Estate and Trust

We use our professional expertise to identify, locate, prove and report known and unknown heirs or beneficiaries, both domestically and internationally.


We help clients fulfill their fiduciary responsibilities in providing notice to heirs by supplying current contact information (or the results of our due diligence search efforts) in order to provide notice of estate or trust matters.


We identify, locate, prove and report heirs or beneficiaries on matters related to Clear and Quiet Title Actions and Property Ownership.
