Law Firm Support Services
SIP has offered comprehensive support services to legal firms since 1983, covering a wide range of activities from basic person tracing to complex global investigations into fraud, product piracy, asset tracing, and gathering evidence to support criminal defence, alongside domestic and commercial surveillance, technical surveillance countermeasures, digital forensics, and other related intelligence and security activities necessary for their clients.
Our open-source intelligence gathers data and documents from the surface, deep, and dark webs. We have access to hundreds of global subscriber and public databases worldwide and deploy on-the-ground human resources in most jurisdictions. Our reports are fully digitised for easy reference and comply with UK and European GDPR Data Protection laws. We understand the complexities of cross-jurisdictional legislation and provide assistance to help avoid potential legal pitfalls and enforcement issues.
Every investigation is unique; therefore, we carefully review the files presented to us to ensure that all investigative avenues are explored and that a positive outcome is achieved for the client. We therefore welcome the opportunity to discuss your requirements and provide you with a personalised proposal.
Law Firm Support Services We Provide
SIP delivers specialised global investigation services designed to support corporate organisations, legal professionals, and private clients worldwide. With decades of international experience, advanced intelligence tools, and discreet investigative strategies, our teams provide accurate insights, asset recovery solutions, and strategic protection across complex cross-border matters.
Asset Trace – Settlements & Debt Recovery
SIP has specialised in tracing tangible and liquid assets since 1983 and has successfully tracked multi-millions in GBP, USD, Euros, other foreign currencies, and cryptocurrency exchanges globally.
Our intelligence and analyst team specialists possess multidisciplinary investigative skills essential for effectively locating and identifying assets involved in high-level fraud, corporate embezzlement, divorce settlements, bankruptcy, and sanctions evasion. These assets are often concealed through complex financial structures such as shell companies, offshore accounts, trusts, cryptocurrencies, and nominee arrangements designed to obscure the true ultimate beneficial owner.
Asset tracing works alongside legal teams to provide “courtroom-ready” evidence for civil litigation, insolvency proceedings, or criminal prosecutions, often initiating emergency measures like injunctions to prevent further asset dissipation.
At SIP, we excel at establishing asset ownership and providing “courtroom-ready” reports that demonstrate links to evidence for civil litigation, insolvency proceedings, or criminal prosecutions. Our reports support applications for disclosures, freezing injunctions, and other legal measures to prevent further asset dissipation and facilitate asset recovery. With SIP’s extensive knowledge of cross-jurisdictional laws and procedures, we often assist legal teams in navigating potential pitfalls to ensure clients achieve a satisfactory outcome in securing the financial award to which they are entitled.
Therefore, if you need to trace assets for any legal purposes, contact SIP to discuss your case.
M&A and Potential Partner Due Diligence
Over the decades, the approach to M&A investigative due diligence has significantly evolved due to rising risks in many jurisdictions, stricter global sanctions, and the possible involvement of directors, shareholders, and key executives in money laundering, corruption, or other criminal activities.
Now, in 2026, SIP provides a multi-layered process that investigates a target company’s overall business activities, reputation, and financial and commercial stability by verifying valuations, uncovering hidden liabilities, identifying historical and ongoing litigation matters, and more. This also involves the company’s directors, shareholders, and key executives, who are critical to daily operations, aiming to determine any ultimate beneficial ownership they may hold in other entities, recognise links to anti-money laundering, sanctions, politically exposed persons, organised crime, criminal and civil proceedings, and evaluate their business and social conduct, along with relationships with competitors and other relevant factors for the client’s awareness.
SIP reports are fully digitised, featuring a comprehensive executive summary, schematic corporate structures,and other relevant links where applicable. All facts are verified by a team of expert analysts to ensure you receive a report that supports informed strategic risk assessments.
The same principle applies when evaluating a potential business or personal partner, whether for yourself or a client, as thorough due diligence is essential for understanding more about the individual you will be engaging with. This helps to reduce the risk of scams or inadvertently becoming involved in criminal activity. SIP reports provide a comprehensive overview of their background and current status, enabling you to make a well informed decision about potential risks. If you decide there isn’t a risk, it will offer some reassurance of a stable business or personal relationship.
If you require extremely comprehensive due diligence, whether for M&A or a business or personal partner, reach out to us today for a confidential consultation.
Commercial Litigation Investigation
SIP has been providing law firms worldwide with detailed investigation and intelligence reports for decades, supporting complex, high-stakes legal disputes involving business entities or individuals where wrongdoing is suspected. At SIP, we establish the truths behind disputed claims, such as testing the accuracy of sworn statements and disclosures, identifying hidden income streams, beneficial ownership, and assets concealed through complex corporate structures or nominees, confirming identities, residences, and jurisdictional facts, and investigating cases of fraud, misappropriation, corruption, and other white-collar crimes.
Alongside our expertise in gathering the necessary intelligence to support the client’s claim, we collaborate with your legal team to identify specific evidence gaps, such as incomplete or distorted facts. We also review the opposition’s witness statements and expert reports to assess whether there are grounds to challenge them, or if the client’s evidence can withstand cross-examination. We supervise the collection and conduct forensic analysis of relevant documents and electronic data under the client’s control for e-discovery. Furthermore, when we locate assets globally, we assist in evaluating whether a judgment, if obtained, would be enforceable within the relevant jurisdiction.
If you need an investigation for commercial litigation, don’t rely solely on an existing provider who might not have the same capabilities; contact us for a free consultation and a proposal to compare coverage, so you can maximise your chances of winning your client’s case.
Matrimonial & Family Investigations
Since our incorporation in 1983, SIP has represented numerous small and large law firms in uncovering facts,verifying backgrounds, and gathering evidence for personal, legal, and family matters, including divorce and child custody issues.
These cases involve individuals from diverse backgrounds and may relate to tracing assets for financial settlements, gathering evidence of infidelity or suspected substance abuse, domestic violence history, or gambling habits that could endanger family members. They also include investigations into threats of blackmail and extortion, stalking, tracing beneficiaries, and these are just some of the many reasons why lawyers have instructed SIP.
Regardless of the case type, SIP possesses the expertise, global intelligence capabilities, on-the-ground investigators, and physical surveillance teams in most jurisdictions to handle any matrimonial or domestic family matter.
SIP has an established record of success, so if you require a dependable professional report prepared in line with local privacy and data protection laws to ensure its admissibility in court, contact us to discuss your case and receive our proposal.
Criminal Defence & Private Prosecution
SIP has supported many defence lawyers over many years, whose cases have included the defence of those accused of illegal importation of drugs, murder, theft of industrial secrets, corruption, extortion, robbery and many other crimes, which in some instances have contributed to achieving a not guilty verdict.
At SIP, we have extensive experience analysing case materials, conducting independent examinations of crime scenes, taking photographs, and creating diagrams to better understand the scene beyond what may have been depicted by the prosecution. Additionally, we cover all other essential aspects of investigation, which may include, but are not limited to, locating additional witnesses, taking witness statements, conducting background checks on witnesses for both the prosecution and defence to assess the reliability of their evidence, and, where applicable, undertaking time-runs between multiple locations, analysing mobile cell tower data for location verification, and performing digital forensics on devices seized by the prosecution as well as other persons’ devices that may contain evidence supporting the defendant’s innocence.
In recent years, there has been an increase in private criminal prosecutions, particularly by lawyers representing corporate entities, as this offers greater control, allowing for swifter action in complex fraud cases, and serves as a deterrent against misconduct, especially in the corporate or financial sectors. SIP has the experience and extensive capabilities to gather the necessary supporting evidence to help achieve a successful conviction, as well as identifying financial assets that may have been obtained from the proceeds of crime.
SIP is here to support legal teams in these investigations and would welcome the opportunity to prepare a proposal based on the information you provide us so that you can see how detailed our scope of work will be to establish the facts on your behalf.
