Legal & Fiduciary Research
Evidentiary clarity for probate, trust, and estate professionals.
The Challenge: Probate matters and estate administrations often encounter critical blockages when heirs are missing, kinship is undocumented across jurisdictions, or evidence is insufficient to meet judicial standards of "due diligence."
Our Capabilities: ALERCE specializes in resolving these complexities, particularly in cases involving the Rio de la Plata region and international archival gaps.
Heir Identification & Location: Specialized search for missing or unknown heirs across multi-regional legal frameworks.
Kinship Documentation: Building defensible evidentiary chains to support legal claims and distribution of assets.
Diligent Search Support: Diligent Search Support: Conducting and documenting search efforts requested by counsel, fiduciaries, courts, or appointing authorities.
Cross-Border Coordination: Navigating international archives and integrating civil, ecclesiastical, and genetic evidence into a single analytical framework.
DeliverablesWe deliver decision-oriented research reports, documented search summaries, and evidentiary dossiers prepared for review by counsel, fiduciaries, or relevant authorities. Our conclusions clearly distinguish verified findings, unresolved gaps, and recommended next steps.
Historical & Cultural Heritage Research
Expert historical, biographical, and provenance investigations.
Institutions, archives, and private collectors often require reliable, well-documented evidence to establish the origin, ownership history, or historical context of people, collections, and cultural assets.
These investigations frequently involve cross-jurisdictional records and complex archival navigation
Our Capabilities: ALERCE integrates multidisciplinary historical research with analytical rigor to provide:
Provenance Research: Reconstructing the ownership, custody, and documentary history of cultural assets and historical materials.
Biographical Verification: Reconstructing detailed lives and trajectories through primary source integration.
Archival Navigation: Accessing and interpreting records across international repositories, with specialized expertise in the Río de la Plata region.
Historical Contextualization: Synthesizing disparate evidence to provide a well-supported interpretation of events, people, or identities.
Deliverables
We provide comprehensive historical reports and fully sourced research dossiers designed to support exhibitions, publications, collection management, and institutional record-keeping.
Genealogical, Genetic & Identity Research
Rigorous integration of documentary and genetic evidence for complex identity queries.
Complex questions of biological identity, lineage, and parentage require a structured genetic-genealogy investigation—not merely the review of existing DNA matches. At ALERCE, the work begins with the analysis of available genetic evidence and the development of testable kinship hypotheses. We then design and implement a targeted DNA-testing strategy, identifying the relatives whose results can distinguish among competing hypotheses, obtaining their informed consent and participation, coordinating successive tests, and evaluating each result within the reconstructed family network. Genetic findings are correlated with civil, ecclesiastical, archival, and historical records to produce a thoroughly documented and well-supported conclusion.
Our Capabilities: ALERCE applies its Investigative Framework to resolve questions where standard research is insufficient:
Biological Identity & Kinship: Resolving questions of unknown parentage and biological relationships through genetic-network analysis, targeted DNA-testing strategies, and systematic hypothesis evaluation.
Complex Lineage Reconstruction: Reconstructing and verifying multi-generational relationships across international jurisdictions, fragmented record systems, and historical periods.
Strategic DNA Testing: Identifying the relatives whose participation can provide the most probative evidence, facilitating their informed and voluntary participation, coordinating successive tests, and evaluating each result within the reconstructed family network.
Integration of Genetic & Documentary Evidence: Correlating DNA results with civil, ecclesiastical, archival, and historical records to test, refine, and substantiate kinship conclusions.
Deliverables
We deliver comprehensive analytical reports that synthesize genetic and documentary findings into clear, thoroughly documented, and well-supported conclusions.
Selected Engagements
The following anonymized engagements illustrate ALERCE’s approach to complex, cross-jurisdictional research and evidentiary analysis. Details are limited to protect client confidentiality.
CASE I
International Provenance Investigation for a Cultural InstitutionContext: Independent research support for an institutional provenance project involving biographical, genealogical, and historical documentation connected to the Río de la Plata region.Complexity: The investigation required reconstructing evidentiary links across fragmented archival systems and multiple international jurisdictions where surviving documentation was incomplete.The Approach: ALERCE combined localized archival research with biographical and genealogical analysis. Evidence from different repositories and record systems was evaluated, reconciled, and organized into a documented chronology that clearly distinguished verified findings, unresolved gaps, and analytical conclusions.Outcome: Delivered a fully sourced research dossier that addressed significant biographical, geographical, and archival gaps and provided the institution with a well-supported evidentiary basis for its provenance assessment.
CASE II
Biological Identity Resolution through Genealogical Research and Strategic DNA Testing
Context: A private matter requiring the identification of biological parentage in a case in which no reliable documentary or testimonial leads were available.Complexity: The investigation faced significant challenges due to unknown paternity and dispersed genetic data across multiple, distant DNA matches without a clear genealogical anchor.The Approach: ALERCE developed a targeted DNA-testing strategy to distinguish among competing kinship hypotheses. This required identifying the relatives whose results would provide the most probative comparisons, facilitating their informed and voluntary participation, and coordinating a sequence of additional DNA tests. Each new result was evaluated within the reconstructed family network and in conjunction with documentary evidence, allowing the hypothesis to be progressively tested and substantiated.Outcome: Within the first week of analysis, ALERCE developed the hypothesis that ultimately proved correct regarding the identity of the biological father. Over the following four months, a series of strategically selected DNA tests provided the evidence required to substantiate that hypothesis and establish a well-supported conclusion.
