Most Pennsylvania probate mistakes aren't dramatic. They're an executor doing something reasonable-sounding at the wrong time. The costliest ones: distributing money during the one-year advertisement window (that's personal liability), skipping the estate advertisement that starts the window in the first place, missing the nine-month inheritance-tax deadline (or the 5% discount at three months), and paying whoever calls loudest instead of following the statutory priority order. Here are the twelve mistakes we see most, and the statute behind each.
Serving as an executor is mostly a job of sequence: the right steps, in the right order, on the right clocks. The mistakes below are the ones that actually cost money, sometimes the estate's, sometimes the executor's own. If you recognize yourself in one of them mid-estate, none of these is unrecoverable; the fix is easier the earlier it starts.
1. Distributing Assets Too Early
The single most dangerous mistake. Under 20 Pa.C.S. § 3532, distributions made within one year of the first complete advertisement of the estate are made at the personal representative's risk. Hand your sibling their share in month four, watch a valid creditor claim surface in month nine, and the money to pay it may come out of your pocket. Most estates wait out the year for exactly this reason. It's why even a cooperative Pennsylvania estate takes nine to twelve months.
2. Skipping (or Delaying) the Estate Advertisement
The one-year protection clock doesn't start until the estate is properly advertised under 20 Pa.C.S. § 3162: once in a newspaper of general circulation and once in the county legal journal, for three successive weeks. Executors who skip the advertisement to save a few hundred dollars leave the claims window open indefinitely. Advertise immediately after appointment; it's the cheapest liability protection in the entire process.
3. Commingling Estate and Personal Funds
The estate is a separate legal entity and needs its own bank account, opened with the estate's EIN. Depositing estate checks into your own account (even temporarily, even with perfect intentions) blurs the accounting, invites suspicion from beneficiaries, and is the classic first fact in a surcharge petition. One estate account, every dollar in and out through it, from day one.
4. Paying Debts in the Wrong Order
Pennsylvania sets a strict payment priority in 20 Pa.C.S. § 3392: administration costs first, then the family exemption, funeral expenses, medical expenses of the last illness, rent, and only then general creditors. An executor who pays a persistent credit-card collector before the funeral home, and then runs short, can be personally responsible for the misordered payment. In a solvent estate this rarely bites; in a tight one, the order is everything.
5. Missing the Inheritance-Tax Clocks
Two dates matter. The Pennsylvania inheritance-tax return (REV-1500) is due nine months from the date of death, with interest accruing after. And a payment made within three months of death earns a 5% discount on the tax paid. On a $500,000 taxable estate at the 4.5% child rate, that discount is over $1,100 for writing a check early. Executors lose the discount by waiting for perfect numbers; a reasonable estimated prepayment captures it.
6. Treating Non-Probate Assets Like Estate Property
Joint accounts with survivorship rights, POD/TOD accounts, life insurance and retirement accounts with named beneficiaries, and assets in a funded trust pass outside the will. An executor who gathers them into the estate account creates a genuine mess, and one who distributes them under the will's terms creates a worse one. (They may still matter for inheritance tax, which is a separate question from who receives them.) When in doubt, classify first, move money second.
7. Selling Real Estate Without Checking Your Authority
Whether an executor can sell the house without court involvement depends on the will's language and the circumstances. Selling first and checking later can cloud the title you're trying to convey and put the proceeds in dispute. Confirm the authority, get the tax picture straight (the sale interacts with the inheritance-tax valuation), and paper the transaction properly. Deed work in an estate is its own discipline.
8. Overlooking the Family Exemption
Under 20 Pa.C.S. § 3121, the surviving spouse (or if none, minor children) may claim up to $3,500 from the estate ahead of creditors. It's not automatic; it has to be claimed. In a comfortable estate it's a modest benefit. In an insolvent one, it may be the only thing the family keeps, and forgetting it is the kind of oversight that's painful precisely because it was free.
9. Guessing on the REV-1500
The inheritance-tax return rewards care: rates turn on each beneficiary's relationship to the decedent (0% spouse, 4.5% children and parents, 12% siblings, 15% others), some assets are exempt, deductions matter, and valuations get reviewed by the Department of Revenue. A guessed return draws assessment notices and delay; an amended-return cycle can add months to the estate. Get it right once. Here's how the REV-1500 actually works.
10. Keeping No Records
Every estate ends with an accounting, formal or informal, and the accounting is only as good as the records behind it. Executors who administer from memory spend the final months reconstructing a year of transactions from bank statements, and every gap reads as a question mark to beneficiaries. A simple ledger kept contemporaneously (date, amount, purpose, category) turns the final account from an ordeal into an afternoon.
11. Taking Fees Casually
Pennsylvania executors are entitled to reasonable compensation, but "reasonable" is judged after the fact, fees are taxable income to you, and helping yourself to compensation early and informally is a reliable way to turn beneficiaries into adversaries. Decide the fee deliberately, document the work behind it, and take it at the end with the beneficiaries' eyes open. (Sometimes waiving a fee is the smarter move, particularly when the executor is also the main beneficiary and the fee would just convert a 0% or 4.5% inheritance into ordinary income.)
12. Going Silent
Almost every estate dispute we're brought into shares one feature: beneficiaries who heard nothing for months and assumed the worst. Pennsylvania requires formal notice at the start, but the legal minimum won't protect you from suspicion. A short update at each milestone (estate opened, advertisement running, tax return filed, waiting out the claims year) costs minutes and prevents the challenge that costs the estate thousands.
The Pattern Behind All Twelve
Notice what these have in common: none requires bad intent. They're all a conscientious person acting on instinct (pay people quickly, keep things simple, help family now) in a process where the instincts are wrong and the sequence is statutory. That's the real case for having counsel handle the administration: not that the steps are impossible, but that the expensive mistakes all feel reasonable at the moment you make them.
