"You were recommended to us in the first place by the United States Embassy and we are grateful to them for their introduction to you and would not hesitate to use your services again or to recommend you."

D. H. P. Levy & Co., London

“You are finding heirs that we might never find and you are doing it faster and with greater economy than me spending our limited and valuable staff time."

John J. Cahill, Clark County

"I want to thank you and all for "tracking" me down in this remote location, and for your expeditious handling of my inheritance."

Respectfully, Bill Massengill

"I had hired an investigator to ascertain the dates of death and whereabouts of next of kin to Ruth Evans. After two months of diligent searching, he found nothing concrete… Within two days following our first conversation, I received a call indicating the possibility of success. It was indeed my long lost relative. I only wish I had found and used you sooner."

Von Langen, LLC specializes in missing heir search services. When you need to find a missing heir at law or you are concerned with locating missing beneficiaries our dedicated team of forensic genealogists and estate investigators conducts extensive missing heir searches to find missing heirs at law or find unknown heirs and locate missing beneficiaries across the United States and around the globe.

We offer you our long list of prominent clients who will attest to our expertise in forensic genealogy and our commitment to exceptional service, performing exhaustive heir research to identify unknown heirs, and locate missing heirs anywhere in the world. Our excellent reputation and long history of successful cases serve as proof of our unparalleled track record for locating missing heirs for a proper determination of heirship, notice to unknown heirs and unknown devisees, notice to missing heirs and search for missing devisees, action to quiet title to real property or quiet title suit (cloud on title), unknown heirs entitled to oil, gas, and mineral rights, and heir tracing for unclaimed estates or probate research, missing intestate heirs or unknown intestate heirs for the fiduciary responsible for inheritance distribution and to find missing beneficiaries or missing trust beneficiary location to account for every missing remainderman.

Von Langen’s findings prove heirship, or refute suspect claims put forth by an alleged heir or heir hunter (in many cases alleged heirs appear due to heir hunters).  We possess extensive experience not only as heir finders or heir tracers, but also in preparation of forensic genealogical researcher affidavits as proof of heirship and for compliance with due diligence requirements, including compilation of documentary evidence as court admissible exhibits. You can trust our missing heir location services as we not only locate heirs, we provide you with verified heirship documentation. As an added assurance, we offer you a one-million dollar professional liability insurance policy against errors and omissions — though we have never had a claim.

For even the most complex international genealogical search for heirs, you can rely on Von Langen’s heir locators and heirship researchers whose accuracy and professionalism comes with our wealth of experience finding heirs. As heir searchers, we offer you reasonable fees for heirs located or missing trust beneficiaries located with payment options to best suit your budget and preference. In many cases where we must find heirs, the most economical cost-basis for our heir finder services and proven heirship is an hourly rate for locating heirs; however, you may prefer an alternative fee arrangement for your lost heir case or search for beneficiaries. In every missing beneficiary search or unknown heir case, our heir finding services and missing beneficiaries searches are backed by the best lost heirs guarantee you could receive from any other heir search firms or heir search companies: Our fee is earned only after our clients’ requirements have been satisfied.

    Webster B. Baker Attorney at Law
  • As we discussed, six years ago,

    you did a fine job for me in a case about which I’ve spoken in classrooms to paralegals, and to lawyers at seminars. The family tree you provided covered 3 out of 4 of the courtroom’s walls. An amazing case. Not sure this assignment will rise to the level of that one, but nevertheless I am sure you are up to the task. I have been appointed by the Court as the Attorney ad Litem to find the missing heirs. Thank you very, very much for your willingness to help us in this case.
