tool drafts an estate plan, it typically ignores PA inheritance tax entirely or incorrectly states that small estates are exempt. There is no small-estate exemption from PA inheritance tax (though a $3,500 family exemption is deductible, and transfers to surviving spouses are taxed at 0%). A $50,000 estate passing to a sibling owes $6,000 in state tax. This is something nationally-focused tools routinely miss.

Common-law marriage misinformation. Online tools regularly tell Pennsylvania users that common-law marriage exists in the state. It does not. Pennsylvania abolished common-law marriage effective January 1, 2005 (23 Pa.C.S. § 1103). Only common-law marriages established on or before January 1, 2005 are recognized. Online-generated estate plans sometimes assume a long-term partner will inherit as a spouse. Under current PA law, an unmarried partner inherits nothing through intestacy, regardless of how long the relationship has lasted.

Trust templates that miss PA taxation. Most states do not tax trust assets at the state level. Pennsylvania does. Transfers to irrevocable trusts trigger inheritance tax at the time of transfer (or at death, depending on the trust type). Revocable trusts are included in the taxable estate. Online trust templates almost never address PA inheritance tax implications, often creating structures that trigger unnecessary tax liability or fail to take advantage of the spousal exemption and charitable deduction.

Powers of Attorney

Generic "durable" language that banks reject. Under 20 Pa.C.S. § 5608.1, a third party (bank, brokerage, title company) is required to accept a valid POA, but in practice, institutions routinely reject POAs that do not specifically enumerate the powers the agent is trying to exercise. Online-generated POAs typically use broad, generic language ("all financial matters") instead of the specific enumerated powers under 20 Pa.C.S. § 5602. The result: your agent arrives at the bank with a perfectly "valid" POA and is turned away because the document does not specifically authorize the transaction. My POAs include all enumerated powers under § 5602, the hot powers under § 5601.4 (gifting, beneficiary changes, self-dealing), and institution-specific language I know Bucks County banks accept.

Business Formation

LLC formation that skips Pennsylvania requirements. AI tools and online formation services will file your Certificate of Organization with the PA Department of State for $125. What they typically do not tell you: Pennsylvania requires an annual report ($7 filing fee, due by September 30 each year for LLCs). This requirement began in 2025, with a transition grace period covering the 2025 and 2026 report years. Starting with the 2027 report year, missing it can lead to administrative dissolution of your LLC (six months after the due date). They also do not register you with the PA Department of Revenue for tax filing purposes, do not advise on the annual Corporate Net Income Tax return requirement, do not address the Capital Stock/Franchise Tax (now repealed but relevant for older entities), and do not prepare an operating agreement , the single most important document for a multi-member LLC.

Real Estate

Transfer tax calculations that ignore CLR factors. Pennsylvania's realty transfer tax is calculated on the higher of the sale price or the computed fair market value , which is the assessed value multiplied by the Common Level Ratio factor. In Bucks County, the current CLR factor is 17.86 (2026 to 2027). AI tools calculating transfer tax invariably use only the sale price, potentially understating or miscalculating the tax. For property transfers between family members at below-market prices, this is a particularly expensive error.

Deed forms missing required certifications. Every deed recorded in Bucks County must include a Uniform Parcel Identifier (UPI), the complete legal description, and a certification of residence under 16 P.S. § 9781. A Statement of Value (REV-183) is required only when a transfer-tax exclusion is claimed or when the deed does not state the true consideration (61 Pa. Code § 91.112(b)); it is not required on every deed. AI-generated deeds routinely omit one or more of these requirements. The Recorder of Deeds will reject the deed; that is a $10.00 rejection fee, and you have prepaid the $82.75 recording fee and the transfer tax on a document that cannot be filed.

When AI Tools Are Useful vs. Dangerous

AI legal tools have legitimate uses: initial research, understanding basic concepts, generating first drafts that a lawyer then reviews and revises. The problem is not that they exist. It is that people use them as final products instead of starting points. An online-generated will is not reviewed by anyone who knows that Bucks County ROW requires a specific affidavit format. An online LLC filing is not set up by anyone who knows about the annual report requirement. An online-drafted deed is not reviewed by anyone who checks the CLR factor.
