Making a valid will in Pennsylvania takes less than most people expect: be at least 18 and of sound mind, put it in writing, and sign at the end (20 Pa.C.S. §§ 2501–2502). No notary is required, and for a typical typed will, no witnesses are required for validity — though you'll want two witnesses and a self-proving affidavit anyway, for reasons this guide explains. The requirements are the easy part. The traps — signing formalities, what a will can't control, and the assets that quietly bypass it — are where estates go wrong.
Creating a will is the foundation of protecting your family. Without one, Pennsylvania's intestacy statute decides who inherits — and its formula (a surviving spouse often shares the estate rather than inheriting it all) surprises nearly everyone. Here is the complete picture: what Pennsylvania actually requires, the step-by-step process, what it costs, and the mistakes we see in probate when wills are done wrong.
What Pennsylvania Actually Requires
Under 20 Pa.C.S. §§ 2501 and 2502, a valid Pennsylvania will requires:
- Age and capacity. You must be at least 18 years old and of sound mind — broadly, you understand what you own, who your family is, and what the will does.
- A writing. Typed or handwritten. Oral wills are not recognized in Pennsylvania.
- Your signature — at the end. The placement rule has teeth: text appearing after the signature is generally not given effect. A "quick addition" scribbled below your signature line usually accomplishes nothing.
That's the core list — no notary required, and for a typical typed will, no witnesses required for the will to be valid. But before you close this tab and sign something at your kitchen table, read the next section, because the witness rule is where most online explanations (and plenty of DIY wills) go wrong.
The Witness Rule Most Websites Get Wrong
Two different moments matter, and they have different rules:
- At signing (validity): a typed will signed by you needs no witnesses to be valid. The exceptions: if you sign by mark, or someone signs for you at your direction, Pennsylvania requires two witnesses present at signing.
- At probate (proving the will): after your death, the Register of Wills generally requires two witnesses to verify your signature before admitting the will. If your will was signed alone in a drawer, your executor has to find people who can credibly prove your handwriting — years or decades later.
The fix for this gap is the self-proving affidavit under 20 Pa.C.S. § 3132.1: at your signing, you and two disinterested adult witnesses sign a short sworn statement before a notary. That affidavit lets the will be admitted to probate with no witness testimony at all — nobody to locate, nobody who has died or moved away, no delay.
So the practical execution standard — the one we use for every will we prepare — exceeds the bare legal minimum: testator signs at the end, two disinterested witnesses sign, notary completes the self-proving affidavit, all in one sitting. Ten extra minutes at signing saves your family weeks at probate.
Making Your Will: The Seven Steps
1. Inventory what you own — and how it's titled
List real estate, accounts, retirement plans, life insurance, business interests, vehicles, and meaningful personal property. Note how each is owned and whether it has a beneficiary designation — because that determines whether your will controls it at all (see below).
2. Decide who inherits — including backups
Name your beneficiaries and contingent beneficiaries. What if a child predeceases you — does their share go to their children or to your surviving children? Templates skip these questions; probate disputes are made of them.
3. Choose your executor
Your executor shepherds the estate through the Register of Wills: filings, creditor notice, the inheritance-tax return, distributions. Choose someone organized and trustworthy, name an alternate, and — kindness matters — let them know what the job involves.
4. Name a guardian for minor children
For parents, this is often the single most important clause in the will — the person who raises your children if both parents are gone. Name an alternate here too.
5. Draft the document
This is where the online-template risk concentrates: a form that looks valid but misses Pennsylvania's execution details, contradicts your beneficiary designations, or ignores contingencies you didn't know to plan for. Whether you use an attorney or not, the questions in steps 1–4 deserve real answers before anything is signed.
6. Execute it correctly — the ten-minute ceremony
Sign at the end, before two disinterested adult witnesses (people who don't inherit under the will), who then sign, with a notary completing the self-proving affidavit — everyone present in one sitting. Done this way, your will walks into probate without needing anyone's testimony.
7. Store the original where it can be found
The Register of Wills wants the original — a photocopy raises a presumption you revoked the will. Use a fireproof safe at home or your attorney's safekeeping; avoid a bank safe-deposit box unless someone else has access rights. Tell your executor exactly where it is.
What a Will Cannot Do
The most expensive misunderstanding in estate planning: a will only controls probate assets. It does not override:
- Beneficiary designations on life insurance, IRAs, 401(k)s, and POD/TOD accounts — the designation wins, even if your will says otherwise
- Jointly owned property with survivorship rights, which passes automatically to the surviving owner
- Trust-held assets, which follow the trust's terms
A will also does nothing for incapacity — that's the job of financial and healthcare powers of attorney, which every adult should sign alongside a will. And a will does not avoid probate or Pennsylvania inheritance tax — a will goes through probate, and the tax applies either way (estimate yours here). If probate avoidance matters to your situation, that's the will-versus-trust conversation.
One more limit worth knowing: Pennsylvania law protects a surviving spouse with an elective share — a spouse generally cannot be fully disinherited by a will alone.
What It Costs
- DIY or online: cheap up front; the risks are execution errors, template gaps, and conflicts with beneficiary designations — failures that surface only at probate, when they can't be fixed. We've written honestly about where these services go wrong.
- An attorney-drafted will is typically part of a package — will, financial power of attorney, healthcare directive — because those documents work as a set. At our firm, the fee is agreed up front, in writing, before any work begins. For most families the cost is comparable to a car repair — for a document family will rely on for decades.
When to Update It
Review your will after marriage, divorce, a birth, a death in the family, a major change in assets, or a move into or out of Pennsylvania — and every three to five years regardless. Divorce deserves special mention: Pennsylvania statutes generally make provisions favoring a former spouse ineffective, but the statutes have gaps and exceptions — update the documents; don't rely on the default. Small changes can be made by codicil, but with modern drafting it's often cleaner to sign a fresh will.
Mistakes That Sink Wills in Probate
From our probate practice, the recurring ones:
- Writing on the will after signing — cross-outs and margin notes don't amend a will; they invite challenges.
- Text after the signature — remember the sign-at-the-end rule; post-signature additions generally fail.
- Losing the original — a missing original can mean the will is presumed revoked.
- Beneficiary designations contradicting the will — the designations win, and nobody checked.
- No contingent beneficiaries or alternate executor — one death out of order unravels the plan.
- Interested witnesses and sloppy signings — avoidable with the ten-minute ceremony done right.
The Bottom Line
Pennsylvania makes a valid will easier than almost any state — and makes a reliable one exactly as hard as everywhere else, because the reliability lives in the details: the execution ceremony, the coordination with beneficiary designations, the contingencies, the storage. Get those right and your family inherits a plan instead of a project.
