Reasons to Use a Process Server in the UK
July 4, 2021 - Reading time: 4 minutes
Updated on: August 7, 2025
When you need legal papers to be served on someone in the UK, employing a process server is crucial to ensure the documents are served correctly and legally.
What is a Process Server?
A professional UK process server is the individual who correctly delivers legal documents to a defendant or recipient. Different court orders and summons categories require specific service rules. UK-trained process servers know these and confirm the correct procedure before serving.
13 Reasons to Use a Process Server in the UK
Here are solid reasons to hire a UK process server to serve legal documents:
1. Ensure legal compliance and correct service
A professional UK process server ensures your service follows the Civil Procedure Rules and court requirements. Incorrect service can lead to case dismissal and wasted time.
2. Expertise in diverse document types
UK process servers understand service requirements for injunctions, statutory demands, divorce petitions, non-molestation orders and more.
3. Impartial and professional handling
Process servers are independent, objective professionals who prevent accusations of bias or improper motive.
4. Email or phone delivery is not valid
Contacting someone by email or phone does not constitute formal service and is not accepted by UK courts.
5. Safe handling of confrontational situations
Process servers are trained to manage hostility, unexpected reactions or difficult environments. They deliver documents calmly, safely and without escalating conflict.
6. Avoid personal confrontation
Handing documents yourself may be distressing or uncomfortable. A process server removes the emotional burden.
7. Some courts require independent serving
Courts often specify that documents must be served by a third party. A professional process server meets this requirement.
8. Expertise in tracing hard-to-find individuals
If the recipient is evasive or has gone off-grid, UK process servers often use professional tracing methods to locate them.
9. Skilled at serving in sensitive locations
Need to serve someone in prison? Process servers are familiar with protocols for serving documents within Her Majesty’s Prison Service.
10. Due diligence and legal professionalism
UK process servers follow correct legal procedures, maintain detailed records and deliver documents in a lawful and professional manner.
11. Legal proof of service provided
They supply a Statement of Service, Certificate of Service or Affidavit that is admissible in court as official proof the documents were served properly.
12. Efficient and traceable delivery
Many UK process servers use GPS tracking and digital tools to provide real-time updates and timestamped proof of delivery.
13. Timely service across the UK and internationally
Professional networks allow process servers to serve documents nationwide and abroad, following proper international protocols when required.
It Makes Sense to Hand Over to Professionals
Serving legal papers can seem straightforward at first, but the reality is that it often involves complex rules, evasive individuals and the need for valid proof of service. It’s usually more efficient and secure to hand the task to trained professionals.
When you hire a UK process server, they will ask for relevant details about the recipient, including any known addresses, contact history and circumstances. That helps them complete the service successfully and within the law.

How Police Detectives and Private Investigators are Different
July 3, 2021 - Reading time: 8 minutes
Updated on: August 7, 2025
Private investigators work for private individuals and companies (this is why we use the word “private” in the phrase “private investigators”), whereas police detectives work for law enforcement agencies which are funded by governments, effectively making them “public investigators”. This is the main difference between police detectives and private investigators, however, there are many other differences which we will explore deeper in this article.
1. Less red tape and paperwork
Private investigators are typically bound by less regulations and red tape than police detectives. Whereas the police will typically need abide by a myriad of ever-changing regulations, ethical standards policies, risk assessments, along with various other forms of bureaucratic form filling and box ticking; private investigators typically have less formalities to deal with, even in jurisdictions where a regulatory body licenses private investigators.
Of course, many detectives that work in law enforcement eventually decide to pursue careers within the private investigation industry instead; and many of our colleagues that have taken this leap will comment on their relief to avoid paperwork and box ticking which forms a big part of modern policing in the UK.
2. More discretion
Police detectives are in many cases bound by the decisions of other people; whether that be a senior investigating officer or a prosecution lawyer deciding not to pursue a case. Private investigators have more freedom to act on instructions that are provided by their clients, without interference from other people or bodies.
3. More flexible working hours
As private investigators, we often take on cases which are limited to an allocated time. However, if the case takes an unforeseen turn, then our client may ask us to work overtime. Depending on the case, we can work from the evening until the early hours of the morning, or purely during normal business hours.
Working within a detective agency provides a certain amount of freedom to delegate work to specific agents as needed. Whereas police detectives may need to work a certain amount of hours in order to be eligible for their salaries, private investigators have a lot more freedom to arrange their working hours and concentrate time on cases as needed.
4. More freedom over gadgets and equipment
While we don’t mean to suggest that police detectives are underequipped (this is definitely not the case), private investigators can sometimes have more freedom over the type of equipment and gadgets which they can use, depending on the agency.
For example, if one of our private investigators feels that it would benefit the case, (s)he might decide to spontaneously pull out a drone in order to discreetly monitor a subject. While police detectives certainly can use technology such as drones, they might seldom be able to decide that doing so could benefit the case at a moment’s notice, and use one without seeking permission from higherups.
Private investigators often spend a substantial amount of time (and money!) choosing their camera gear, lenses, discreet cameras, and any other equipment which might benefit a case. We can effectively use whichever gear we decide is appropriate, without seeking approval or funding.
5. Detectives investigate crime
This may seem like an obvious point though it should be mentioned… Police detectives are usually tasked with investigating crimes, of varying severities and associated risks. Private investigators, on the other hand, can investigate anything from infidelity, to accident injury claims, fraud, and a long list of other cases.
Private investigators typically will not delve into criminal investigations, though this can depend on the jurisdiction – investigators in north America more commonly accept criminal cases, whereas in the UK this is less common. Whether a private investigator is looking into a criminal matter or a personal dilemma, all investigations are completed with the same level of skill, dedication, and attention to detail.
6. Police detectives can access confidential data
One of the major advantages held by police detectives is their ability to access confidential data and information which is off-limits to normal members of the public. Law enforcement agencies around the world have access to vast amounts of records and intelligence data which can be used whilst conducting investigations.
While private investigators do not have access to the same information as police detectives, they are able to utilize public records, and information from third parties such as social media providers, to help locate people or assist during investigations.
7. Detectives can carry self-defence equipment
Police detectives around the world will often carry firearms as part of their ordinary work. In the UK of course, detectives may not ordinarily carry firearms but may instead have access to PAVA spray or Tasers.
By contrast, private investigators working in the UK have absolutely no rights to carry firearms, or any object which could be used for the purpose of self-defence. In the UK at least, private investigators have no special rights to carry firearms or any weapons at all… And rightfully so. A competent investigator will not make themselves known to the subject or anyone else. When conducted properly, the risks involved with private investigation should be kept to an absolute minimum and there should be no need for an agent to possess self-defence equipment.
8. Different investigative techniques
Police detectives are often bound by conventional investigative techniques which must be used in order to ensure that evidence is admissible and meets the relevant thresholds for prosecution. The evidence must stand up to scrutiny and have been gathered within the relevant police guidelines.
Private investigators on the other hand have more freedom to gather evidence using unconventional methods. Whilst private investigators are not allowed to break the law, they are free to use more imaginative tactics which might be described as immoral by some.
Of course, the techniques used during any given investigation will largely depend on the intended use for our evidence in each case. If we are gathering evidence for use in civil courts, for example, then care should be taken to ensure that all evidence gathered is admissible.
9. More resources and funding
We often read about police budget cuts and funding issues. However, when the police decide that a matter is truly worthy of their attention, they will typically receive adequate funding in order to conduct a full and thorough investigation to the best of their abilities.
When police are tasked with conducting surveillance, for example, they may use several agents, or even a dozen or more people working on the case at any given time.
During private investigations however, we are often confined by our client’s budgets. Surveillance assignments are often conducted by just one investigator at a time, which is often adequate, though adding agents will almost always benefit a surveillance case.
Other times clients may decide to stop an investigation at a time when the investigator believes they are close to making a breakthrough.
Whatever the case, having a higher budget for an investigation will ensure better results in virtually every scenario. As private investigators we must cater to our clients’ budgets in each case.
Choosing a career in private investigation
Many of the investigators that work for our agency come from a previous background in law enforcement. Police detectives are traditionally held in the highest esteem within our industry, and we are always eager to work with more former law enforcement detectives.

How Private Investigators Help Solicitors in the UK
June 28, 2021 - Reading time: 7 minutes
Updated on: August 7, 2025
Private investigators can be hired by members of the public under many different circumstances, from investigating cheating partners to catching fly-tippers. However, private investigators also work closely with law firms and often receive instructions directly from solicitors on a wide range of legal matters.
Such is the value of private investigators to the legal sector that some solicitors in the UK rely on PIs in nearly every case they handle [source]. Below are some of the key services provided by private investigators that assist solicitors in civil, family, and criminal law cases.
1. Injury claim investigations
Personal injury investigations are one of the most common reasons solicitors hire private investigators. If someone is claiming to be unable to walk unaided, yet is seen playing football by a PI, that evidence can significantly weaken their case. In many situations, the claimant may drop their case entirely once confronted with surveillance footage or photographic evidence.
This type of evidence gathering helps law firms save time and money by avoiding lengthy and unnecessary litigation.
2. Process serving (legal document delivery)
Solicitors regularly need legal documents served on individuals or businesses. Hiring a private investigator as a process server ensures that documents are delivered properly, within legal guidelines, and with proof of service.
Common documents served by PIs in the UK include:
- Winding-up petitions
- Divorce petitions
- Bankruptcy papers
- Statutory demands
- Prohibition orders
- License applications
This service is especially useful when recipients are evasive or difficult to locate.
3. Support with divorce and family law cases
In divorce cases involving infidelity, hidden assets or child custody disputes, private investigators help gather evidence to support a solicitor’s case. The average divorce in the UK costs over £14,000 in legal and lifestyle costs, and the stakes can be far higher when property or business interests are involved.
Clear evidence of cheating or financial misconduct can be critical in achieving a fair settlement.
4. Tracing people and debtors
Private investigators are skilled in locating missing persons, evasive debtors, or former clients who have disappeared. Solicitors may need to trace individuals before initiating proceedings, serving documents, or enforcing court judgments.
Using public record searches, surveillance, social engineering, and proprietary databases, PIs can often locate subjects who are actively avoiding contact.
5. Interviewing witnesses or gathering statements
Interviewing witnesses or character references is another area where solicitors benefit from hiring a private investigator. In cases involving personal injury, fraud, or workplace incidents, PIs can collect statements or evidence that supports the solicitor’s legal strategy.
Hiring a PI can also reduce costs, as their fees are typically lower than those of qualified legal professionals.
6. Lie detector testing (polygraph services)
Polygraph testing is sometimes used to resolve disputes, clarify allegations, or support legal strategies in family or civil cases. Although lie detector results are not typically admissible in court, they can be used by solicitors as supporting material or to guide negotiations.
Private investigators who are trained in polygraph testing may conduct these exams in private residences or solicitor’s offices.
7. Locating hidden assets
Solicitors often instruct PIs to help trace assets that a person may be trying to conceal. This is particularly useful in divorce settlements, debt recovery cases, or business disputes where one party may be attempting to hide income, property, or other financial holdings.
Asset tracing helps ensure a fair and transparent outcome in legal proceedings.
8. Intellectual property investigations
Private investigators support solicitors in identifying and proving cases of intellectual property theft. This could involve tracking down counterfeit goods, identifying rogue suppliers, or collecting evidence of unauthorised brand use.
Evidence gathered by PIs can help build strong IP cases for court or settlement negotiations.
9. Social media and online investigations
Private investigators are frequently hired to conduct deep dives into a subject’s online presence. Social media platforms, forums, and other digital footprints can reveal useful information about behaviour, character, lifestyle, and associations.
Such evidence can support civil claims, background checks, family law matters, and more.
10. Background checks for due diligence
Whether a solicitor is working on a merger, hiring case, or business partnership vetting, private investigators can help conduct thorough background checks on individuals or companies. This ensures no surprises arise down the line and helps mitigate reputational or financial risk.
Due diligence investigations are especially valuable before signing contracts or entering legal agreements.

Top Reasons for Hiring a Private Investigator
Cheap Private Investigators and Why to Avoid Them
Top Reasons to Hire a Private Investigator in the UK
June 22, 2021 - Reading time: 5 minutes
Updated on: August 7, 2025
People often assume private investigators are only hired in extreme situations, but the truth is quite the opposite. In the UK, private investigators assist with a wide range of sensitive, personal, and legal matters - many of which the police either can't or won't handle.
If you need verified information, surveillance, or help finding someone, hiring a private investigator could be the most efficient way to get answers. Below are 12 of the most common reasons people in the UK choose to hire a PI.
1. Infidelity investigations
Suspect your partner might be cheating? Living in doubt can take a toll on your wellbeing. Private investigators can discreetly monitor your partner’s activities, providing photo or video evidence. This evidence can help bring clarity - and closure - whether you're seeking peace of mind or preparing for legal proceedings.
2. Background checks before marriage or dating
Whether you’ve met someone online or are planning to marry a foreign partner, it’s wise to verify their background. A PI can confirm identity, marital status, employment, education, and more. Better safe than sorry - especially when legal issues or immigration processes are involved.
3. Child custody disputes
If you're going through a custody battle, proving your child’s welfare is key. Private investigators can gather evidence of neglect, risky behaviour, or dishonesty - helping your solicitor build a stronger case. Surveillance and witness interviews can be presented in court if needed.
4. Tracing missing people or debtors
Need to find someone? Whether it’s a missing relative or someone who owes you money, private investigators can help. We use public records, databases, and investigative techniques to locate missing persons or trace debtors across the UK.
5. Insurance or benefit fraud investigations
Insurance and welfare fraud cost businesses and taxpayers millions every year. Private investigators are often hired by insurers or councils to verify claims. We’ve exposed cases where claimants with “life-limiting injuries” were seen playing sports or doing manual work.
6. Identity theft or online scams
Victim of fraud or identity theft? A private investigator can help you collect evidence, identify the source, and even assist the police with a stronger case. We can also help prevent future attacks by identifying data breaches or points of exposure.
7. Business and employment background checks
If you're hiring a senior employee, onboarding a business partner, or making a major investment, conducting due diligence is critical. Private investigators can vet companies or individuals to uncover red flags like previous bankruptcies, litigation, or false qualifications.
8. Pre-investment checks (UK and overseas)
Thinking about investing in a startup or an international company? A private investigator can help confirm whether the opportunity is legitimate. We investigate business registration, legal history, key personnel, and financial credibility - especially important for overseas ventures.
9. Investigating stalking or harassment
If you're being followed, threatened, or harassed, it may not meet the police threshold - but that doesn't mean you're on your own. A PI can help identify the stalker, gather evidence, and support your efforts to get a restraining order or take legal action.
10. Social media investigations
More and more legal disputes involve information found on social media. We can document online behaviour, flag suspicious profiles, or uncover fake identities used to deceive or harass. This is particularly useful in family law and fraud cases.
11. Verifying personal relationships or online identities
If you suspect catfishing or are concerned about someone you met online, a PI can check whether their profile is real. We verify identities, photos, addresses, and personal claims so you can move forward with clarity - or step back if something’s off.
12. Corporate fraud or intellectual property theft
If your business is losing money or you suspect internal fraud, hiring a private investigator can help. We work discreetly to uncover theft, data leaks, or unauthorised use of company property. We also investigate trademark infringement and counterfeit goods.
