Summary
The decision in Goh Yong Hng v Cheong Yen Teng (Zheng Yanping) (m.w.) and Another [2003] SGHC 89 serves as a definitive High Court authority on the quantification and recoverability of private investigation costs in matrimonial proceedings predicated on adultery. The appeal, heard before Judith Prakash J, centered on the husband’s challenge to a District Court order which had significantly curtailed the reimbursement of expenses incurred in hiring private investigators to prove the wife’s infidelity with the co-respondent. While the lower court had awarded only 25% of the total investigative fees, the High Court was tasked with reconciling the "but-for" causation of the co-respondent’s conduct with the statutory requirement of "reasonableness" in the taxation of costs.
The dispute originated from a divorce petition filed by the husband on 1 July 2002, following a period of surveillance that confirmed an act of adultery on 9 May 2002 at a flat in Bishan. The husband had incurred a total of $8,780 in fees from the firm of Mr. Philip Tan. The District Judge, applying Order 59 Rule 27(2) of the Rules of Court, found the fees to be excessive and the co-respondent’s liability to be limited, ultimately ordering the co-respondent to pay only $2,195. This figure was derived by first halving the total bill to determine a "reasonable" amount and then halving that figure again to reflect the co-respondent’s perceived share of responsibility alongside the wife.
On appeal, the High Court engaged in a meticulous deconstruction of the investigative bill and the principles of apportionment. Justice Prakash clarified the doctrinal distinction between the co-respondent’s liability for the breakdown of the marriage and their liability for the costs of the litigation. The judgment refined the application of the "reasonableness" test, distinguishing between investigative work necessary for the legal "fact" of adultery and work performed for the petitioner’s personal satisfaction or "peace of mind."
The final determination by the High Court varied the lower court’s order, increasing the co-respondent’s liability to $3,890. This result underscored a significant shift in the judicial approach to matrimonial costs: while the court will not grant a "blank cheque" for private surveillance, it will ensure that a co-respondent whose actions necessitate litigation bears a substantial and fair portion of the reasonable costs incurred to prove those actions. The case remains a critical touchstone for practitioners in assessing the financial risks for co-respondents and the evidentiary requirements for petitioners in adultery-based divorces.

What Were the Facts of This Case?
The marriage between the husband (Goh Yong Hng) and the wife (Cheong Yen Teng) reached a terminal point in mid-2002. The husband’s petition for divorce was founded upon the irretrievable breakdown of the marriage due to the wife's adultery with the co-respondent (Goh Yik Liang). The parties had first become acquainted in January 2002. According to the husband, the marriage was stable and the wife appeared happy until the intervention of the co-respondent. Conversely, the co-respondent alleged that the wife had expressed significant unhappiness in the marriage and that the relationship had effectively broken down before the adulterous affair commenced.
On 8 May 2002, the husband engaged the services of a private investigation firm led by Mr. Philip Tan. The primary objective was to obtain concrete evidence of the suspected affair. The investigation was swift; on the very next day, 9 May 2002, investigators tracked the wife and the co-respondent to a flat in Bishan, where the act of adultery was documented. Despite having obtained this evidence, the investigators continued their surveillance on 10 May and 13 May 2002. The husband maintained that this extended surveillance was necessary to ensure the evidence was robust enough to withstand a potential legal challenge.
A pivotal moment occurred on 15 May 2002. A meeting was arranged involving the husband, the wife, and the co-respondent. Crucially, the husband requested the presence of Mr. Philip Tan at this meeting. During this confrontation, the co-respondent made an offer to settle the private investigator's fees, an act the husband later characterized in his petition as an implied admission of adultery. The total bill presented by the private investigators amounted to $8,780. This sum was comprised of $7,170 for three days of surveillance, $1,010 for the preparation of the formal report and affidavits, and $600 for the investigator's attendance at the 15 May meeting.
The husband filed his divorce petition on 1 July 2002, citing two main particulars of adultery: the incident in the Bishan flat on 9 May and the implied admission on 15 May. When the matter came for hearing on 24 September 2002, the wife and co-respondent chose not to contest the allegations. Consequently, the court granted the divorce. However, the financial aftermath—specifically the husband's claim for the full reimbursement of the $8,780 investigation costs from the co-respondent—became the subject of intense litigation.
In the initial proceedings before the District Judge, the husband argued that the co-respondent was the primary cause of the litigation and the marriage's end, and thus should bear the full weight of the investigative costs. The co-respondent resisted this, arguing that the fees were exorbitant and that the marriage was already failing. The District Judge took a restrictive view, determining that since the evidence was obtained on the first day, the subsequent surveillance was redundant. The District Judge also found that the wife, as a willing participant in the adultery, shared the blame. This led to the initial order where the co-respondent was only required to pay 25% of the total bill, amounting to $2,195. The husband, dissatisfied with this recovery, appealed to the High Court, seeking the full $8,780.
What Were the Key Legal Issues?
The appeal raised three primary legal issues concerning the intersection of family law and the law of costs:
- The Principle of Liability for Investigation Costs: Whether a co-respondent, having been found to have committed adultery, is prima facie liable for the costs of private investigators hired by the petitioner to prove that adultery. This involved an analysis of whether the "but-for" test of causation applies to such expenses.
- The Test of Reasonableness under Order 59 Rule 27(2): How the court should determine if investigative fees are "reasonably incurred" and "reasonable in amount." This required the court to scrutinize the necessity of surveillance conducted after the initial evidence of adultery was obtained and the necessity of an investigator's presence at non-legal meetings.
- The Apportionment of Costs: Whether the co-respondent should be held liable for the entirety of the reasonable costs, or whether those costs should be apportioned between the co-respondent and the wife (or the petitioner) based on their respective roles in the breakdown of the marriage and the necessity of the litigation.
These issues are significant because they define the boundaries of financial indemnity for a wronged spouse. If the threshold for "reasonableness" is set too high, petitioners may be deterred from gathering necessary evidence; if set too low, co-respondents may be unfairly burdened with the costs of a petitioner's excessive or retaliatory investigative measures.
How Did the Court Analyse the Issues?
Justice Judith Prakash began her analysis by addressing the foundational principle of a co-respondent's liability for costs. She noted that the law relevant to the application was encapsulated in Halsbury’s Laws of England (4th Ed) at paragraph 970, which states:
"A co-respondent, against whom adultery is established, may be ordered to pay the whole or any part of the costs of the proceedings, but in exercising its discretion as to the costs which a co-respondent may be ordered to pay, the court may have to consider whether in fact the co-respondent was responsible either for the breakdown of the marriage or for the litigation." (at [8])
The court first dealt with the "but-for" argument. Justice Prakash agreed with the District Judge that the husband would not have been put to the expense of engaging a private investigator but for the co-respondent’s act of adultery. At paragraph [7], the court observed that the co-respondent’s conduct necessitated the gathering of evidence to support the petition. However, the court distinguished the case of Tan Kay Poh v Tan Surida & Anor [1988] SLR 983. In that case, the court had refused to award costs against a co-respondent because the marriage had already completely broken down before the adultery occurred. In the present case, while the marriage may have been "shaky," Justice Prakash found that it had not reached the point of total breakdown until the adultery was discovered. Thus, the co-respondent bore responsibility for the litigation.
The analysis then shifted to the "reasonableness" of the $8,780 quantum. The court applied Order 59 Rule 27(2) of the Rules of Court, which mandates that "there shall be allowed a reasonable amount in respect of all costs reasonably incurred." Justice Prakash scrutinized the breakdown of the $8,780 bill:
- $7,170 for surveillance on 9, 10, and 13 May 2002.
- $1,010 for the report and affidavits.
- $600 for the meeting on 15 May 2002.
The District Judge had previously held that only the first day of surveillance (9 May) was necessary, as the evidence obtained then was sufficient. Justice Prakash disagreed with this overly restrictive view. She reasoned that a petitioner is entitled to ensure that the evidence is not a "one-off" occurrence and that the case is "watertight" before filing a petition. She noted at paragraph [15] that it is "prudent for a petitioner to have more than one instance of adultery to rely on." Consequently, she found that the surveillance on 10 and 13 May was reasonably incurred. The total surveillance fee of $7,170 was therefore deemed reasonable.
However, the court took a different view regarding the $600 charge for the investigator's attendance at the 15 May meeting. Justice Prakash held that this meeting was not for the purpose of gathering evidence for the litigation, but rather for the husband's "own purposes" and "peace of mind" (at [17]). The co-respondent should not be expected to subsidize the husband's desire for a confrontation in the presence of his investigator. Furthermore, the court found the $1,010 charge for the report to be slightly excessive, reducing the reasonable portion of that specific item to $610. Thus, the total "reasonable" cost was determined to be $7,780 ($7,170 + $610).
The final stage of the analysis concerned apportionment. The District Judge had reduced the co-respondent's liability to 50% of the "reasonable" amount because the wife was a willing participant. Justice Prakash upheld this 50% apportionment principle. She reasoned that while the co-respondent was responsible for the litigation, the wife was equally responsible for the act of adultery itself. Since the husband could not (or chose not to) recover costs from the wife in this specific context, the co-respondent should only bear his half-share of the responsibility. Applying 50% to the revised reasonable sum of $7,780, the court arrived at the figure of $3,890.
What Was the Outcome?
The High Court allowed the appeal in part. Justice Judith Prakash varied the order of the District Judge regarding the investigation costs. The co-respondent was ordered to pay the husband $3,890, an increase from the $2,195 ordered by the lower court. The court maintained the 50% apportionment ratio but applied it to a much higher base of "reasonable" costs ($7,780 instead of $4,390).
The operative paragraph of the judgment stated:
"The order below is varied so that the co-respondent shall pay the husband $3,890 to account of the investigation costs." (at [23])
Regarding the costs of the divorce proceedings themselves, the District Judge’s order that the co-respondent pay 50% of the costs (fixed at $1,500) and $400 for the costs of the hearing on the co-respondent's liability remained undisturbed as they were not the primary focus of the appeal's variation. However, the High Court had to address the costs of the appeal itself. Justice Prakash noted that while the husband did not succeed in recovering the full $8,780, he was successful in significantly increasing the award. Therefore, the husband was entitled to costs for the appeal. The court directed that if the parties could not agree on the amount, they should return to her for a determination.
The final financial disposition was as follows:
- Investigation Costs: Co-respondent to pay $3,890 to the husband.
- Divorce Proceeding Costs: Co-respondent to pay $750 (50% of $1,500) as per the lower court's undisturbed ratio.
- Ancillary Hearing Costs: Co-respondent to pay $400.
- Appeal Costs: To be paid by the co-respondent to the husband, to be taxed if not agreed.
Why Does This Case Matter?
The significance of Goh Yong Hng v Cheong Yen Teng lies in its pragmatic calibration of the financial consequences of adultery in Singapore's legal landscape. It provides a clear framework for how the "reasonableness" of private investigation fees should be assessed, moving away from a "bare minimum" approach to one that recognizes the practicalities of litigation preparation.
First, the case establishes that "reasonableness" in surveillance is not limited to the moment the first piece of evidence is obtained. By allowing the costs for three days of surveillance even after the first day yielded results, Justice Prakash acknowledged the forensic necessity of establishing a pattern of behavior or ensuring corroboration. This is a vital protection for petitioners who might otherwise fear that thoroughness in evidence-gathering would be penalized during the taxation of costs. It confirms that the court will support a petitioner's right to build a "watertight" case.
Second, the judgment clarifies the limits of what a co-respondent can be forced to subsidize. By excluding the costs of the investigator's attendance at the 15 May meeting, the court drew a sharp line between "litigation costs" and "personal costs." This prevents the costs indemnity rule from being used to fund personal confrontations or emotional closure, ensuring that the co-respondent is only liable for expenses strictly necessary for the legal process.
Third, the case reinforces the 50% apportionment rule in cases of adultery. It acknowledges the "it takes two to tango" reality of infidelity. Even if a co-respondent is the catalyst for the litigation, the wife’s voluntary participation means the co-respondent should not typically bear 100% of the investigative burden. This provides a predictable baseline for practitioners when advising clients on potential cost recovery.
Finally, the decision distinguishes the "dead marriage" exception found in Tan Kay Poh v Tan Surida. It clarifies that as long as the marriage has not completely and irrevocably broken down prior to the adultery, the co-respondent remains liable for the costs of the litigation that the adultery triggered. This protects the sanctity of the marriage up until the point of legal or actual dissolution, ensuring that third-party interlopers cannot easily escape cost liability by claiming the marriage was already "shaky."
Practice Pointers
- Advise on the "Watertight" Standard: Practitioners should inform clients that while the court allows for multiple days of surveillance to ensure a robust case, there is a limit. Surveillance extending significantly beyond what is needed to prove the "fact" of adultery may still be deemed unreasonable.
- Separate Legal and Personal Meetings: Costs for private investigators to attend "confrontation" meetings or mediation-style encounters between the parties are unlikely to be recoverable. Clients should be warned that such expenses will likely be borne personally.
- Manage Expectations on Apportionment: Even if a co-respondent is clearly at fault, the "default" recovery for investigation costs is often 50%, reflecting the shared responsibility of the adulterous spouse. Practitioners should not promise 100% recovery of PI fees.
- Scrutinize PI Invoices: Before seeking reimbursement, lawyers should review PI bills for "padding." Items like excessive report-writing fees (as seen in the reduction from $1,010 to $610 in this case) are frequent targets for judicial reduction.
- Document the State of the Marriage: Since the co-respondent may rely on Tan Kay Poh to avoid costs, it is crucial for the petitioner to gather evidence showing the marriage was still viable (even if troubled) prior to the co-respondent's involvement.
- Implied Admissions: An offer by a co-respondent to pay PI fees can be pleaded as an implied admission of adultery, as was successfully done in this case.
Subsequent Treatment
This case is frequently cited in the Family Justice Courts of Singapore as the leading authority on the quantification of private investigator fees. It is the standard reference for the proposition that a petitioner is entitled to conduct sufficient surveillance to ensure a "watertight" case, and for the application of the 50% apportionment rule between a co-respondent and the respondent spouse. It has effectively settled the debate on whether "but-for" causation is sufficient for cost recovery, tempering it with the "reasonableness" requirement of the Rules of Court.
