Can a genealogist guarantee results?

No. No genealogist can guarantee results, because the result depends on whether a record survived, and nobody controls that. What an honest genealogist can guarantee is the search: a written plan, every record checked and listed, a reason for every dead end, and a bill that stops when the paper does. Anyone promising more is selling something other than research.

Why can't a genealogist guarantee results?

Because the record has to exist before anyone can find it. Parish registers, the church's own books of baptisms, marriages and burials, burn and flood. The FAQ on my own pricing page answers it the way I would in person: no honest genealogist can promise you'll reach the 1600s, because records burn, parishes lose books, and some lines end in a true wall.

Others in the field say the same. ICAPGen, the International Commission for the Accreditation of Professional Genealogists, puts it in one sentence on its cost page:

No researcher can guarantee that your family will be found in the records.

The same page adds that sometimes the information can't be found. Genealogy Explained warns readers to be wary of anyone who guarantees they'll solve a brick wall. A brick wall is the point where a line stops because the record naming the next parent can't be found.

Notice what the big firms sell. Legacy Tree Genealogists' FAQ describes a project as hours worked against goals you set, and says their genealogists accomplish as much as they can in the time they have. That's an honest description of a search, not a promise of a result.

What can an honest genealogist promise instead?

Four things, and expect all four in writing before you pay.

1. A standard for the search. The profession's benchmark is the Genealogical Proof Standard, maintained by the Board for Certification of Genealogists. It has five parts: reasonably exhaustive research, complete and accurate source citations, thorough analysis and correlation, resolution of conflicting evidence, and a soundly written conclusion. "Reasonably exhaustive" means the researcher checked every kind of record that could plausibly answer the question, not the first database that returned a hit. Genealogy Explained says plainly that responsible genealogists should always research to that standard.
2. A written trail. Every search, including the ones that came up empty, with the archive, the book and the pages read. An empty search that's written down is evidence, sometimes called negative findings.
3. A reason for every dead end. As Genealogy Explained puts it, a professional should always present enough evidence to explain why they can or can't answer your question. "I couldn't find it" is not a finding. Something like "the parish's baptisms begin in 1812, and the family was there by 1790" is.
4. A scope you can hold them to. Genealogy Explained lists what a written agreement should carry: the research goal, the hours agreed, the total cost and the expected completion date. Mine is written by depth rather than hours, but the principle holds. If it isn't written down, it isn't promised.

Every package I sell lists the research trail, every search and every dead end, as a deliverable on the pricing page. That is the guarantee I can sign: not that the record exists, but that if it does, I'll have looked where it is, and if it doesn't, you'll know where I looked.

What does honest research look like on a real case?

My best example is public, and unsolved. Padre José Nicolás Ballí is the priest Padre Island is named for, and nobody has documented when he was born. The state marker says "sometime in the 1770s," the National Park Service says about 1768, and the statue at the causeway reads "177?". I opened File 001 in August 2026 to find the date. As I write this in October it's still open, and the hunt is being filmed.

The three paths

The one record that would settle it, his baptism, was most likely lost when a flood destroyed Reynosa in 1800. So the plan went around it: the burial books in Matamoros, his 1828 will, and his ordination file in Mexico, because canon law required a baptismal certificate before a man could be ordained.

Two paths worked to the end of their paper

The burial path produced. Reading the register of Nuestra Señora del Refugio page by page, I found his burial entry, which no index points to and no published source cites. It records the parish's highest rites and his cause of death, a stroke, and it showed that the death date in every history book is actually his burial date; the register calls him "el finado," the deceased, five days earlier. That correction went to the Texas State Historical Association and the National Park Service. It did not settle his birth.

The will path closed differently. The original 1828 will is not in the Matamoros archive. The archive answered my inquiry in September 2026: it went missing from the city's holdings decades ago. What survives is a typescript at the Texas General Land Office and a certified copy recorded in Cameron County in 1909. He names his parents in it. The birth year stayed open.

One path still open

The Reynosa marriage register, free online, gave me his signature twice, on marriages he performed in January and February 1807 as interim priest. Canon law set the minimum age for ordination at 24, so a dated page with his signature as a priest puts a documented boundary on a birth year everyone had only guessed at. That's a bracket, not an answer. The answer, if it exists, is in his ordination file in the archdiocesan archive in Monterrey. The archive's director welcomed the research but could not confirm the file survives. Whether the page is there, I don't know.

What that means for the bill

Had this been a client's line on a milestone-billed package, paid in parts as the research reaches 1800, 1700 and delivery, two of three paths would now be documented to their end, one would be waiting on an archive, and the birthdate would still be a question mark. On my terms, billing on a line like that stops at the last milestone reached, and the client keeps everything found: the burial entry, the corrected death date, the signature, the surviving texts of the will, and the trail showing where the paper ran out. A guarantee would have had to invent the rest.

Do I pay if nothing is found?

It depends on how the researcher bills.

With an hourly researcher, yes. You're buying hours, and the clock runs the same whether the hour finds the baptism or finds that the parish lost its books. ICAPGen says many professionals charge $50 to $200 an hour, as of October 2026, and that most ask for a retainer, a fee paid up front that the first hours are worked against. None of that is dishonest; an empty search still took the hours. But the risk that the records are gone sits with you, so the agreement should say what you receive when the hours end without an answer.

With me it works like this; the full rules are on the refunds page.

• At checkout your card is authorized, not charged. Within two business days you get the exact scope and total in writing. The payment is captured only when we've both said yes, you to the scope and total and I to the case. If either of us says no, the hold is released and nothing is charged.
• In the first week I check whether your lines can realistically reach the depth you bought. If one can't, you choose: switch to another line, or take a refund of what you've paid, minus the assessment fee if an assessment was done.
• On the 1700s and 1600s packages you pay in four equal parts: at the start, when a line reaches 1800, when it reaches 1700, and on delivery. If a line hits a true wall, billing stops at the last milestone reached, nothing further is due, and you keep everything found. Payments for milestones already reached aren't refunded. If you paid in full at checkout, the share for the milestones never reached comes back, minus the processing fee Stripe keeps.
• On the 1900 and 1800s packages there are two payments, the deposit and the balance on delivery, and what's delivered includes the trail for every line, including one that stopped.

On the $9,500 flagship, that's $2,375 to start and a second $2,375 when the research reaches 1800. If a line then hits a true wall before 1700, the two payments made are kept, the remaining two are never billed, and you keep everything found. Had you paid the full $9,500 at checkout, the $4,750 for the two milestones not reached would be refunded, minus the processing fee. You pay for the depth reached and for the proof of where it stopped, never for a milestone that wasn't.

Why is a guarantee a red flag?

Because there are only three ways to deliver one, and none is research.

The first is to copy. Online trees are full of unsourced parents, and anyone can attach them to your line and call it twelve generations. The second is to skip. If the record naming the father is missing, a guaranteed-results researcher picks the likeliest man of that surname in the county and moves on. The third is to search only the index, the typed list of names a website can find, and never open the unindexed pages behind it. All three produce a tree, not proof, and the error sits there until a cousin pays someone to find it.

ICAPGen's cost page says it directly: beware of any professional researcher claiming to solve your problem for a set number of generations for a set number of dollars. A thread on r/Genealogy asks whether anyone has hired a professional to break through a brick wall, and whether it worked. The answer to a bad guarantee is a written scope, a published price, and a bill that stops with the records. I walk through the vetting questions in How do I hire a genealogist without getting ripped off? and whether to hire at all in Is it worth hiring a professional genealogist?

And every package I deliver puts the record itself under the claim it proves, with the archive and the page number, so you never have to take my word for it. That is the only certainty this work offers.

If you'd rather have this done, start with the $300 Discovery assessment. It's a brick-wall check and a written research plan, credited in full toward any package. Start with the Discovery assessment.
